Characteristics Of Life Quiz

The chemical equation for cellular respiration is C6H12O6 + 6 O2 --> 6 CO2 + 6 H2O + ATP. This equation represents the process in which glucose (C6H12O6) and oxygen (O2) are converted into carbon dioxide (CO2), water (H2O), and ATP (adenosine triphosphate), which is the energy currency of cells. This equation accurately represents the reactants and products involved in cellular respiration.

This scenario demonstrates the COL of "Respond to Stimuli" because the loud noise of the car backfiring acts as a stimulus that triggers a response in the form of screaming and running away. The individual's reaction is instinctive and automatic, showing their ability to respond to external stimuli in their environment.

Cells are the smallest structural unit of life that maintains all the properties of life. They are the basic building blocks of all living organisms and are responsible for carrying out essential functions such as metabolism, growth, and reproduction. Cells are composed of various molecules and organelles, which work together to ensure the survival and functioning of the organism.

The correct answer is Stone: Never Alive; Frozen Fish: Once Living; Grass: Alive. This answer correctly categorizes the objects based on their characteristics. It states that stone is never alive, which is true as stones do not possess life. It states that frozen fish is once living, which is true as fish were once alive before being frozen. It states that grass is alive, which is also true as grass is a living plant.

Adaptation is important for a species because it allows them to adapt to changing environments, ensuring their survival. This means that they can adjust to new conditions and continue to thrive. On the other hand, reproduction is crucial to prevent the species' numbers from getting too low, which could lead to extinction. By reproducing, individuals pass on their genetics to future generations, maintaining a healthy population size and genetic diversity. Together, adaptation and reproduction work hand in hand to ensure the species' survival and long-term success.

Living organisms require a fuel source that can be converted into ATP energy, and glucose is the primary fuel source for most organisms. Glucose is a type of sugar that is broken down through a process called cellular respiration to produce ATP, which is the energy currency of cells. This process occurs in the mitochondria of cells and is essential for maintaining the energy needs of living organisms.

Plants need to undergo photosynthesis to create glucose. Glucose is a type of sugar that serves as a source of energy for plants. Through photosynthesis, plants convert sunlight, water, and carbon dioxide into glucose and oxygen. Glucose is then used by plants for various metabolic processes, including growth, reproduction, and cellular respiration. Additionally, plants store excess glucose as starch, which can be used as a long-term energy reserve. Therefore, photosynthesis is crucial for plants to produce the necessary energy and nutrients needed for their survival and growth.

Plants use both cellular respiration and photosynthesis to obtain energy. Photosynthesis allows plants to convert sunlight, water, and carbon dioxide into glucose and oxygen. This process occurs in the chloroplasts of plant cells. However, plants also require energy for various metabolic processes, growth, and reproduction. This energy is obtained through cellular respiration, which takes place in the mitochondria of plant cells. Animals, on the other hand, rely solely on cellular respiration to obtain energy from the food they consume. Therefore, the correct answers are that plants use both cellular respiration and photosynthesis, while animals use cellular respiration only.

Cells are considered the smallest structural unit of life because they are capable of carrying out all the essential functions of life. They are the building blocks of all living organisms and are responsible for maintaining life-sustaining processes such as metabolism, growth, reproduction, and response to stimuli. Cells can exist as single-celled organisms or as part of a multicellular organism, where they work together to form tissues, organs, and ultimately, an entire organism.

The correct answer is Dried Flowers: Once Alive, Algae: Living, Bacteria: Alive. This is because dried flowers were once alive but are now dead, algae is a type of plant that is living, and bacteria are living microorganisms.

The presence of two bacteria cells in the petri dish after half an hour indicates growth and reproduction. Growth refers to an increase in size or number, which is evident from the larger size of the bacteria cells. Reproduction involves the production of offspring, which is evident from the presence of two bacteria cells instead of just one. Therefore, the example provided demonstrates both growth and reproduction, which are characteristics of life.

The scientist's examination of the elephant and mouse reveals that both organisms have a similar digestive system, with an esophagus that leads to the stomach and then to the intestines. This observation demonstrates the characteristic of Biological Organization, as it shows that both organisms have a similar organization of their internal structures and systems.

Over many generations, adaptation leads to the selection of the individuals within that species who are best able to respond to specific stimuli within their environment. This means that as a species adapts to its environment, individuals who are better equipped to respond to stimuli in that environment have a higher chance of survival and reproduction. Over time, this leads to the selection and proliferation of individuals with traits that enable them to respond effectively to the stimuli present in their environment.

All of the given options are examples of development. The formation of arms on the tadpole, the change in the tadpole's heart chambers, and the disappearance of the tadpole's tail are all specific examples of development in the process of a tadpole transforming into a frog.

Reproduction ensures that the species is genetically able to cope with changing environments. This is because through reproduction, individuals with advantageous genetic traits are able to pass on those traits to their offspring, increasing the overall fitness of the species and enabling them to adapt to their environment. Adaptation, on the other hand, refers to the process by which populations evolve over time in response to environmental changes. It does not directly ensure that only the best genetics are passed along to future generations, as adaptation can occur through various mechanisms such as natural selection, genetic drift, and gene flow.

On a hot day, a dog can respond to stimuli by lowering its body temperature through panting, which is similar to sweating in humans. Additionally, finding and laying down in a shade can help the dog cool down. Lastly, locating and drinking water is also an appropriate response as it helps to hydrate the dog and regulate its body temperature. However, altering its DNA to have less fur is not a response to stimuli but rather a long-term genetic adaptation.

The increase in the number of unicellular bacteria cells in the petri dish from 2 to 14 in a half hour demonstrates the characteristic of growth. Growth refers to an increase in size, number, or complexity. In this case, the number of cells has increased, indicating growth in the bacterial population.

An object that was once living refers to something that was once alive but no longer possesses the characteristics of life. This could be a plant that has died or an animal that has decomposed. Once living objects were once capable of growth, reproduction, response to stimuli, metabolism, and organization, but they have lost these abilities over time.

The truck is never living because it is an inanimate object and does not possess life. The squirrel is living before crossing the road because it is described as running. The driver is living because they pull over to check on the squirrel. The squirrel is once living after crossing the road because it is hit by the truck and killed.

When the light is turned on in a dark room, the cockroaches scurrying underneath a cabinet is an example of the characteristic of life known as "Respond to Stimuli". The cockroaches are reacting to the sudden change in their environment caused by the introduction of light, and they are exhibiting a response by moving quickly to find shelter. This ability to detect and respond to external stimuli is a fundamental aspect of living organisms.

The given question asks for the best description of a single cell increasing in size and mass over time. The process described here is commonly known as growth. Growth refers to an increase in size, mass, or complexity of an organism or its parts over time. This answer aligns with the provided information and accurately describes the given scenario.

The image of tadpoles forming new structures such as legs demonstrates the COL of Development because it shows the process of growth and differentiation. Development involves the formation of new structures and organs as an organism matures. In this case, the tadpoles are undergoing metamorphosis, transitioning from their larval stage to their adult stage. The formation of legs is a clear indication of developmental changes occurring in the tadpoles.

The correct answer is 6 CO2 + 6 H2O --> C6H12O6 + 6 O2. This equation represents the process of photosynthesis, where carbon dioxide (CO2) and water (H2O) are converted into glucose (C6H12O6) and oxygen (O2) using light energy. This equation is balanced, with 6 molecules of CO2 and 6 molecules of H2O on the reactant side, and 1 molecule of C6H12O6 and 6 molecules of O2 on the product side.

Plants use both photosynthesis and cellular respiration to obtain energy. Photosynthesis is the process by which plants convert sunlight, carbon dioxide, and water into glucose and oxygen. Cellular respiration, on the other hand, is the process by which plants break down glucose and release energy. Animals, on the other hand, rely solely on cellular respiration to obtain energy from the food they consume. Therefore, the correct answer is that plants use both photosynthesis and cellular respiration, while animals use cellular respiration only.

The observations mentioned in the question indicate that the creature is constantly changing position, releasing bubbles, and responding to changes in temperature. Additionally, the fact that two smaller creatures appear from the original after 2 days suggests reproduction. These observations suggest that the creature is using energy to move, responding to stimuli such as changes in temperature, and reproducing. Therefore, the best C.O.L. that these observations can apply to is "Using Energy, Reproduction, Respond to Stimuli."

The statement that is false regarding the difference between Adaptation and Response to a Stimuli is "Adaptation: occurs when someone acclimates (gets used to) the weather; Response to a Stimulus: occurs only when internal body conditions are changing." This is incorrect because adaptation is not specific to acclimating to weather, but rather refers to changes that occur in an entire species over many generations. Response to a stimulus, on the other hand, can occur in single individuals and can happen instantaneously without genetic changes.

During photosynthesis, plants take in carbon dioxide (CO2) from the atmosphere and water (H2O) from the soil. Using sunlight as an energy source, they convert CO2 and H2O into glucose and release oxygen (O2) as a byproduct. This process is represented by the equation: 6CO2 + 6H2O → C6H12O6 + 6O2. During cellular respiration, organisms break down glucose to release energy. In this process, they take in oxygen (O2) and release carbon dioxide (CO2) as a waste product. The overall flow of materials is therefore CO2 being taken in during photosynthesis, O2 being released, and CO2 being released during cellular respiration.

All living organisms undergo cellular respiration, which is the process of converting nutrients into energy. Cats, fish, eagles, and roses are all living organisms, therefore they all undergo cellular respiration.

The presence of grouped cells that form tissues and a four chambered heart in all three organisms indicates a high level of organization. This suggests that the organisms have specialized structures and systems that work together to perform specific functions. The concept of organization best explains this observation.

During the drought, the birds with bigger beaks have an advantage in obtaining food from tough shells. However, the statement that none of the individual birds will be able to adapt because they are born with their genetics and cannot alter it is true. Adaptation occurs over generations through natural selection, where individuals with advantageous traits are more likely to survive and reproduce. In this scenario, the birds with smaller beaks may struggle to find enough food, but they will not be able to adapt by growing larger and stronger beaks within their lifetime.

The correct answer is that Statement 1 is an adaptation and Statement 2 is a response to a stimulus.

Statement 1 describes how an elephant's large ears with many tiny blood vessels are an adaptation that allows them to effectively cool their internal body temperature by waving their ears in the air during hot days. This adaptation helps elephants regulate their body temperature and survive in hot environments.

Statement 2 describes how a young girl sitting in the hot sun responds to the stimulus of the heat by folding a piece of paper into the shape of a fan and waving it back and forth to create a cool breeze. This is a response to the stimulus of the hot sun and is a way for the girl to try to cool down her internal body temperature.

Offspring often resemble parent organisms that are best suited to their environment because these organisms have traits that enable them to survive and reproduce successfully. Through the process of natural selection, individuals with advantageous traits are more likely to survive and pass on their genes to the next generation. Over time, these traits become more common in the population, leading to offspring that are well adapted to their environment. This ensures the continuation of favorable traits and increases the overall fitness of the species.

The given scenario describes the sunflower's ability to bend and twist in order to face the sun as it moves across the sky. This behavior of the sunflower is a response to the stimulus of sunlight. Therefore, the best way to describe this behavior is "Responding to Stimuli".

Movement and acclimation are not characteristics of life. Movement refers to the ability of an organism to change its position or location, which is not a defining characteristic of life as there are many non-living things that can also move. Acclimation refers to the ability of an organism to adjust to changes in its environment, which is also not a defining characteristic of life as there are non-living systems that can also acclimate. Development, biological organization, and reproduction are all characteristics of life as they are essential processes for living organisms.

Photosynthesis is the correct answer because it is the process by which plants, algae, and some bacteria convert sunlight, carbon dioxide, and water into glucose and oxygen. This glucose is then used as the primary source of energy for almost all living organisms through cellular respiration. Combustion is a chemical process that produces energy, but it is not the main process that sustains living organisms. Consuming plants and digestion are part of the process of obtaining energy from food, but they are not the chemical processes that produce the energy needed for living things.

Adaptation is a characteristic of life that is required for the survival of a species as a whole, but it is not necessary for an individual organism. Adaptation refers to the ability of a species to change and adjust to its environment over time, allowing it to better survive and reproduce. While individuals within a species may exhibit certain adaptations, it is not a requirement for their survival. Similarly, reproduction is essential for the continuation of a species, but it is not necessary for an individual organism to reproduce in order to survive.

All of the organisms listed undergo cellular respiration. Cellular respiration is the process by which cells break down glucose and other organic molecules to produce energy in the form of ATP. This process occurs in all living organisms, including animals like sharks, zebras, and worms, as well as plants like daisies. Therefore, cellular respiration is a fundamental metabolic process that is essential for the survival and functioning of all organisms.

The given answer, "Growth," is correct because it accurately describes the process of an organism increasing in size, mass, and number of cells. Growth is a fundamental characteristic of life, as living organisms have the ability to grow and develop over time.

The correct answer is "...it can (a) obtain, (b) covert, & (c) use biological energy". This statement incorrectly applies the characteristics of life to the camera. Cameras do not have the ability to obtain, convert, or use biological energy as living organisms do. Cameras rely on external power sources such as batteries or electricity to function, rather than biological energy.

The given answer is correct because the mass and number of cells increasing in a caterpillar as it eats leaves is an example of growth, not development. Development refers to the process of maturation and differentiation of cells, tissues, and organs to form a complete organism or to acquire specific functions. In this case, the caterpillar changing into a butterfly, the formation of the baby's heart chambers, and the disappearance of a tadpole's tail are all examples of development.

The given answer suggests that the number of white species will decrease significantly after a few days, while the number of brown species will only decrease slightly. This implies that there may be some factors or conditions that are causing a decline in the white species population, while the brown species population is relatively stable or experiencing a minor decrease.

As an adult, the brown bear that was transported from a forest to the arctic as a cub will seek out caves and shelter to avoid cold winters. This behavior is a survival adaptation to the harsh arctic environment, where the bear needs protection from extreme cold temperatures. On the other hand, there is no mention of the bear's fur changing color in the question, so it cannot be concluded that the bear will grow lighter and lighter fur to match the "snow" environment. Therefore, only statement a is true.

The sequence of events in the image can be best described as Development. Development refers to the process of growth and change over time, which includes responding to stimuli, reproduction, growth, and adaptation. Homeostasis, on the other hand, refers to the ability to maintain a stable internal environment, which may not be applicable in this context. Therefore, Development is the most suitable COL to describe the sequence of events in the image.

Movement and Photosynthesis are not characteristics of life. Movement is a characteristic of living organisms, as they are capable of changing their position or location. Photosynthesis, on the other hand, is a process that occurs in plants and some bacteria to convert sunlight into energy, which is essential for their survival. Adaptation and Development, however, are characteristics of life. Adaptation refers to the ability of organisms to adjust to their environment over time, while development refers to the process of growth and maturation of an organism from birth to adulthood.

The characteristics of life that are required for an individual within a species are to develop and grow, respond to stimuli, and obtain, convert, and use energy. Developing and growing is essential for an individual to mature and reach their full potential. Responding to stimuli allows an organism to interact with its environment and adapt to changes. Obtaining, converting, and using energy is necessary for an individual to carry out essential life processes and maintain homeostasis.

Photosynthesis is the process by which plants convert sunlight, water, and carbon dioxide into glucose and oxygen. Oxygen is produced as a byproduct of photosynthesis, while water and sunlight are essential reactants for the process. Carbon dioxide is also required for photosynthesis, but it is not listed as a reactant in the given options. Glucose and ATP are products of photosynthesis and not reactants.

The given balanced chemical equation represents cellular respiration, which is the process by which cells convert glucose (C6H12O6) and oxygen (O2) into carbon dioxide (CO2), water (H2O), and ATP (adenosine triphosphate). ATP is the energy currency of cells. This equation shows that for every molecule of glucose and oxygen, six molecules of carbon dioxide, six molecules of water, and ATP are produced.

The statement incorrectly applies the characteristics of life to the photocopier because having moving parts does not necessarily mean that an object is alive. Many non-living objects, such as machines and vehicles, have moving parts for their functionality.

During photosynthesis, organisms take in carbon dioxide (CO2) and water (H2O) and convert them into oxygen (O2) and glucose (C6H12O6). This process occurs in the presence of sunlight and is carried out by chlorophyll in the chloroplasts of plant cells. The oxygen produced during photosynthesis is released into the atmosphere.

During cellular respiration, organisms take in oxygen (O2) and glucose (C6H12O6) and convert them into carbon dioxide (CO2), water (H2O), and energy. This process occurs in the mitochondria of cells and is used to produce ATP, the energy currency of cells. The carbon dioxide produced during cellular respiration is released into the atmosphere.

Therefore, the correct answer is a= O2; b= C6H12O6; c= CO2; d= H2O; e=O2.
