This scenario demonstrates the concept of responding to stimuli. The car backfiring is the stimulus that triggers a response in the form of screaming and running away. This response is a direct reaction to the unexpected and loud noise, which is a natural instinct for many people to protect themselves from potential danger. Therefore, the correct answer is "Respond to Stimuli."

The given correct answer for this question is "Growth". Growth refers to the increase in size and mass of a single cell over time. This process involves the synthesis of new molecules and the accumulation of additional cellular material, resulting in an overall increase in cell size. Development, movement, responding to stimuli, adaptation, and reproduction are not the most accurate descriptions for the given scenario.

The fact that humans have hearts, stomachs, and bones indicates that our bodies are highly organized biologically. These organs and structures work together in a coordinated manner to perform essential functions like pumping blood, digesting food, and providing structure and support. This level of organization is a characteristic of complex living organisms and demonstrates the intricate design and functionality of the human body.

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

Offspring often resemble parent organisms that are best suited to their environment because these organisms have inherited traits that are advantageous for survival and reproduction. Through natural selection, organisms with these beneficial traits are more likely to survive and pass on their genes to the next generation. Over time, this leads to a population of organisms that are well adapted to their environment, as they have inherited the traits that allowed their parents to thrive.

An object that was once living refers to something that was once alive but no longer possesses the characteristics of life. This could include things like a dead plant or animal, which were once living organisms but have now lost the ability to grow, reproduce, respond to stimuli, and carry out other life functions.

Movement is not a characteristic of life because not all living organisms are capable of moving. Some organisms, such as plants, are rooted in one place and cannot move. However, they are still considered living because they exhibit other characteristics of life such as being made of cells, responding to stimuli, and reproducing. Movement is a characteristic that is specific to certain organisms, but it is not a universal characteristic of all living things.

The characteristic of life that doesn't apply to an individual but only to our species is "Reproduce". While individuals may reproduce to create offspring, it is not a characteristic that applies to every individual. Some individuals may be unable or choose not to reproduce, but the species as a whole must reproduce in order to continue its existence.

Plants obtain the energy needed for cellular functions through photosynthesis. During photosynthesis, plants use sunlight, water, and carbon dioxide to produce glucose and oxygen. The glucose is then used as a source of energy for various cellular processes, such as growth, reproduction, and metabolism. This process is essential for plants to survive and thrive, as it allows them to convert sunlight into usable energy. Cellular respiration is another important process, but it is not how plants obtain energy initially. Adaptation and reproduction are unrelated to the energy acquisition of plants.

The given statement describes an organism increasing in size, mass, and number of cells, which is a clear indication of growth. Growth is a characteristic of life that involves an increase in size or number of cells in an organism over time. It is a fundamental process that allows organisms to develop and mature.

The correct answer categorizes the objects based on their state of being alive or dead. Dried flowers are classified as "once alive" because they were living organisms at some point but have since died and dried out. Algae is categorized as "living" because it is currently alive. Bacteria is also classified as "alive" because it is currently living.

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 universal characteristic of all living organisms. Acclimation, on the other hand, refers to the ability of an organism to adjust to changes in its environment, which is more of a physiological response rather than a characteristic of life itself. Development, biological organization, and reproduction are all characteristics of life as they involve growth, organization of cells or tissues, and the ability to produce offspring, respectively.

Plants use both photosynthesis and cellular respiration 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. Cellular respiration, on the other hand, takes place in the mitochondria of plant cells and involves breaking down glucose to release energy in the form of ATP. Animals, on the other hand, only use cellular respiration to obtain energy. They do not have the ability to perform photosynthesis.

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, reproducing, and growing. This sequence suggests that the organism in the image is undergoing various stages of development, such as maturing, reproducing, and adapting to its environment. Homeostasis and adaptation are also important processes in an organism's development, but they are not specifically mentioned in the given sequence.

Cells are the smallest structural unit of life that maintains all the properties of life. Cells are the basic building blocks of all living organisms and are capable of carrying out essential life processes such as metabolism, growth, reproduction, and response to stimuli. Atoms and molecules are smaller components that make up cells, but they do not possess all the properties of life on their own. Tissues, organs, and organisms are composed of multiple cells working together, but they are not the smallest unit that maintains all the properties of life.

Plants need to undergo photosynthesis in order to create glucose. Glucose is a type of sugar that serves as the main source of energy for plants. Through photosynthesis, plants use sunlight, water, and carbon dioxide to produce glucose and oxygen. Glucose is then used by plants for various metabolic processes, such as growth, reproduction, and storing energy. Additionally, plants can convert excess glucose into other carbohydrates, such as starch, for long-term storage. Overall, photosynthesis is essential for plants to produce glucose and sustain their growth and survival.

Plants use both cellular respiration and photosynthesis because they need energy for their metabolic processes. Photosynthesis allows plants to convert sunlight into energy in the form of glucose, while cellular respiration breaks down glucose to release energy. Animals, on the other hand, only use cellular respiration to obtain energy from the food they consume. They do not have the ability to perform photosynthesis.

The sunflower's ability to bend and twist to face the sun is an example of responding to stimuli. The stimuli in this case is the movement of the sun across the sky. The sunflower is able to detect this stimulus and respond by adjusting its position to maximize exposure to sunlight. This behavior allows the sunflower to optimize its photosynthesis process and ensure its survival.

The image of tadpoles forming new structures such as legs demonstrates the COL of Development because it shows the process of growth and differentiation. During development, tadpoles undergo metamorphosis where they transform from aquatic larvae to terrestrial adults. The formation of new structures, such as legs, is a clear indication of the developmental changes that occur in tadpoles as they transition into adulthood.

Living organisms require a fuel source that can be converted into ATP energy. Glucose is the fuel source that can be converted into ATP through a process called cellular respiration. Glucose is broken down in the presence of oxygen to produce ATP, which is the primary source of energy for cellular activities. Oxygen is necessary for the complete breakdown of glucose, but glucose itself is the fuel that is converted into ATP. Sunlight is used by plants in photosynthesis to produce glucose, but it is not directly used as a fuel source by organisms. Carbon dioxide and water are byproducts of cellular respiration, not the fuel source itself.

The given balanced chemical equation represents cellular respiration, where glucose (C6H12O6) and oxygen (O2) react to produce carbon dioxide (CO2), water (H2O), and ATP (adenosine triphosphate). This equation follows the stoichiometry of the reactants and products, balancing the number of atoms on both sides of the equation.

ANIMALS and PLANTS convert glucose to ATP energy needed for cellular functions through Cellular Respiration. This process occurs in the mitochondria of cells and involves the breakdown of glucose molecules to produce ATP, which is the main energy currency of cells. Cellular Respiration consists of three main stages: glycolysis, the Krebs cycle, and oxidative phosphorylation. During these stages, glucose is gradually broken down, releasing energy that is used to produce ATP. This process is essential for the survival and functioning of both animals and plants.

Movement and Photosynthesis are not characteristics of life. Movement refers to the ability of an organism to change its position or location, which is not a universal characteristic of all living things. Photosynthesis, on the other hand, is a process that occurs in plants and some bacteria, where they convert light energy into chemical energy. While photosynthesis is essential for the survival of certain organisms, it is not a characteristic shared by all forms of life.

All of the organisms listed undergo cellular respiration. Cellular respiration is the process by which cells convert glucose and oxygen into carbon dioxide, water, and energy in the form of ATP. This process occurs in all living organisms, including sharks, daisies, zebras, and worms.

On a hot day, dogs respond to stimuli by lowering their body temperature through panting, which is their way of sweating. They also find and lay down in a shade to avoid direct sunlight and further heat exposure. Additionally, they locate and drink water to stay hydrated and cool down. Altering DNA to have less fur is not a suitable response to stimuli for a dog on a hot day.

The correct answer is 6 CO2 + 6 H2O --> C6H12O6 + 6 O2. This chemical equation represents the process of photosynthesis, where carbon dioxide and water are converted into glucose (C6H12O6) and oxygen (O2) in the presence of sunlight. This equation accurately represents the balanced chemical reaction that occurs during photosynthesis.

Green plants are the primary producers in the food chain and are capable of photosynthesis, which converts sunlight into chemical energy. This energy is then passed on to other organisms through the consumption of plants or plant-eating animals. Therefore, all of the energy obtained through the food we eat ultimately comes from green plants.

Adaptation is a characteristic of life that is required for the survival of a species as a whole, but it is not necessary for each individual within the species. Adaptation refers to the ability of a species to adjust to its environment over time in order to enhance its chances of survival and reproduction. While individuals within a species may exhibit certain adaptations, it is not a necessary requirement for their survival. Reproduction, on the other hand, is essential for the continuation of a species, as it ensures the production of new individuals that can carry on the genetic information and traits of the species.

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 a source of energy for almost all living organisms through cellular respiration. Combustion is a chemical process that produces energy through the burning of fuel, but it is not the primary source of energy for living things. Consuming plants and digestion are part of the process by which organisms obtain energy, but they are not the chemical processes that produce the energy itself.

All living organisms undergo cellular respiration, which is the process of converting glucose and oxygen into carbon dioxide, water, and energy in the form of ATP. This process occurs in the cells of animals, plants, and even some bacteria. Therefore, cats, roses, fish, and eagles all undergo cellular respiration to produce energy for their survival and growth.

An individual within a species must develop and grow in order to reach maturity and fulfill its potential. They must also be able to respond to stimuli in their environment in order to survive and adapt. Lastly, they must obtain, convert, and use energy to carry out life processes such as metabolism and growth.

Living things share several common characteristics. Development refers to the process of growth and maturation that all living organisms go through. Biological organization refers to the hierarchical structure of living things, from cells to tissues, organs, and organ systems. Reproduction is the ability to produce offspring, ensuring the continuation of the species. Cells are the basic unit of life, present in all living organisms. Adaptation allows living things to adjust to their environment and survive. Lastly, the ability to respond to stimuli is crucial for living organisms to interact with their surroundings and maintain homeostasis.

Photosynthesis is the process by which plants convert sunlight, water, and carbon dioxide into glucose and oxygen. Water is one of the reactants needed for photosynthesis as it provides the hydrogen atoms necessary for the formation of glucose. Sunlight is also required as it provides the energy needed to drive the chemical reactions of photosynthesis. Carbon dioxide is another reactant as it provides the carbon atoms necessary for the formation of glucose. Therefore, the correct answer is water, sunlight, and carbon dioxide.

Cellular respiration is the process by which cells convert glucose and oxygen into carbon dioxide, water, and ATP (adenosine triphosphate). Glucose is the main source of energy for cellular respiration, while oxygen acts as the final electron acceptor in the electron transport chain, allowing for the production of ATP. Therefore, both oxygen and glucose are required as reactants for cellular respiration to occur. The other options listed, such as water, sunlight, and ATP, are not reactants but rather byproducts or products of cellular respiration.
