    A change in a organism's surroundings that causes it to react is called a

    Correct Answer
    stimulus
    Explanation
    A stimulus is a change in an organism's surroundings that triggers a reaction. It can be anything from a change in temperature, light, sound, or touch that causes an organism to respond in some way. The reaction can be a physical movement, a change in behavior, or even a physiological response. Stimuli are essential for organisms to adapt and survive in their environment, as they allow them to detect and respond to changes in their surroundings.

    Rate this question:

  • 5. 

    An organism reacts to a stimulus with a

    Correct Answer
    response
    Explanation
    An organism reacts to a stimulus with a response. This means that when an organism is exposed to a stimulus, such as a change in temperature or the presence of food, it will exhibit a reaction or response. This response can be a physical action, such as moving away from a harmful stimulus, or a physiological change, such as an increase in heart rate. The ability to respond to stimuli is a fundamental characteristic of living organisms and is essential for their survival and adaptation to their environment.

    The mistaken idea that living things can arise from nonliving things

    Correct Answer
    spontaneous generation
    Explanation
    Spontaneous generation refers to the incorrect belief that living organisms can arise from non-living matter without the need for pre-existing life. This theory was widely accepted in the past, with people believing that things like maggots spontaneously appeared from decaying meat or that mice could be generated from dirty rags. However, through scientific experiments and observations, it was eventually proven that life only arises from pre-existing life, leading to the rejection of the concept of spontaneous generation.

    Rate this question:

  • 7. 

    What is an experiment called that carries out two test that are identical in every respect except one factor

    Correct Answer
    controlled experiment
    Explanation
    A controlled experiment is a type of experiment where two tests are conducted, and they are identical in every aspect except for one factor. This allows researchers to isolate and study the effects of that specific factor on the outcome of the experiment. By controlling all other variables, the researchers can determine whether the observed differences in the outcomes are solely due to the manipulated factor. This type of experiment helps establish cause-and-effect relationships and is commonly used in scientific research to investigate the impact of various factors on a particular phenomenon.

    What was the name of the French chemist that helped to disprove spontaneous generation in the 1800's

    Correct Answer
    Louis Pasteur
    Explanation
    Louis Pasteur was a French chemist who played a crucial role in disproving the theory of spontaneous generation in the 1800s. Through his experiments, Pasteur demonstrated that microorganisms do not arise spontaneously but instead come from pre-existing microorganisms. His famous experiments with swan-necked flasks showed that if the neck of the flask was broken, allowing air to come into contact with the broth, microorganisms would appear. This proved that the air carried microorganisms, rather than them spontaneously generating. Pasteur's work laid the foundation for the field of microbiology and revolutionized our understanding of the origin of life.

    All living things must satisfy their basic needs for  what four things

    Correct Answer
    food,water,living space and stable internal conditions
    Explanation
    Living things need four things to satisfy their basic needs: food, water, living space, and stable internal conditions. Food provides the necessary nutrients for growth and energy, while water is essential for various bodily functions. Living space refers to the environment where organisms can find shelter, reproduce, and carry out their activities. Lastly, stable internal conditions, also known as homeostasis, ensure that the body's internal environment remains stable and balanced, allowing for proper functioning of cells and organs.

  • 10. 

    Organisms that make their own food are called

    Correct Answer
    autotrophs
    Explanation
    Autotrophs are organisms that have the ability to produce their own food using energy from the sun or other inorganic substances. They are able to convert sunlight into energy through the process of photosynthesis or obtain energy from inorganic compounds through chemosynthesis. Autotrophs play a crucial role in the food chain as they are the primary producers, providing energy and nutrients for other organisms. Examples of autotrophs include plants, algae, and some bacteria.

    Rate this question:

  • 11. 

    Organisms that can not make their own food are called

    Correct Answer
    heterotrophs
    Explanation
    Heterotrophs are organisms that cannot produce their own food and rely on consuming other organisms or organic matter for their energy and nutrients. They obtain their energy by consuming autotrophs or other heterotrophs. This is in contrast to autotrophs, which can produce their own food through processes like photosynthesis. Heterotrophs include animals, fungi, and many types of bacteria. They play a crucial role in ecosystems by decomposing dead organisms and recycling nutrients back into the environment.

    What is homeostasis

    Correct Answer
    Explanation
    Homeostasis is the body's ability to maintain a stable internal environment despite external changes. It involves a series of physiological processes that regulate temperature, blood pressure, pH levels, and other vital functions within a narrow range. These processes are controlled by feedback mechanisms, such as negative feedback loops, that detect and counteract any deviations from the body's set point. Homeostasis is crucial for the overall well-being and proper functioning of the body, ensuring that cells and organs receive the necessary conditions to carry out their functions effectively.

    What is the process called that groups things together by similarities

    Correct Answer
    classification
    Explanation
    Classification is the process of grouping things together based on their similarities. It involves categorizing or organizing objects, ideas, or data into specific groups or classes based on shared characteristics or attributes. This process helps in organizing and understanding complex information by identifying patterns and relationships among different elements. Classification is commonly used in various fields such as science, biology, psychology, and data analysis to make sense of large amounts of data and to simplify complex systems.

    The scientific study of how living things are classfied is called

    Correct Answer
    taxonomy
    Explanation
    Taxonomy is the branch of science that focuses on classifying and categorizing living organisms based on their characteristics and evolutionary relationships. It involves the identification, naming, and classification of organisms into different hierarchical levels such as kingdom, phylum, class, order, family, genus, and species. By studying taxonomy, scientists can better understand the diversity of life on Earth and how different species are related to each other. This helps in organizing and organizing information about living organisms, making it easier to study and communicate about them.

    The naming system that Linnaeus used is called

    Correct Answer
    binomial nomenclature
    Explanation
    Linnaeus used the naming system called binomial nomenclature. This system involves giving each species a two-part scientific name consisting of the genus and species. The genus is a broader category that groups similar species together, while the species name specifies the particular organism within that genus. This system allows for clear and standardized identification of species, as each name is unique and universally recognized. It also provides a hierarchical structure for classifying and organizing organisms based on their evolutionary relationships. Binomial nomenclature is still widely used in modern taxonomy.

  • 16. 

    The first word in a organism's scientific name is its

    Correct Answer
    genus
    Explanation
    The first word in an organism's scientific name is its genus. In taxonomy, organisms are classified into different categories based on their characteristics. The genus is a higher-level classification that groups together species that share similar traits. It is the first part of the binomial nomenclature system, which is used to give each species a unique scientific name. The genus name is always capitalized and italicized, and it is followed by the species name, which together form the complete scientific name of the organism.

    The process by which species gradually change over time is called

    Correct Answer
    evolution
    Explanation
    Evolution refers to the gradual change in species over time. It is a process that occurs through the accumulation of small genetic variations over generations, leading to the development of new traits and species. This process is driven by natural selection, where individuals with advantageous traits are more likely to survive and reproduce, passing on their genes to the next generation. Over millions of years, these small changes can result in significant differences between species, allowing them to adapt and thrive in their respective environments.

    • A.

      It showed that bacteria do not arise spontaneously

    • B.

      The neck of both flasks were curved

    • C.

      Boiling or not boiling was the only variable

    • D.

      The broth in both flask remained clear

    Correct Answer
    C. Boiling or not boiling was the only variable
    Explanation
    The experiment conducted by Pasteur, where he boiled broth in some flasks but not in others, was a controlled experiment because boiling or not boiling was the only variable. This means that all other factors were kept constant and only the presence or absence of boiling was changed. By comparing the results of the boiled and unboiled flasks, Pasteur was able to conclude that bacteria do not arise spontaneously, as the broth in the unboiled flasks remained clear. The curved necks of the flasks are not relevant to the controlled nature of the experiment.

    What is the major difference between fungi and plants?

    Correct Answer
    Fungi are heterotrophs;plants are autotrophs
    Explanation
    Fungi and plants differ in their mode of obtaining nutrients. Fungi are heterotrophs, meaning they obtain their nutrients by consuming organic matter from their environment. They do not have the ability to produce their own food through photosynthesis. On the other hand, plants are autotrophs, which means they can produce their own food through photosynthesis using sunlight, water, and carbon dioxide. They convert these raw materials into glucose, which serves as their energy source. This fundamental difference in nutrient acquisition is what distinguishes fungi from plants.

    Which organisms have calls without a nuclei?

    Correct Answer
    archaea
    Explanation
    Archaea are single-celled microorganisms that lack a true nucleus. They have a simple cellular structure and are considered to be one of the oldest forms of life on Earth. Unlike eukaryotes, archaea do not have a membrane-bound nucleus to house their genetic material. Instead, their DNA is located in the cytoplasm. This characteristic distinguishes them from other organisms, such as bacteria and eukaryotes, which have cells with nuclei. Therefore, archaea are the organisms that have cells without a nucleus.
