Trivia Quiz On Living Organisms - Quiz

Quiz Preview

  • 2. 

    Living organisms contain which of the following elements?

    • Cl, H, O, and N

    • C, He, O, and N

    • C, H, Os, and N

    • C, H, O, and N

    Correct Answer
    A. C, H, O, and N
    Explanation
    Living organisms contain the elements carbon (C), hydrogen (H), oxygen (O), and nitrogen (N). These elements are essential for the structure, function, and metabolism of living organisms. Carbon is the backbone of organic molecules, hydrogen and oxygen are important for energy production and water balance, and nitrogen is necessary for the synthesis of proteins and nucleic acids.

    The first living organisms were

    • Viruses

    • Unicellular

    • Multicellular

    • Early

    Correct Answer
    A. Unicellular
    Explanation
    The correct answer is unicellular. This is because the first living organisms were believed to be unicellular, meaning they were composed of a single cell. These early organisms were simple in structure and function, lacking the specialized cells and complex organization found in multicellular organisms. Unicellular organisms, such as bacteria and archaea, were able to carry out the necessary functions of life, such as reproduction and metabolism, within a single cell. Over time, multicellular organisms evolved from these unicellular ancestors through processes like cell specialization and differentiation.

    Homeostasis refers to

    • Energy used by all living organisms.

    • Maintaining a stable internal environment.

    • Requiring water to survive.

    • Occupying space.

    Correct Answer
    A. Maintaining a stable internal environment.
    Explanation
    Homeostasis refers to the ability of an organism to maintain a stable internal environment despite external changes. This includes regulating body temperature, pH levels, and nutrient concentrations within a narrow range. It involves various physiological processes such as feedback loops and hormone regulation to ensure optimal functioning of cells and organs. Energy usage, water requirement, and occupying space are not the primary definitions of homeostasis, making "maintaining a stable internal environment" the correct answer.

  • 5. 

    Which of the following is NOT a characteristic of all living organisms?

    • Having different cell types

    • Growth and development

    • Reacting to stimuli

    • Reproduction

    Correct Answer
    A. Having different cell types
    Explanation
    Having different cell types is not a characteristic of all living organisms because some organisms, such as bacteria, are unicellular and consist of only one type of cell. In contrast, multicellular organisms, like plants and animals, have different types of cells that perform specialized functions.

  • 6. 

    Organisms that produce their own food are called

    Correct Answer
    autotrophs.
    autotrophs
    Explanation
    Autotrophs are organisms that are capable of producing their own food through photosynthesis or chemosynthesis. They convert sunlight or inorganic substances into organic compounds that can be used as a source of energy. This ability to self-nourish distinguishes them from heterotrophs, which rely on consuming other organisms for their energy needs. Autotrophs play a crucial role in the food chain as primary producers, providing energy for other organisms. Examples of autotrophs include plants, algae, and some bacteria.

    Rate this question:

  • 7. 

    The earth's atmosphere originally consisted of which of the following?

    • He, water vapor, oxygen, and methane

    • He, N, oxygen, and methane

    • N, water vapor, oxygen, and methane

    • N, water vapor, carbon dioxide, and methane

    Correct Answer
    A. N, water vapor, carbon dioxide, and methane
    Explanation
    The correct answer is N, water vapor, carbon dioxide, and methane. This is because the Earth's early atmosphere was primarily composed of nitrogen (N), water vapor, carbon dioxide, and methane. Over time, through various geological and biological processes, the composition of the atmosphere has changed, with oxygen becoming more abundant due to photosynthesis by plants and other organisms.

    Rate this question:

  • 8. 

    Organisms that "go get" their own food are called

    Correct Answer
    heterotrophs.
    heterotrophs
    Explanation
    Heterotrophs are organisms that obtain their own food from external sources. They cannot produce their own food through photosynthesis or other means, so they rely on consuming other organisms or organic matter to meet their nutritional needs. This is in contrast to autotrophs, which can produce their own food. Therefore, the correct answer is heterotrophs.

    In Redi's experiment, the control was

    • The open jar.

    • The jar covered with netting.

    • The jar covered with a lid.

    • None of the above.

    Correct Answer
    A. The open jar.
    Explanation
    In Redi's experiment, the control was the open jar. The control group in an experiment is the group that is not exposed to the independent variable, in order to compare the results with the experimental group. In this case, Redi wanted to test the idea of spontaneous generation, so he set up three jars with meat: one open, one covered with netting, and one covered with a lid. By observing that maggots only appeared in the open jar, Redi was able to conclude that maggots do not spontaneously generate, but rather come from flies laying eggs on the meat.

    Rate this question:

  • 10. 

    The first living organisms could be found in

    Correct Answer
    oceans.
    oceans
    Explanation
    The first living organisms could be found in oceans. Oceans are vast bodies of water that cover a large portion of the Earth's surface. They provide a suitable environment for the development and sustenance of life due to their abundance of water, nutrients, and diverse ecosystems. Oceans offer stable temperatures, protection from harmful radiation, and a source of food for organisms. Additionally, the presence of water in oceans allows for various chemical reactions necessary for the formation of organic molecules and the evolution of life. Therefore, it is reasonable to believe that the first living organisms originated in oceans.

    Rate this question:

  • 11. 

    Please explain the difference between growth and development as it relates to living organisms.

  • 12. 

    Please explain why Redi's experiment is considered to be so important to the study of living organisms.
