  • 2. 

    [Another name for living things is organisms] true or false?

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Living things and organisms are synonymous terms used to describe entities that possess the characteristics of life, such as the ability to grow, reproduce, and respond to stimuli. Therefore, it is correct to say that another name for living things is organisms.

    A bird fluffs its feathers to trap body heat to keep warm during winter months. This is an example of: 

    • Homeostasis

    • Homeopathy

    • Spontaneous generation

    • Asexual reproduction

    Correct Answer
    A. Homeostasis
    Explanation
    The bird fluffing its feathers to trap body heat is an example of homeostasis. Homeostasis refers to the ability of an organism to maintain a stable internal environment despite changes in the external environment. In this case, the bird is regulating its body temperature by adjusting its feathers to retain heat and prevent heat loss. This helps the bird to survive and stay warm during the winter months.

    [In sexual reproduction, offspring are different from the parent] true or false?

    • True

    • False

    Correct Answer
    A. True
    Explanation
    In sexual reproduction, offspring are different from the parent because they inherit a unique combination of genes from both parents. This genetic variation is a result of the process of meiosis, where the genetic material is shuffled and recombined during the formation of gametes. This variability is important for the survival and adaptation of species, as it allows for the potential emergence of advantageous traits and the ability to respond to changing environments.

    Which of the following terms best describes green plants?

    • Muticellular heterotrophs

    • Multicellular autotrophs

    • Unicellular autotrophs

    • Unicellular heterotrophs

    Correct Answer
    A. Multicellular autotrophs
    Explanation
    Green plants are multicellular organisms that are capable of producing their own food through the process of photosynthesis. They contain chlorophyll, which gives them their green color and allows them to convert sunlight into energy. As autotrophs, they do not rely on consuming other organisms for nutrition. The term "multicellular autotrophs" accurately describes green plants as they are made up of multiple cells and can produce their own food.

    [Organisms break down and build up materials in a process called metabolism] true or false?

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Metabolism is the process by which organisms break down and build up materials. It involves various chemical reactions that occur within cells to convert nutrients into energy and essential molecules needed for growth, repair, and maintenance of the body. Therefore, the statement "Organisms break down and build up materials in a process called metabolism" is true.

    The one factor that a scientist changes in an experiment is called the...

    • Responding variable

    • Hypothesis

    • Controlled variable

    • Manipulated variable

    Correct Answer
    A. Manipulated variable
    Explanation
    The manipulated variable is the one factor that a scientist intentionally changes or manipulates in an experiment. This variable is deliberately altered to observe its effect on the responding variable, which is the outcome or result of the experiment. The other variables in the experiment, such as the controlled variables, are kept constant to ensure that any changes in the responding variable can be attributed solely to the manipulated variable.

    [Bacteria, the most numerous organism on Earth, are multicellular organisms] true or false?

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Bacteria are actually unicellular organisms, not multicellular. They are microscopic in size and consist of a single cell. This allows them to carry out all necessary functions for survival and reproduction within a single cell. Therefore, the statement that bacteria are multicellular organisms is false.

    Rate this question:

  • 9. 

    Which of the following is NOT a chemical of life?

    • Mineral

    • Water

    • Nucleic acid

    • Carbohydrate

    Correct Answer
    A. Mineral
    Explanation
    Minerals are inorganic substances that are not considered chemicals of life. While water, nucleic acids, and carbohydrates are all essential components of living organisms, minerals are not directly involved in the biochemical processes of life. They are important for various bodily functions, but they are not considered chemicals of life in the same way that the other options are.

    Is [The process of change during an organism's life that results in a more complex growth is called growth ] true or false?

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The statement is false because the process of change during an organism's life that results in a more complex growth is actually called development, not growth. Growth refers to an increase in size or mass of an organism, while development refers to the changes in form, structure, and function that occur as an organism matures.
