Questions and Answers
  • 1. 

    What is extinction?

    • A.

      The disappearance of every individual of a species form the entire planet

    • B.

      A local extinction, or the disappearance of a species from a particular area

    • C.

      Variation within species

    • D.

      Overspecialization

    Correct Answer
    A. The disappearance of every individual of a species form the entire planet
    Explanation
    Extinction refers to the complete disappearance of every individual of a species from the entire planet. This means that there are no remaining members of the species left anywhere in the world. Extinction can occur due to various factors such as habitat destruction, climate change, hunting, or natural disasters. It is a significant event as it signifies the permanent loss of a species and can have far-reaching ecological and environmental impacts.

    • A.

      I and III

    • B.

      I and IV

    • C.

      II and III

    • D.

      II and IV

    Correct Answer
    C. II and III
    Explanation
    The causes of species extinction that are most directly related to human activities are overharvesting (II) and loss of habitat (III). Overharvesting refers to the excessive hunting, fishing, or harvesting of species for commercial or personal purposes, leading to a decline in their population. Loss of habitat, on the other hand, occurs when human activities such as deforestation, urbanization, or pollution destroy or degrade the natural habitats of species, making them unable to survive. These two causes are directly linked to human actions and their impact on the environment.

    Rate this question:

  • 3. 

    A benefit of asexual reproduction is that it....

    • A.

      Produces many offspring

    • B.

      Increases genetic diversity

    • C.

      Increases species diversity

    • D.

      Requires specialized structures

    Correct Answer
    A. Produces many offspring
    Explanation
    Asexual reproduction is a type of reproduction that involves only one parent, and it produces offspring that are genetically identical to the parent. This method allows for the rapid production of numerous offspring, which is advantageous for the survival and proliferation of the species. By producing many offspring, asexual reproduction increases the chances of survival and successful colonization of new habitats. This is why producing many offspring is considered a benefit of asexual reproduction.

    Labrador retrievers have 78 chromosomes in each of their muscles. ------------------------------------------------------------------------------------------------ Which biological process ensures that a male Labrador retriever's sperm cells will each have 39 chromosomes?

    • A.

      Mitosis

    • B.

      Meiosis

    • C.

      Selective breeding

    • D.

      Artificial selection

    Correct Answer
    B. Meiosis
    Explanation
    Meiosis is the biological process that ensures that sperm cells in a male Labrador retriever (and in any other organism) will have half the number of chromosomes as the other cells in the body. During meiosis, the cells undergo two rounds of division, resulting in the production of four haploid cells, each containing half the number of chromosomes as the original cell. Therefore, in the case of a male Labrador retriever, which has 78 chromosomes in each of its muscle cells, meiosis will ensure that each sperm cell produced will have 39 chromosomes.

    Rate this question:

  • 5. 

    A plant that produced red flowers was mated with a plant that produced white flowers, the resulting offspring produced only red flowers. A conclusion that can be drawn from this experiment is that the white flower trait is...

    • A.

      Dominant and no longer part of the offspring's DNA

    • B.

      Recessive and no longer part of the offspring's DNA

    • C.

      Dominant and still part of the offspring's DNA

    • D.

      Recessive and still part of the offspring's DNA

    Correct Answer
    D. Recessive and still part of the offspring's DNA
    Explanation
    The conclusion that can be drawn from this experiment is that the white flower trait is recessive and still part of the offspring's DNA. This is because when the red flower plant was mated with the white flower plant, all the resulting offspring produced red flowers. This indicates that the red flower trait is dominant and masks the expression of the white flower trait. However, since the offspring still have the potential to produce white flowers in future generations, it means that the white flower trait is recessive and present in their DNA.

  • 6. 

    Which of the following heritable traits cannot be influenced by the environment?

    • A.

      Height

    • B.

      Weight

    • C.

      Skin colour

    • D.

      Earlobe attachment

    Correct Answer
    D. Earlobe attachment
    Explanation
    Earlobe attachment is a heritable trait that is determined by genetics and cannot be influenced by the environment. It is determined by specific genes and is not affected by external factors such as diet, exercise, or environmental conditions. Height, weight, and skin color, on the other hand, can be influenced by a combination of genetic and environmental factors, such as nutrition, lifestyle, and exposure to sunlight.

  • 7. 

    What type of sexual reproduction is mitosis?

    • A.

      Asexual

    • B.

      Sexual

    • C.

      All of the above

    • D.

      None/ not listed

    Correct Answer
    A. Asexual
    Explanation
    Mitosis is a type of cell division that results in two daughter cells with the same genetic material as the parent cell. It is a form of asexual reproduction because it does not involve the fusion of gametes or the exchange of genetic material between two individuals. Instead, mitosis allows for the production of genetically identical offspring, making it a key process in the growth, development, and repair of multicellular organisms.

    What type of sexual reproduction is meiosis?

    • A.

      Asexual

    • B.

      Sexual

    • C.

      All of the above

    • D.

      None/ not listed

    Correct Answer
    B. Sexual
    Explanation
    Meiosis is a type of sexual reproduction. It is the process by which cells divide and produce gametes, such as eggs and sperm, with half the number of chromosomes as the parent cell. During meiosis, genetic material is shuffled and recombined, leading to genetic diversity in offspring. This process is essential for sexual reproduction as it allows for the exchange and mixing of genetic material between individuals. Therefore, the correct answer is sexual.

    Rate this question:

  • 9. 

    What is the number of divisions that occur in the process of mitosis?

    • A.

      1

    • B.

      2

    • C.

      4

    • D.

      0

    Correct Answer
    A. 1
    Explanation
    Mitosis is a type of cell division that results in two identical daughter cells. During this process, the cell undergoes a series of stages, including prophase, metaphase, anaphase, and telophase. The number of divisions that occur in mitosis is one, as the cell divides only once to produce the two daughter cells. Therefore, the correct answer is 1.

    What is the number of divisions that occur in the process of meiosis?

    • A.

      1

    • B.

      2

    • C.

      4

    • D.

      0

    Correct Answer
    B. 2
    Explanation
    In the process of meiosis, there are two divisions that occur. Meiosis is a type of cell division that produces gametes (sex cells) with half the number of chromosomes as the parent cell. The first division, called meiosis I, separates homologous chromosomes, resulting in two cells with half the number of chromosomes. The second division, called meiosis II, separates sister chromatids, resulting in four cells with the haploid number of chromosomes. Therefore, the correct answer is 2.

      Mutualism

    • C.

      Commensalism

    • D.

      Resource partitioning

    Correct Answer
    A. Parasitism
    Explanation
    Parasitism is the correct answer because it accurately describes the relationship between the tapeworm and the human. In parasitism, one organism (the tapeworm) benefits at the expense of the other organism (the human) by consuming its nutrients. This relationship is harmful to the human, as it deprives them of essential nutrients, while the tapeworm benefits by obtaining its necessary nutrients for survival.

    • A.

      Parasitism

    • B.

      Mutualism

    • C.

      Commensalism

    • D.

      Resource partitioning

    Correct Answer
    C. Commensalism
    Explanation
    Commensalism is a type of relationship where one organism benefits while the other is neither harmed nor benefited. In this scenario, the fish swim closely to the whale, potentially gaining protection from predators or using the whale as a source of food scraps. The seagulls, in turn, take advantage of the disturbance created by the whale to catch food. While the fish benefit from the whale's presence, the whale is not affected by their actions, making it an example of commensalism.

    • A.

      Binary fission

    • B.

      Budding

    • C.

      Spore production

    • D.

      Vegetative reproduction

    • E.

      Fertilization

    Correct Answer(s)
    A. Binary fission
    B. Budding
    C. Spore production
    D. Vegetative reproduction
    Explanation
    The four types of asexual reproduction are binary fission, budding, spore production, and vegetative reproduction. Binary fission is the division of a single organism into two equal parts. Budding is the formation of a new organism from an outgrowth or bud on the parent organism. Spore production involves the production and release of reproductive cells called spores, which can develop into new organisms. Vegetative reproduction is the process of producing new individuals from non-reproductive parts of the parent organism, such as stems or roots. Gamete cells and fertilization are not types of asexual reproduction, as they involve the fusion of male and female reproductive cells to produce offspring.

      Budding

    • C.

      Spore reproduction

    • D.

      Vegetative reproduction

    Correct Answer
    C. Spore reproduction
    Explanation
    This is not spore reproduction. Spore reproduction involves the production and release of spores, which are single-celled reproductive structures that can grow into new individuals. In this scenario, the parent plant produces several offspring that are identical to the parent, which is characteristic of vegetative reproduction. Vegetative reproduction involves the growth and development of new individuals from vegetative parts of the parent plant, such as stems, leaves, or roots.
