,Question: A population of rabbits in a forest is being
studied. The researchers notice that the population size has
increased significantly over the past year. What could be a
plausible explanation for this increase?
A. Decreased availability of food sources
B. Introduction of a new predator in the forest
C. Decrease in the prevalence of disease among the
rabbits
D. Loss of habitat due to deforestation
Answer: C. Decrease in the prevalence of disease among
the rabbits
Rationale: A decrease in disease prevalence would lead
to higher survival rates, resulting in an increase in
population size.
Question: Which of the following is an example of an
autotroph?
A. Lion
B. Mushroom
C. Oak tree
D. Human
Answer: C. Oak tree
Rationale: An autotroph is an organism that can produce
its own food using light or chemical energy. Oak trees are
an example of autotrophs as they undergo photosynthesis to
produce their own food.
, Question: During which phase of mitosis do the sister
chromatids separate and move towards opposite poles of
the cell?
A. Prophase
B. Metaphase
C. Anaphase
D. Telophase
Answer: C. Anaphase
Rationale: Anaphase is the stage of mitosis during which
the sister chromatids separate and move towards opposite
poles of the cell, ensuring that each daughter cell receives a
full set of chromosomes.
Question: What is the primary function of the Golgi
apparatus in a eukaryotic cell?
A. Protein synthesis
B. Lipid production
C. Energy production
D. Packaging and modification of proteins
Answer: D. Packaging and modification of proteins
Rationale: The Golgi apparatus is responsible for
receiving, packaging, and shipping proteins to various parts
of the cell and beyond.
Question: Which of the following best describes the
function of the enzyme amylase?
A. Breaks down proteins into amino acids
B. Catalyzes the breakdown of starch into sugars
