Biology EOC Review

Front

What is the primary cause of genetic variation during meiosis?

Back

The primary cause of genetic variation during meiosis is the "crossing over" of chromosomes.

Front

What process adds carbon dioxide to the atmosphere?

Back

Carbon dioxide is added to the atmosphere by burning fossil fuels, cellular respiration, and decomposing organic matter. All answers are correct.

Front

What is the relationship called when red-billed oxpeckers feed on parasites infesting impala?

Back

This relationship is an example of mutualism.

Front

What percentage of offspring will be gray in incomplete dominance in cats?

Back

50% of the offspring will be gray.

Front

What is the source of energy for the contractile vacuole process in protists?

Back

The source of energy for this process is ATP.

Front

Define meiosis.

Back

Meiosis is a type of cell division that reduces the chromosome number by half, resulting in the production of gametes (sperm and eggs).

Front

What is the role of ATP in cellular processes?

Back

ATP (adenosine triphosphate) serves as the primary energy carrier in cells, providing energy for various biochemical reactions.

Front

Explain the concept of mutualism with an example.

Back

Mutualism is a symbiotic relationship where both species benefit. An example is the relationship between bees and flowering plants.

Front

What is incomplete dominance?

Back

Incomplete dominance is a genetic situation in which one allele does not completely dominate another allele, resulting in a phenotype that is a blend of the two.

Front

What is the function of a contractile vacuole?

Back

A contractile vacuole helps to eliminate excess liquid from a cell, preventing it from bursting.
