Which of the following statements is a false or incorrect statement?

a) damage to the visual association area can result in blindness
b) damage to the primary auditory cortex results in the inability to interpret pitch, loudness, and location
c) damage to the promoter cortex results in loss of motor skills programmed in that area but movement is still possible
d) damage to the primary motor cortex results only in the loss of both voluntary muscle control and reflexes

The correct answer is option d) "damage to the primary motor cortex results only in the loss of both voluntary muscle control and reflexes".

Explanation:

It is false that damage to the primary motor cortex results only in the loss of both voluntary muscle control and reflexes. Many people that suffer from brain damage by strokes suffer from primary motor cortex damage. This damage not only affects voluntary muscle control and reflexes, as it affects muscles movement of any kind and can affect coordination as well.

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
