Answer:
The correct answer will be- primary motor cortex
Explanation:
The motor cortex is the portion of the brain present in the precentral gyrus of the frontal lobe of the brain. The motor cortex is thought to be involved in the planning actions and control voluntary actions.
The motor cortex is divided into three regions: premotor cortex, primary motor cortex and supplementary motor area.
The primary motor cortex is the region of the motor cortex which controls the voluntary movements in the human body by generating the impulse.
Thus, the primary motor cortex is the correct answer.

About 93 million miles or 150 km or 8 light minutes (don't know what that means)
Natural selection act directly upon <u>Alleles</u>
Explanation:
Genes, such as that of fur color, have many variants called alleles. Natural selection act on the alleles and chooses the best fit for an environment and eliminates the disadvantageous ones from the population over generations. Mutations are a rare occurrence that increases the number of allelic variants of a genes on which natural selection can act upon.
Three
different ways the relatedness of species could be assessed is through:
<span>1.
</span>Their genotype. Similarity in DNA between the species is a good
indication of their relatedness.
<span>2.
</span>Their phenotype. If the two species have similar body form and function,
then there is a good possibility that they are related.
<span>The presence of intermediates, either living
or in the fossil record, can show relatedness between two species.</span>
