Answer:
Has three dominant alleles
Explanation:
Skin colour is a polygenetic inheritance and it is controlled by three genes pairs of alleles. The human skin is determined by the amount of melanin it contains. A combination of melanin producing alleles determines the skin color.
In the above question, the person has a skin color that is midway meaning only half of the alleles produced melanin. The total number of alleles is 6 and half of it is 3. So, only 3 alleles were dominant and the remaining three were recessive.
Answer:
The molecule on the right; the middle carbon is asymmetric
Explanation:
<span>Digestive enzymes are prolific inside the lysosomes. The organelle is named as such because these enzymes engage in "lysing" activity, meaning that the break up the worn-out cell parts or other wastes that the structure engulfs.</span>
Answer:
The primary means for transmitting messages between the brain and the rest of the body is the <u>spinal cord</u>.
Explanation:
The spinal cord is the main pathway of the nervous system. The impulses are transmitted to the brain through bundles of ascending nerve fibers, while the descending fibers transmit impulses in the opposite direction. Signals are transported to and from different parts of the body along the fibers of the pair of spinal nerves, which form intersections with the spinal cord through their dorsal and ventral roots; the sensory and motor fibers converge in the gray matter of the medulla.
