Explanation:
Reflexes do slow with age. Physical changes in nerve fibers slow the speed of conduction. And the parts of the brain involved in motor control lose cells over time.
Researchers found that the brain's response time begins to decline at age 24. The descent is a slow, but nonetheless, steady one.
Answer:
The correct answer is a gene
Explanation:
The DNA segment that carries information for coding one protein or polypeptide is called a gene. According to one gene-one polypeptide hypothesis, each gene is responsible for making a single chain of the polypeptide.
Originally it was said that one gene codes for one enzyme but later it was found that some gene also codes for non-enzyme proteins and single polypeptide chains. So after this research, the theory was modified and one gene-one polypeptide theory came. Therefore the right answer is gene.
Answer:
b
Explanation:
other answers are incorrect because none of then except b makes sense
Answer:
40mm
Explanation:
each AABBCCDDEE = 55
each will contribute 55/5 = 11
thus, AaBBCcDDEe will be 5.5 + 11 + 5.5 +11 + 5.5 = 38.5, approx. 40mm
