Answer:
The correct option is A.
Explanation:
TATA box refers to a non coding sequence of DNA that is found in the promoter regions of eukaryotic genes. The TATA box serves as the binding sites for certain proteins and some transcriptions factors in eukaryotic genes; it signifies the points where transcription begins. Transcription is the process by which the genetic information in DNA is replicated into an mRNA. This is the first step in protein synthesis. The name TATA was derived from the nucleotide bases that are always present in large number a the site. T stands for thymine while A represents the adenine base.
Exercise lowers modest amounts of blood glucose and boosts the body's sensitivity to insulin.
Blood glucose is the concentration of sugar dissolved in the blood of a person. It is the prime source of energy for the body. When the blood glucose is very high, the person is likely to be diabetic. Exercise is necessary to burn the excessive glucose molecules in order to gain energy for the exercise.
Insulin is a polypeptide which regulates the glucose levels in the body. It is secreted by the pancreatic cells called Islets of Langerhans. The structure is composed of two chains: A chain and B chain, joined together by the disulfide bonds.

Explanation:
Answer:
Because offspring with two parents will share half of each parent's DNA.
Explanation:
Sex cells contain half of the genetic information of an organism's regular cells. This is because a sexually-produced organism will be unique; it will share genetic information with both of its parents, rather than be identical to its bearer (like an asexual organism would be). When a sex cell meets another sex cell, their DNA will meet as well and change/adapt to suit the organism. If a sex cell had all the information needed to create an embyro, instead of half, which requires another cell's information to fill the DNA void.... well, it would just do it.
