Answer:
The activity of speed up the process.
Explanation:
Reverse transcriptase is an enzyme encoded from the genetic material of retroviruses that accelerate or speed up the process of transcription of retrovirus ribonucleic acid into deoxyribonucleic acid. Reverse transcriptase enzyme is also called RNA-directed DNA polymerase. Some retroviruses such as human immunodeficiency virus (HIV) and avian myeloblastosis virus used this Reverse transcriptase enzyme.

A normal heart rate ranges between 60-100 beats per minute. The higher the heart rate is, the faster the blood is pumping through the heart. When exercising a persons heart will be higher because the brain and the muscles in the body are in need of oxygen so the heart needs to pump faster in order to sustain optimal performance.<span />
Dominant trait<span> definition. In genetics, a </span>trait<span> that will appear in the offspring if one of the parents contributes it. (Compare recessive </span>trait.) Note: In humans, dark hair is a dominant trait; if one parent contributes a gene for dark hair and the other contributes a gene for light hair, the child will have dark hair ...Recessive traits<span> can be carried in a person's genes without appearing in that person. For example, a dark-haired person may have one gene for dark hair, which is a dominant </span>trait<span>, and one gene for light hair, which is </span>recessive<span>.
