Answer: adult tissues
Explanation: Adult stem cells. These stem cells are found in small numbers in most adult tissues, such as bone marrow or fat. Compared with embryonic stem cells, adult stem cells have a more limited ability to give rise to various cells of the body.

Based on the mutation rate of the molecular clock, it will take 22.5 million years for one full base pair mutation to occur.
<h3>What is a molecular clock?</h3>
A molecular clock is a biomolecule which is chosen to serve as a clock due to its periodical changes in a regular pattern.
Mutation in genes can serve as molecular clock.
The mutation in the gene of coding for the venom mutates at a rate of 0.76 base pairs every 17.1 million years.
It will take 17.1/0.76 = 22.5 million years for 1 base pair to mutate.
Therefore, it will take 22.5 million years for one full base pair mutation to occur.

The doctor likely suspects that the drug <u>
Diethylstilboestrol ( thalidomide)</u>
is behind Jackie's problems</h2>
Explanation:
Diethylstilboestrol, commonly known as DES or thalidomide was widely prescribed as an anti-miscarriage drug for 30 years between 1943 and 1973.
The production and sale of this drug was banned due to its carcinogenic side effects. It was also discovered that the effects of this drug can also manifest themselves in people whose mothers were administered with the drug.
If Jackie's mother consumed DES while she was pregnant with Jackie,, It is probable that Jackie's miscarriages and her cancer are an indirect effect of the banned drug.
The correct option is B.
Gene flow refers to the movement of genes from one population to another population. The movement of genes in and out of a particular population usually result in significant changes in the gene frequencies of the population members that are carrying specific variant of a particular genes. Thus leading to increase in the amount of genetic variations in that population.
