Natural selection, if only the best make it the gene pool will have stronger sheep and those sheep breeding will cause even stronger sheep
Answer:
ocular lenses (earpieces) use for imaging.
Answer:
a discovery by a human being
Explanation:
The correct answer would be a discovery by human being.
Penicillin existed in nature and was only discovered, albeit accidentally, by Alexander Fleming.
It is different from<u> technological innovation because the latter requires the synthesis of products that are not in existence already or improvement on a product that has been created before</u>.
Discovery is also different from advancement in technology. <u>The latter refers to the process of inventing, innovating, and spreading technological processes in society.</u>
Discoveries are usually natural and are not in any way an invention. However, advancement in technology can aid discoveries.
<span>Natural selection is a process by which organisms that are better adapted to their environment tend to C. evolve new traits. Evolution is a process of change through time. There are several mechanisms of evolution, such as natural selection, mutations, migrations, and genetic drift. Natural selection is the mechanism by which species adapt to their environment to increase their chance of survival and reproduction. It can result in progress and cause some organisms to evolve new traits they need. </span>
Assuming that the rest of the genome is normal, cells with an inactivating mutation in one copy of a tumor-suppressor gene with the second copy of the gene still wild-type are most likely to show no changes in DNA sequence.
Tumor suppressor genes are normally present in the body. These function properly and keep processing the cell growth and cell death (apoptosis). It can also suppress tumor development. If both copies of a tumor suppressor gene is mutated then only it cause a change in cell growth and form a tumor. So these are recessive in nature. And if only one gene is mutated then it shows no mutation. When a tumor suppressor gene is inactivated by mutation, the protein it encodes is not produced or does not function properly, and as a result, uncontrolled cell division can occur. Such mutations can contribute to the development of cancer.
