First you need to add all the fractions you know. 3/12 + 1/12 = 4/12. Then you subtract your answer of 4/12 to 1/2. But you first need a common denominator. A common factor is 12 for example. 4/12 stays the same, but 1/2 becomes 6/12. 6/12, or 1/2 minus 4/12 is 2/12. Your answer is 2/12 or B.
Answer:
water is absorbed by the embryo, which results in the rehydration and expansion of the cells.
Explanation:
Mutations occur in both germ cells and somatic cells, but the consequences of both are different. Mutations in somatic cells are called somatic mutations. In this case, if mutations occur in somatic cells, they can develop diseases, or start the cancerous process. They give rise to all non-germ line tissues because they do not occur in cells that give rise to gametes.
In addition to this, a process known as teratogenesis may occur, which may end up with congenital defects, disorders, and syndromes. During the process, genetic changes may cause alterations in the baby during the embryonic phase of the pregnancy.<span>

An approach to systematics in which organisms are placed into groups called clades based primarily on common descent. A group of species that includes an ancestral species and all its descendants. Pertaining to a group of taxa that consists of a common ancestor and all of its descendants. It is equivalent to a clade.
