Roman55 [17]

Answer:

A) rely on protection and resources supplied from the maternal plant.

Explanation:

The embryo is a structure formed after the fusion of the male gamete and female gamete. A diploid zygote is formed after cellular division forms the embryo in the female gametophyte and therefore is considered the diploid tissue.

The embryo requires the nutrients for growth and absorb them from the surrounding female gametophyte structure like endosperm in the angiosperm. The embryos grow and form the sporophytic structure.

Thus, Option-A is correct.

Mother is Dd (has to be because one child has the disease)

Parents cross is dd x Dd which gives rise to Dd (0.5) and dd (0.5). Each time they have a child they have a 50% chance of the child having the disease. In their case, only one of their 3 children is dd. The others though are carriers!

morpeh [17]

Answer:

Option B

Explanation:

B. The cell will grow uncontrollably and continue to divide as long as it has food.

Cell growth is theeoretically stimulated by the binding of growth factors to their receptors using signaling pathways.

These pathways are regulated by proteins which are encoded for in the genes.

The gene that controls the regulation of these pathway when mutated produce malfunctioning signaling protein thus not allow for regulations of the cell cycle causing uncontrollable cell division. These mutated genes are called oncogenes.
