Answer:
The chance of having a Child who is a Heterozygote is 50% , The chance of having a child that will completely come down with Alpers syndrome is 0%
Explanation:
Jack has a history of Alpers in his family
Jill has no history
lets assume Jack is a carrier : Ab ( because that is how he could have survived the first 10 lethal years )
Jill : AA
Therefore the probability/chance of Jack and Jill having a child with Alpers ( carrier ) syndrome will be 50 % as shown below
AA * Ab = AA , Ab, AA, Ab
The child produced by Jack and Jill will only be a carrier of the syndrome and not completely affected by the syndrome
Geological change will not cause a mass extinction, because it happens on a too big scale - on the scale of millions of years. During such long time, it is more likely that other causes will influence the survival of extinction of species, such as climate change or environmental disasters, and even if there is a small influence, it would not be significant next to other causes.
Answer: The cell membrane invaginates and pinches off, creating a vesicle within the cell.
Explanation:
Endocytosis is an active transport mechanism, for particules to be transported, the plasma membrane of the cell invaginates, forming a pocket around the target particle. The pocket then pinches off, resulting in the particle being contained in a newly created intracellular vesicle formed from the plasma membrane.

Answer:
After mitosis is over, each of the daughter cells continues its separate life.
Explanation:
One or both can be started or continued through differentiation, ie. processes that give different cells special structures and functions. A cell destined to become a nerve cell moves in one way of differentiation, and a cell destined to be a muscle cell moves in another.
A variation of this mechanism involves a special type of cell called a stem cell. The stem cell divides by mitosis, whereby one daughter cell remains the stem cell and continues to divide again and again, while the other difference in certain cell peaks is determined in the tissues.
