Answer:
This question lacks options, the complete question is: What do you think would have the greatest effect on the body—a harmful mutation in a pluripotent embryonic stem cell, or a harmful mutation in an adult multipotent stem cell?The correct answer is a harmful mutation in a pluripotent embryonic stem cell.
Explanation:
Pluripotent Stem Cells can self-renew and differentiate into any of the three germ layers, which are: the ectoderm, the endoderm and the mesoderm. These three germ layers subsequently differentiate to form all the tissues and organs within a human being. If during embryonic development, genetic mutations - alterations in genes - occur in the embryonic stem cell, they pass to daughter cells as a consequence of cell division, and an individual is generated whose cells differ at the genetic level. Multipotent stem cells are organospecific cells, that is, they can give rise to any type of cells but from a specific organ (a lung, a kidney or the brain). Their differentiation ends the moment they specialize and become a cell with a specific function within a specific tissue or organ. If there were a mutation in these cells, it would damage a specific designed tissue or organ.
Complete Question:
Which of the following hormones is released by the anterior pituitary as a part of that positive feedback loop between it and the ovary?
A) progesterone
B) luteinizing hormone
C) gonadotropin releasing hormone
D) estrogen
E) gonadotropin
Answer: luteinizing hormone (Option B)
Explanation: Luteinizing hormone (LH) is a gonadotropic hormone secreted by gonadotropic cells in the anterior pituitary gland. Luteinizing hormone (LH) performs series of functions when secreted. For example, LH triggers corpus leteum development (which produce progesterone for pregnancy sustainance) and ovulation in females when at acute rate.
However, low rate of luteinizing hormone (LH) establish signs of primary ovarian failure (a feedback mechanism) which translates that the ovaries have problem.
Make a paraffin block with that wing present inside. Now make fine slices of that block. Take one fine & even slice on a slide & then stain it.
Hope this helps you!
Answer:
ATP levels would fall at first, decreasing the inhibition of PFK and increasing the rate of ATP production.
