SCNT stands for Somatic Cell Nuclear Transfer. It is used for creating an ovum with a donor nucleus. It can be useful in embryology and a donor nucleus.
The steps of SCNT are as following:
<span>d. Isolate donor cells from egg donor and germ cell donor
</span><span>c. Remove and discard the nucleus from the egg cell
</span><span>e. Transfer the somatic cell nucleus into the egg cell
</span><span>a. Stimulate cell division
</span><span>f. Implant embryo into a surrogate mother
</span><span>b. Deliver baby</span>
D.
It produced reproductive cells.

Answer:
Gonadotropins are polypeptide hormones and are secreted by the anterior pituitary gland.
Explanation:
Hypothalamus releases GnRH i.e gonadotropin releasing hormone which stimulates the anterior pituitary to secrete gonadotrophs such as FSH, ICSH and LH.
FSH (follicle stimulating hormone): In males it stimulates spermatogenesis. In females it stimulates growth of ovarian follicles.
ICSH (Interstitial cell stimulating hormone): In males, secretion of testosterone.
LH (Luteinising hormone): In femalestogether with FSH, it triggers ovulation, stimulates conversion of broken ovarian follicle into corpus luteum.

Answer:
Explanation:
A. False - A symporter system requires that one of the molecules to be transported using passive transport.
B. True - The Na+ will move down the established concentration gradient releasing energy to facilitate movement of sucrose against its concentration gradient. This is known as secondary active transport.
C. False - sucrose moves through ion channels not by diffusion to better control its movement across the membrane.
D. True - Movement of molecules against their concentration gradient thus requiring energy input is known as active transport.
E. False - One of the molecules needs to be moving against its concentration gradient.
F. False - A Uniporter system allows the binding and transport of a single molecule at a time. A symporter allows simultaneous binding and transport of Na+ and sucrose molecules.
