Answer:
A. Nuclear reactors increase thermal pollution
Explanation:
From the analogy provided in this context, we can vividly see that the author is suggesting that the use of nuclear energy causes thermal pollution.
- Nuclear energy is an alternate energy source as identified in the text.
- Since a huge amount of heat energy is generated and they are not all used up, they are released into the ecosystem.
- The earth is usually depicted as heat reservoir.
- Increased release of heat to the environment will cause thermal pollution.
- This increases the ambient temperature of water and degrades it.
Answer:
Gonadotrophin
Explanation:
*GONADOTROPHINS:These are *hormones produced by the anterior lobe of the pituitary gland that regulate the male and female reproductive organ*. The two Gonadotrophins are *Follicle stimulating hormone(FSH) and Luteinising hormone(LH)*. Both are glycoproteins.
*Follicle stimulating hormone stimulates spermatogenesis by stimulating the sertoli cells to complete the development of spermatozoa from spermatids*.
*Luteinising hormone stimulates the synthesis of the hormone "testosterone" by the leydig (interstitial cells) of the testis*. Testosterone is a steroid hormone and is made from cholesterol, It stimulates growth and development of the germinal epithelial cells (spermatogonia) to form sperms,and also works with follicle stimulating hormone to stimulate sertoli cells.
The same principle apply to stereo microscopes, a 10X eye piece combined with a 4X objective lens will produce 40X magnification.
Its the barrier it proctects the cell and makes sure nothing goes in and nothing goes out
