Answer:
Biologists measure the number of trophic levels in an ecosystem so as to check its stability and health.
Explanation:
Trophic levels are the feeding position in a food chain such as primary producers, consumers, etc. They are positions that an organisms occupies in a food chain (series of steps in which organisms transfer energy by eating or being eaten);- what it eats and what eats it.
Theoretically there is no any limit to the number of trophic levels in a food chain or number of organisms that live on each level.
Polarity- Epithelium is arranged so there is one free surface (apical surface) and one attached surface (basal surface)
Cellular nature– Cells in epithelium fit closely together side by side and sometimes atop each other to form sheets of cells.
Answer:
False.
Explanation:
NADP does not convert testosterone to estradiol. This oxidation is done by a steroid 17-a-hydroxysteroid dehydrogenase.
This oxidation is essential for stability of hormone: it helps to regulates the elevation of Testosterone in women,subduing the manifestation of male sexual characteristics,
and
for preventing autoimmune diseases.
<u>The oxidation involved two basic steps of reaction, controlled by two different enzymes.</u>
<u>NADP is a Co- factor, when in reduced form( NADPH) is used in Calvin cycle, of light independent reaction of photosynthesis, and in Nucleic acid and triglycerides synthesis</u>.
It has nothing to do with conversation of Androgen( testosterone to Estradiol.
