Answer:
The types of epithelia are classified by the shapes of cells present and the number of layers of cells
Explanation:
Environmental contamination reduces total testosterone oxido-reductase activity in females.- <u>True</u>
Enzymes are proteins which catalyze reactions by acting on substrates in order to speed up reactions- like the breakdown of large polysaccharides by amylase. Here, the enzyme testosterone oxi-reductase facilitates the of testosterone to the androgen DHT. Enzyme specificity is affected by pH, temperature and the presence of inhibitors.
In temperatures beyond its optimal range, these may undergo changes to its physical structure called denaturation; when denatured, enzymes lose their ability to bind specifically to their substrate -i.e. substrate binding specificity is lost. Testosterone would no longer be able to bind to the active site, and thus would not be converted.

Answer:
i think it's C, but I'm not sure
Seedless plants produce spores.Spores can develop into an adult without fusing with another cell.Seed plants produce seeds.Seeds are formed when the female reproductive structure matures; this occurs after fertilization.
That is the answer (:
