What factors are contributing to the oceans changing ph ?
ddd [48]
Because of human-driven increased levels of carbon dioxide in the atmosphere, there is more CO2 dissolving into the ocean. The ocean's average pH is now around 8.1 , which is basic (or alkaline), but as the ocean continues to absorb more CO2, the pH decreases and the ocean becomes more acidic.

Aldosterone is synthesized from cholesterol. <br> a. True<br> b. False
patriot [66]

Answer:

The correct answer is A. Effectively, aldosterone is synthesized from cholesterol.

Explanation:

Aldosterone is a steroid hormone from the mineralocorticoid family, synthesized in the glomerular area of the adrenal cortex of the adrenal gland. It acts in the conservation of sodium, in the secretion of potassium and in the increase of blood pressure. Its secretion is decreased in Addison's disease and increased in Conn's syndrome. Aldosterone, as well as all steroid hormones, is synthesized from cholesterol.

Gene S controls the sharpness of spines in a type of cactus. Cactuses with the dominant allele, S, have sharp spines, whereas ho
Leviafan [203]

Answer:

Sharp-spined cactus

Explanation:

Given, that N allele is required for the production of spine and S allele will produce sharp sines.

True breeding sharp spined cactus: NNSS

spineless cactus: nn__ ( we can't fix the allele for second gene since it has not been mentioned as true breeding )

Their progeny: NNSS X nn__ = NnS_

So the progeny is going to be sharp spined because both the dominant alleles N and S are present.
