What conditions are possible reasons for declining genetic diversity of a species? Select all correct answers.
yan [13]

Some conditions that are possible reasons for declining genetic diversity of a species;

▪︎loss of habitat

▪︎inbreeding

Explanation:

Loss of habitat will definitely reduce diversity because it reduces the population size from increased competition for reduced resources. Some subspecies may be completely eliminated when their niche is completely lost.

Inbreeding also reduces diversity because it results in the expression of recessive genes in a population that are mostly disadvantageous. High inbreeding rates will result in most individuals not reaching maturity to pass down their genes to the next generations.

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.

What is the role of oceans in the carbon cycle?
Maslowich

Answer:

Don't worry I'm here to help

Explanation:

The ocean plays an important part in the carbon cycle.

  • Overall, the ocean is called a carbon 'sink' because it takes up more carbon from the atmosphere than it gives up.
  • Photosynthesis by tiny marine plants (phytoplankton) in the sunlit surface waters turns the carbon into organic matter.
