Answer:

Fossil record is used to study macro evolution.

Explanation:

Macroevolution may be defined as the change above the species level.  Fossils are the impressions of dead plants and animals buried under the surface of rocks.

Fossils provide the direct evidence of macroevolution. For example : Paleozoic era was dominated by trilobites, crinoids and brachiopods. Rocks that one part of paleozoic era are now contains the fossils of trilobites, crinoids and brachiopods. These species may either extinct or not common in today's world. Thus, fossil record can be used to study macroevolution.

Why do the levels of GH-RH and CRH rise during the resistance phase of the general adaptation syndrome?
Alenkinab [10]

Answer:

During the resistance phase of the general adaptation syndrome, the human body undergoes a process of adaptation or tolerance to stress, which requires an increase in levels of growth hormone (GH) and cortisol, so it is observed rise the levels of GHRH and CRH.

Explanation:

General adaptive syndrome is a product of the stress to which an individual is subjected, causing a number of symptoms reflecting the loss of normal body balance, symptoms that can be both physical and psychological. This syndrome has three phases:

  • <em>Alarm phase. </em>
  • <em>Resistance phase. </em>
  • <em>Exhaustion phase. </em>

The second phase, resistance, is due to an <u>adaptation or tolerance when the stressful stimulus is maintained</u>. At this stage, an increase in blood levels of growth hormone and cortisol -which contribute to the stress tolerance process- is usually observed, increasing the bioavailability of blood glucose and endogenous steroids.

Both GHRH (somatocrin) and CRH (corticotropin-releasing hormone) are produced by the hypothalamus and activate the release of GH and adrenocorticopotrotrope hormone (CRH) by the pituitary gland, producing:

  1. <em>Increased levels of circulating growth hormone, necessary to regulate metabolism, and increase the amount of blood glucose. </em>
  2. <em>Increased levels of cortisol, from the adrenal glands, in response to stress.  </em>

In the resistance phase of general adaptative syndrome, GHRH and CRH levels increase to regulate adaptive changes that occur in the body of the individual who has it.
