What do holes in volcanic rock illustrate about the conditions in which it was formed??
Rufina [12.5K]
Some magma, which is called lava when it reaches the earth’s surface, is shot high into the air from pressure and gasses that accompany many eruptions. The air cools the magma and hardens it while it still contains the gasses that were present in the magma as bubbles. The resulting rock is filled with an infinity of holes which were once gas bubbles in the airborne lava.
Explanation:

The most straightforward thanks to making a case for this can be as a result of some volcanic rocks (pumice specifically) are actually rock foam. like several artificial foams, it's created once an extremely viscous soften fluid at air mass is violently depressurised and cold, avoiding the liquid kind to settle in a very compact condition. The holes, as in any foam or sponge, are empty as a result of on the first liquid kind they were full of gasses. once an activity, those gasses left the rock and therefore the cavities are full of air.

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.
