Explanation:
There are several ways the body responds to stress but one method used by psychologists to measure this response is Hans Selye's general adaptation syndrome. This occurs in 3 stages:
1. The alarm reaction. This occurs when the stressor is first presented resulting in the RELEASE OF HORMONES from the adrenal gland into the blood stream. The hormone in turn cause sympathetic nervous system activation and increase energy levels, INCREASE RESPIRATION, increase muscle tension, reduce sensitivity to pain, slow down the digestive system, and cause a RISE IN BLOOD PRESSURE.
2. The stage of resistance- this occurs till the stress is removed.
3. The stage of exhaustion
"It converts the inactive enzyme pepsinogen into the active enzyme pepsin, which is responsible for digesting proteins in your stomach. HCL also helps digest other foods in your stomach. Ultimately, HCL is neutralized by chemicals secreted in your small intestine."
But, use your own words, though. Because I just hit copy & paste. Hope this helps!

Energy is decreasing by 500 because some of it is turned into heat energy.
Explanation:
when an animal/creature consumes another living thing and or something that has energy it is decrease to a certain amount because some of the energy that the original animal/creature had is turned into heat energy because they use some of the energy for themselves to survive and live.
For example:
A flower is a producer because it produces energy and gets it gets eaten by a deer and some energy gets changed to heat and the other is consumed by the consumer (the deer) and so on.
<h2>Gelatin </h2>
Explanation:
Gelatin is a differential medium which tests the ability of an organism to produce an exoenzyme, called gelatinase (this enzyme hydrolyzes gelatin)
When gelatin is at a temperature below 32°C (or within a few degrees thereof), it is a semisolid material and at temperatures above 32°C, it is a viscous liquid
When gelatin is broken down, it can no longer solidify and if an organism can break down gelatin, the areas where the organism has grown will remain liquid even if the gelatin is refrigerated
No the conclusion by student is not right because the tube must be runny after incubation followed by refrigeration to be considered gelatinase positive
