Answer: Positive feedback loop
Explanation:
Even before the food reaches the stomach (before ingesting it), the glands of the stomach mucosa begin to release its gastric secretion. The main characteristic of this secretion is acidity, as measured by pH (one of the physiological variables).
This acidity is a result of the presence of hydrochloric acid, which is part of the secretion composition. In addition to it, water, pepsinogen (which will give rise to the enzyme pepsin) and the intrinsic factor. The acid has a function of the protection of the entire system by eliminating microorganisms. It is also responsible for the activation of pepsin (which only occurs with acid pH), the enzyme that digests proteins containing the amino acids leucine or phenylalanine or tryptophan or tyrosine.
The concept of Positive feedback loop states that the body tries to increase the value of a variable (acidity, in the case of pepsinogen) when it is below its optimal value (called a point adjustment) and decreases this value when it is above optimal.

Answer:
Gneiss
Explanation:
Quartzite and Hornfels are both non-foliated metamorphic rocks. Slate is foliated but is fine-grained, which leaves us with Gneiss, which is a foliated, coarse-grained metamorphic rock

the corn plants one is GMO's
and the dog one is cloning
The ventricles can cause ventricular tachycardia, a rapid dysrhythmia with heart rates of 100 to 250 per minute.
<h3>What is ventricular heartbeat?</h3>
Extra heartbeats known as premature ventricular spasms (PVCs) start within one of the brain's two lower pump chambers (ventricles). The normal pulse rhythm is disrupted by these extra beats, which can occasionally make the chest feel as though it is fluttering or skipping beats.
<h3>What is a normal ventricular?</h3>
The heart's left ventricle serves as its primary pumping chamber. It forces air blood up into the aorta, the main artery in your body, to supply the rest of your body. Based on the American Heart Association, a typical ejection fraction ranges from 50% to 75%. An ejection fraction that is on the edge can be from 41% and 50%.
