it's going to be called nucleotides
The answer is “Variation that decrease reproductive success are more likely to be passed on.”
Antigens; they are molecules that are foreign to the body, thus stimulating a response by the b- and t-cells that aim to defend the body against harmful and mostly foreign bacteria.
Answer:
The amount of mass that planet Jupiter has in the solar system makes it approximately five times larger than all other planets in it. As Jupiter’s gravity pulled on another planet tightly, its diameter grew and it expanded. The density and gravity continued to increase, resulting in even more planet compression.
Explanation:
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.
