Pairs of Unit Factors, or Genes
Mendel proposed that paired unit factors of heredity were transmitted faithfully from generation to generation by the dissociation and reassociation of paired factors during gametogenesis and fertilization, respectively. After he crossed peas with contrasting traits and found that the recessive trait resurfaced in the F2 generation, Mendel deduced that hereditary factors must be inherited as discrete units. This finding contradicted the belief at that time that parental traits were blended in the offspring.
A gene is made up of short sections of DNA that are contained on a chromosome within the nucleus of a cell. Genes control the development and function of all organs and all working systems in the body. A gene has a certain influence on how the cell works; the same gene in many different cells determines a certain physical or biochemical feature of the whole body (e.g., eye color or reproductive functions). All human cells hold approximately 21,000 different genes.
Genetics is the science of the way traits are passed from parent to offspring. For all forms of life, continuity of the species depends upon the genetic code being passed from parent to offspring. Evolution by natural selection is dependent on traits being heritable. Genetics is very important in human physiology because all attributes of the human body are affected by a person’s genetic code. It can be as simple as eye color, height, or hair color. Or it can be as complex as how well your liver processes toxins, whether you will be prone to heart disease or breast cancer, and whether you will be color
Connective tissues support the tissues of the mucosa and connect it to the muscularis layer.
The blood supply of the submucosa provides nutrients to the wall of the stomach. Nervous tissue in the submucosa monitors the contents of the stomach and controls smooth muscle contraction and secretion of digestive substances.
<h3>What is the function of the stomach?</h3>
The stomach secretes acid and enzymes that digest food. Ridges of muscle tissue called rugae line the stomach.
The stomach muscles contract periodically, churning food to enhance digestion. The pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.
Thus, this could be the answer.

Answer:
Pacific Northwest
Explanation:
In the United States, the Pacific Northwest is the region that receives the least thunderstorm in a year. This is because of the location of the region. The region consists of states like Washington, California, Alaska, Hawaii, and Oregon. This region has few thunderstorms due to the nature of the region. The coldness of the pacific ocean means that there is more colder air on the earth. This suppressed the hot air. Thus, conventional rainfall; with thunder is less common. The other factor is the dryness of the region. The dry region has a lower humidity. This lesson the chance of charges air between the two fronts.
