<span>s that a single on off switch can control the whole cluster of functionally related genes; these genes are coordinately controlled (ex: when Ecoli must make tryptophan for itself because the nutrient medium lacks this amino acid all the enzymes for the metabolic pathway are synthesized at one time)</span>
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

second one:when the thyroid produces too many hormones
Explanation:
I donno of its correct but I think its this
thanks fr points
have a gr8 day★:)
Answer:
Usually, no.
Explanation:
Normally, certain organisms and populations have already adapted to their respective environments. If you take that organism out of its preferred habitat and put it in an environment completely new to it, it would most likely die; in addition, the same biomes on different parts of the world even have slightly different organisms and amount of vegetation covering it.
Alcoholic fermentation and indeed most forms of fermentation are low-energy producing. The waste products are often medium-sized hydrocarbons/alcohols that, when fully oxidized to carbon dioxide provide more energy.
Cells ferment sugars to lactic acid B. During training. This is why your muscles are sore and sore during exercise. Essentially, building this lactic acid causes your muscles to scream for oxygen and use a simplified fermentation process to meet their energy needs, which is not efficient at all.
Yes, animals will ferment for a short time if they are not supplied with enough oxygen. Humans perform lactic acid fermentation when the body urgently needs a lot of energy. If you sprint as fast as you can, your cells only have a few seconds of ATP stored. When stored ATP is depleted, muscles begin to produce ATP through lactic acid fermentation.
