An example of codominance in humans would be hair texture, and let's assume a father with curly hair has children with a mother with straight hair:
The children that are a result can inherit straight, wavy, or curly hair.
Straight and curly haired children are homozygous bevause they are of the parental phenotype, and wavy haired children are heterozygous because they have a independent phenotype that represents both parents in a way.
Answer:
increased; almost 100%
Explanation:
The peppered moth witnessed a change in its color and the number at the end of the eighteenth century. The reason behind this was the Industrial Revolution that led to an increase in air pollution. With the increase in air pollution, the dark-colored moths increased in the number. Later, when air pollution decreased, the light-colored moths started to predominate. It was in 1895 that the number of dark-colored moths increased to the maximum.
C. pancreas
Its a gland near the stomach which secretes a fluid into the duodenum to help with food digestion. The fluid contains protease, carbohydrase and lipase, which breaks down larger molecules into smaller pieces. The pancreas also produces the hormones insulin and glucagon which regulate blood sugar. These hormones are released into the cardiovascular system.
Carbon dioxide is generated in tissues as a byproduct of normal metabolism. It dissolves in blood plasma to form carbonic acid (H2CO3); red blood cell (RBC) carbonic anhydrase catalyzes this reaction. Carbonic acid then spontaneously dissociates to form bicarbonate (HCO3−) and a hydrogen ion (H+). In response to the decrease in intracellular <span>pCO2</span>, more CO2 passively diffuses into the cell.
Cell membranes are generally impermeable to charged ions (i.e. H+, HCO3− ) but RBCs are able to exchange bicarbonate for chloride using the anion exchanger protein Band 3. Thus, the rise in intracellular bicarbonate leads to bicarbonate export and chloride intake. The term "chloride shift" refers to this exchange. Consequently, chloride concentration is lower in systemic venous blood than in systemic arterial blood: high venous pCO2 leads to bicarbonate production in RBCs, which then leaves the RBC in exchange for chloride coming in.<span>[2]</span>
