Answer:
The blood goes through an oxygenation process that is carried out by the blood vessels, the heart and the lungs, so if any of these structures is affected the entire circulation system will be altered. The circulatory system is made up of two circulatory systems: the pulmonary that provides oxygen to the blood and the systemic that carries it to all the tissues of the body
Explanation:
The veins transport the deoxygenated blood to the heart pumps this blood back to the lungs, where it absorbs more oxygen. This oxygenated blood returns to the left side of the heart, which pumps it to the rest of the body through the arteries. Pulmonary circulation is a process in which the lungs, heart, veins and pulmonary arteries intervene, with the aim of oxygenate the blood.This system begins in the left ventricle of the heart, since this is the chamber through which it exits deoxygenated blood that has already fulfilled its function in all tissues of the body, to later reach the lungs through the blood vessels in the region.Systemic circulation is a long process that involves the chambers of the heart and blood vessels throughout the body, with the aim of carrying oxygenated blood to the tissues that are further away and thus allow all to function in the best way
Answer:
Because genetic drift (Founder effect) is acting on this population. Not all the Hardy weinberg criteria are accomplished. There are no random matings and populations are finite-sized.
Explanation:
This is a special case of genetic drift: the founder effect.
The “Founder effect” phenomenon refers to cases where a new population originates from a few founder individuals, coming from a bigger ancestral population, that established in a new environment. This small population might or might not be genetically representative of the original one. This subgroup carries with them some genetic information that they share with their original population. Over time, some genes can be lost, or they can increase in frequency. Some rare alleles might be exceeded or might be completely lost. On Consequence, when the small population grows, it will have a genetically different composition from the original one. In these situations, genetic variability is reduced and enhances the possibility of developing a peculiar allelic composition. In some cases, the founder effect is part of the process of speciation.
The criteria for maintaining a Hardy-Weinberg equilibrium are:
- Random matings
- No superposed generations
- No mutations
- No migration
- Infinite population size
- No natural selection
Genetic drift involved the un-accomplishment of random matings and infinite population sizes.
Genetic drift involves:
- limited population sizes
- individuals reproduce by endogamy/exogamy, and matings occur by phenotype.
Answer:
a member of a large group of unicellular microorganisms which have cell walls but lack organelles and an organized nucleus, including some which can cause disease.
Cell walls are unique to plant cells
<span> Gravitational forces are only attractive but electromagnetic forces are both attractive and repulsive.</span> Because magnetic force has negative and positive charges, it can be both attractive and repulsive. Gravity affects objects at a distance, but the attraction weakens as the objects get farther apart.
