In humans, what is the results when a valve is leaking blood backward in the heart

Biology
1 answer:
Sav [38]3 years ago
3 0

This causes a phenomenon referred to as valve regurgitation. This reduces the flow of blood in the blood vessels and causes a reduction in the oxygenation of tissues of the body. This causes homeostatic signaling by the body resulting in the exertion of the heart pumping and increased breathing (heavy breathing). This is why some of the symptoms include shortness of breath,   fatigue, and light-headedness.

What was the Court’s decision in United States v. Nixon (1974) and how did the decision uphold the idea that even the President
vladimir1956 [14]

Answer:

The Supreme Court decided that the President was required to turn over tape recordings and other materials that had been subpoenaed by special prosecutor Leon Jaworski.

In trying to withhold some materials related to the Watergate investigation, Nixon's lawyer had argued that the President of the United States "is not subject to the processes of any court in the land except the court of impeachment." The Supreme Court disagreed, in unanimous fashion. They held that the President could not use executive privilege as an excuse for hiding wrongdoing or avoiding prosecution. In an interview some years after his resignation, Nixon still held to his view, claiming that when the President does something, "that means that it is not illegal." He felt that being in the position of President put him above the law. But the Supreme Court had firmly disagreed. They rejected the idea of "absolute, unqualified Presidential privilege of immunity from judicial process under all circumstances." Executive privilege can only protect matters of military or diplomatic confidentiality

What does it mean to say that an allele is "fixed" in the population?
Gemiola [76]
Alleles are the individual genes that give rise to certain characteristics in an organism.

When an allele is "fixed" to a population, this means that the characteristic will be constant & most likely will not change until the environment changes as well.

Like with arctic hare, the alleles that influence the color of their coats (white in the winter & brown in the spring/summer) will stay because any fur pattern other than the aforementioned characteristics with result in becoming someone else's food with the lack of camouflage.

Hope that helps!
