Increased aldosterone secretion: High plasma potassium levels, Low plasma sodium levels, Dehydration.
Decreased aldosterone secretion: Low plasma potassium levels, High plasma sodium levels
No change in aldosterone secretion: Balanced plasma sodium and potassium levels
What is aldosterone?A steroid hormone made in the adrenal cortex (the outer layer of the adrenal gland). It helps control the water-salt balance in the kidneys by retaining sodium in the body and releasing potassium from the body. Too much aldosterone can cause high blood pressure and fluid accumulation in body tissues.
High aldosterone levels can cause high blood pressure and low potassium levels. Low potassium levels can cause weakness, tingling, muscle spasms, and temporary paralysis. Your doctor will measure the levels of sodium, potassium, and aldosterone in your blood. Low aldosterone levels lead to low sodium levels (hyponatremia), high potassium levels (hyperkalemia), and a condition in which the body produces too much acid (metabolic acidosis).

Answer: Thrombocytopenia results in disruption in the production of Platelets
Explanation:
Different issues with your platelets include: Thrombocytopenia is the term for decreased platelet counts in the blood. You may be at risk for minor to major bleeding as a result of this. Your immune system may unintentionally target and destroy your platelets as a result of autoimmune illnesses such as immune thrombocytopenia (ITP), lupus, and rheumatoid arthritis. Your bone marrow can be harmed by cancers like leukaemia or lymphoma, which can kill blood stem cells. Your blood clots with the aid of platelets, stopping the bleeding.

the stimulation of auditory nerves depends on the opening and closing of channels in the auditory hair cells. which type of gating mechanism do these cells use?
The cells use a stress-gated gating mechanism as the stimulation of auditory nerves depends on the opening and closing of channels in the auditory hair cells.
The auditory nerve fibers carry the frequency and strength of the sound stimulus to the brain from the internal hair cells. Cochlear tonotopic in mammals is connected to frequency coding. However, phase blocking at the level of hair cells provides the basis for the coding of sounds with a frequency lower than 3 kHz.
There are cation channels that are mechanically gated in the membrane of stereocilia. The tallest neighboring stereocilium's tip is connected to these cation channels by proteins called tip link proteins. These cation channels open as a result of the basilar membrane's vibration, allowing cations—most notably K+—to enter the cytosol of hair cells. The receptor potential depolarizes when cations enter. Thus, the cells use a stress-gated gating mechanism as the stimulation of auditory nerves depends on the opening and closing of channels in the auditory hair cells.
The complete question is:
The stimulation of auditory nerves depends on the opening and closing of channels in the auditory hair cells. Which type of gating mechanism do these cells use?

Why are mutations in body cells not a source of genetic variation?.
This is due to the fact that mutations in body cells have no effect on the DNA of eggs and sperm. While this prevents many harmful mutations from wreaking havoc on offspring, it also reduces diversity and the ability to adapt to changing environments. Sexual reproduction, on the other hand, compensates for this loss, at least in part.

A student has two flasks of growing algae. to one flask he adds some phosphorus, while he leaves the other flask alone. At the end of the day both populations are stable, but the phosphorus-containing flask has 10 times more algae as the phosphorus increased the carrying capacity of the environment.
Too much phosphorus can promote the growth of algae and large aquatic plants, resulting in lower levels of dissolved oxygen- a process known as eutrophication. High phosphorus levels can also cause algae blooms, which can produce algal toxins that are harmful to human and animal health.
Phosphorus (P) is a necessary element for plant and animal growth, as well as for profitable crop and livestock production. It can also boost surface water biological productivity by hastening eutrophication, the natural aging of lakes and streams caused by nutrient enrichment.
Phosphorus, like nitrogen, is an essential nutrient for all life.

Evolution is a term that describes how an organism evolved from another form that is different from its current form.Of the options given, random mating is not an evolutionary mechanism.
Take people for example. Humans were thought to have evolved into humans (through several evolutionary steps) from Australopithecus.
There are several mechanisms that contribute to evolution. Mutation, non-random mating, gene flow, finite population size (genetic drift), natural selection, etc.
Mutations are the original cause of all genetic variation, but mutation rates in most organisms are rather low. Therefore, the impact of novel mutations on allele frequencies from one generation to the next is usually not large.
Non-random mating. In non-random mating, organisms may prefer to mate with other organisms of the same genotype or different genotypes.
Gene flow involves the transfer of genes to and from populations by either individual organisms or their gametes (egg and sperm, e.g. by pollen dispersal through plants).
Population size is not infinite (genetic drift). Genetic drift includes changes in allele frequencies due to random events. This is literally a "sampling error" when selecting next-generation alleles. Drift can occur in populations of any non-infinite size, but affects small populations. natural choice. Finally the most famous evolutionary mechanism! Natural selection occurs when alleles (or combinations of alleles from different genes) make an organism more or less compatible, that is, allow it to survive and reproduce in a particular environment.
