A--When someone hike, how will the altitude affect your body?
Gelneren [198K]

Answer:

The maintenance of the body's physiology is important for the living organisms.The metabolism of the human body affects with the temperature, altitude and with the other external and internal conditions of the body.

In case of higher altitudes, the partial pressure of the oxygen is low. This causes the increase in the breathing rates so the oxygen amount in the body can be increased. The dehydration of the body may also occur for the few hours as the individual reaches the altitude. The body's metabolism also increased with the increase in the altitude.

Each of the species of finches on the galapagos islands has its own distinctive ________ and ________.
sergiy2304 [10]

Each of the species of finches on the Galapagos Islands has its own distinctive beak and ecological niche.

<h2>Reason :</h2>

Darwin observed that the finches evolved thanks to the difference in their habitat. Consistent environmental differences in several habitats on different islands in the Galapagos, the supply of different foods sources (seeds, cactus, insects, and fruit) promotes directional selection on resident finches for optimal beak morphology which maximizes survival under local conditions.

This process has produced more distinct species of finches, all unique to the archipelago. He noticed that every finch species is having a different type of beak, counting on the food available on its island.

3. In most cells,
dmitriy555 [2]

Answer:

In most cells, DNA directs the production of a molecule of mRNA which then enters a ribosome. The ribosome produces the final product, a protein. Retroviruses do the opposite. They use the enzyme reverse transcriptase to use a template of mRNA to produce DNA.

Explanation:

The central dogma of molecular biology describes how a cell uses its genetic information to synthesize a protein. The first step called 'transcription' consists of using an RNA polymerase enzyme and a fragment of DNA (i.e., gene) as a template to synthesize an RNA molecule, usually a messenger RNA (mRNA). Subsequently, the genetic code in the mRNA sequence is read by the ribosomes in order to produce a protein, a process known as 'translation'. Retroviruses are viruses that have the ability to integrate into the host genome by using a reverse transcriptase enzyme that allows reverse transcription of mRNA to complementary DNA, which then integrates into the host's genome.
