What happens to the effenciency of the exchange of oxygen in the human body at a high altitude​

Biology
1 answer:
Daniel [21]3 years ago
7 0

Answer:

The effiency decreases at higher altitudes

Explanation:

The higher up a person is on a mountain, the thinner the air is due to the lack of plants that can grow. An example of this is Mount Everest. At a certian point on the mountain, called the "Death Zone", the air is too thin to supply enough oxygen to the human body to survive. That's why they bring oxygen tanks with them on their adventures.

Why might it be beneficial for the brain to be connected to the contralateral side of the body?
kondor19780726 [428]
I think it is beneficial for the brain to be connected to the contralateral side of the body because of the position and connection to the brain that our eyes have. Because light from the right visual fields strikes the left side of the eye and light from the left side strikes the right side of the eye, the connections allow visual information from both sides of the body to reach the brain.

You are examining the phylogenic relationship of a newly discovered plant species (Species 2). You amplify the RUBISCO barcode a
frozen [14]

Answer:

a. Inversion

b. Duplication

Explanation:

Inversion has the name suggest, has to do with a segment of DNA being reversed from end to end.

In this case here,

Inversion is taking place here.

species 1 ATGCAAATTTGGGCCCATGAATGGTTGCAA

species 2 ATGCAAAAATTTTGGTACGCCGAATGGTTGCAA

Therefore, the sequences in bold in species 1 are observed to be reversed end to end in species 2.

Deletion ❌❌

I am sure it's not feasible because deletion entails removal of a few sequences.

It can be seen that species 2 is longer than species 1, which gives another reason why deletion is not feasible too, as no sequences are seen to be deleted.

I believe duplication is feasible since AATT sequences are repeated once.

Our final answer,

inversion and duplication occur here.

Why do some regions specialize in "milk products" like cheese and butter rather than fluid milk? identify some of these importan
kati45 [8]
This happens because these regions are located further away from urban areas and the milk can easily get spoiled before it is delivered to the consumers. Therefore, dairy farms which are away from urban areas, process the milk in order to produce milk products that can last longer. Milk products such as butter or cheese can stay fresh for a longer period of time and they do not get spoiled before reaching the consumers. New Zealand is a place where this practice is quite common since it is located at a great distance from important markets, such as Europe and North America. Milk can be shipped at such a great distance only in the form of processed milk products.
