We can confirm that one classification often used to describe the gas exchange that occurs in the alveoli-capillary membrane is external respiration.
<h3>What is external respiration?</h3>
This is a term used to describe the gas exchange that occurs in the alveoli-capillary membrane, where oxygen is received and carbon dioxide is released from the body. On the other hand, internal respiration is when the oxygen reaches the organs and tissues and another exchange of gasses takes place.
Therefore, we can confirm that one classification often used to describe the gas exchange that occurs in the alveoli-capillary membrane is external respiration.

There are four bases found in DNA: adenine (A), cytosine (C), guanine (G), and thymine (T). Adenine forms a base pair with thymine, and cytosine forms a base pair with guanine. There is a one-to-one relationship in these base pairings (Chargaff’s rule), which means that if you know the percentage of any one of them within a given DNA sample, you can calculate the percentages of the other three. In this case, you're given the percentage of guanine, and you want to find out the percentage of adenine.
Since guanine base-pairs with cytosine and since there must be as much cytosine as there is guanine, 41% of the bases in this gene are cytosine as well. That means that adenine and thymine <em>together </em>make up the remaining 18% (100% − 41% G − 41% C) of the base pairs. If there must be an equivalence in the number of thymine and adenine bases per Chargaff's rule, then half of the remaining base pairs must comprise adenine and the other half comprise thymine. Half of 18% is 9%.
Thus, adenine makes up 9% of the bases in this gene.

What system of your body would be activated if you were surprised?
Endocrine system would be the system of your body that would be activated if you were surprised. Your endocrine system creates and liberates hormones that sway other body parts or glands, even your emotions.

Answer:
grinding
Explanation:
The streams are very powerful agents when it comes to erosion. With their power and chemical composition, the streams manage to erode the rocks easily and even the hardest rocks experience significant changes or are totally destroyed over time. The water of the streams manages to break down the rocks into small or big pieces, and as it does it moves them away. The rocks that are carried are constantly colliding with other rocks along the way, causing even more pieces to break and to be eroded, thus the grinding type of stream erosion.
