The correct statement regarding the counter current exchange in fish gills are It is a very efficient way to capture oxygen from water, Water flows across the lamellae in the opposite direction of blood flow, Oxygen diffuses into the capillaries across the lamellae, because even as oxygen is depleted, it is still at higher concentration than in the Inflowing blood
Gills are used by fish to exchange gas. Gills have a lot of folds, which increases their surface area. They can extract oxygen at a rate that is three times faster than that of a human because the water flows past their gills in the opposite direction from the blood (this is known as countercurrent flow). Blood always flows close to water that has given up less oxygen due to the fact that it moves in the opposite direction of the water. In this manner, the blood is able to take in more and more oxygen as it flows. Even as the blood, which is about 80% oxygenated, travels to the lamella's conclusion, it passes water, which is at the lamella's beginning and is 90% oxygenated.Even as the blood, which is around 80% oxygen-saturated, approaches the lamella's end, it is passing water, which is 90–100% oxygen-saturated at the lamella's beginning. Because there is still a concentration gradient, the blood can continue to receive oxygen from the water even after it is highly saturated and has passed through most of the lamellae.

Answer:
Explanation:
(1) The defective enzyme, which was suppose to break down drugs, is an oxidoreductase. Since, enzymes that break down drugs or metabolic enzymes perform there functions by oxidizing the drugs.
(2) Both codes are triplet codes for the enzyme; however the normal triplet code ought to be ATT, however there was a point mutation causing the "A" to be "C". These letters represent the bases in the DNA, <u>ATT is adenine-thymine-thymine while CTT is cytosine-thymine-thymine.</u>
(3) Further medications Henry is prescribed could include been taken with a drug/enzyme that will breakdown the actual medication.
6 protons is the amount of electrons so it would be... 6 protons 6 neutrons 6 electrons in all so it is probably 18 protons but im not to sure but..idk good luck
Is there supposed to be a picture for this?
