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.

<span>the plates located at our planet's surface move because of the extreme heat in the earth's core that then leads to the molten rock in the mantle layer to move. it moves in a pattern called a convection cell, it forms when warm material rises, cools down, and eventually sinks down. </span>
Answer:
The correct answer is A malate is stored in the large vacuoles.
Explanation:
During CAM malate is synthesized from oxaloacetate by malate dehydrogenase enzyme.The so formed malate is stored inside large vacuoles during night.
In the day time the guards cells of CAM plants get closed and malate is then discharged.The discharged malate is then transported into the chloroplast where the malate is converted to pyruvate and CO2.
The CO2 then enters into the calvin cycle .
Before a cell divides DNA replicates itself. hope this helps!
