The puzzle shapes also helped them understand his theory, so did tectonic plates, I gave you all I know! I wish I could help more but I haven’t learned this stuff in years! I’m sorry! Anyways hope you find out!
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.

in an ecosystem, fungi play the role of decomposers -- they break down dead organic matter and return vital nutrients to the soil. Without fungi, nutrients would not cycle through an ecosystem, causing the breakdown of the entire food chain.
hope this helps :)
The beaks are different depending on the food available on the island.
Answer:
Explanation:
The rate limiting reaction of aerobic respiration involves the phosphorylation of fructose phosphate by the enzyme phosphofructokinase. The rate at which this enzyme makes product is [increased, decreased] when ATP levels rise because the molecule ATP binds to an allosteric site on the enzyme and acts as a direct inhibitor. When ATP levels fall AMP binds to the allosteric site of phosphofructokinase. This interaction leads to an increase of cellular ATP, so that this is an example of a negative feedback loop.
