Answer:
A. C4H8C4 - NOT
B. C12H12C4 - NOT
C. CóH1206 - yes
D. C4H2020 - NOT
Explanation:
Carbohydrates are one of macro molecules made up of carbon, hydrogen and oxygen. These are essential molecule as they provide nutrition and makes structural component in plants too.
The ration of carbon, hydrogen and oxygen is similar in almost every sugar or carbohydrate which is 1:2:1, one carbon molecule and one oxygen molecule per two molecule of hydrogen.
In choice A, and B have no oxygen molecule so they can not be carbohydrate, where as D have inappropriate ration in comparison to the carbohydrates.
Thus, the correct answer is :
A. C4H8C4 - NOT
B. C12H12C4 - NOT
C. CóH1206 - yes
D. C4H2020 - NOT
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.

False. Tropical rain forests and coral reefs each have many different species living among them. Therefore, They would have a high biodiversity. Hope this helps!
A hypothesis is when you make an educated guess before you complete the experiment. It is basically an inference on what might happen next. So a conclusion made based on facts.
