A group of students wants to study the structures of animals in the desert. One question they should ask is-
Brrunno [24]

From studies and research, I believe the proper question would be:

"How do the animals satisfy their need for water?" or "How long do the animals live?"

Explanation 1:

When studying the desert, asking "Can you buy the animals in pet stores?" is not going to help you find information about the desert because it is not a question to get information about the desert, only information if you just buy it at your local pet shop.

Explanation 2:

Asking "How many offspring do the animals have?" does help us learn about animals, but we are trying to find information on the structure of the desert in which the animals live in. We are not looking for how many children the animals will have because it doesn't fully relate to the question we would be asking.

Side Note: Offsprings mean children.

Rotenone, a toxic compound isolated from plants, strongly inhibits the transfer of electrons from iron-sulfur centers in Complex
Darya [45]

Answer:

(A) It prevents electron flow from the iron-sulfur centers in complex 1 to the ubiquinone. Due to reduction in electron transfer rate, there is a decrease in the production of ATP which is dangerous for some insects and fish over time.

(B) It also prevents electron flow from cytochrome b to cytochrome c1 at the complex III which leads to QH2 accumulation. If oxidized Q is not present, these is alteration of electron flow and the production of ATP is altered.

(C) Rotenone only prevent electron transfer into the chain at Complex 1  but it does not affect electron transfer at Complex II. Although there is slow ETC, it does not stop completely. However, Antimycin A prevents the oxidation of QH2, the final electron acceptor crom complex I and complex II. Thereby, stopping the production of both ETC and ATP. It can be concluded that antimycin A is a more potent poison.

Explanation:

Rotenone prevents electron flow from the iron-sulfur centers in complex 1 to the ubiquinone. Due to a reduction in electron transfer rate, there is a decrease in the production of ATP which is dangerous for some insects and fish over time. Antimycin A also prevents electron flow from cytochrome b to cytochrome c1 at the complex III which leads to QH2 accumulation. If oxidized Q is not present, there is an alteration of electron flow and the production of ATP is altered. Antimycin A is more potent than rotenone.
