The term ""biomagnification"" means that a chemical ____ at each trophic level in a food chain or web.
Tasya [4]

Answer:

Increases

Explanation:

Biomagnification refers to a phenomenon in which the harmful toxic chemical gest magnified or amplified or increases in the food chain trophic level.

The biomagnification is caused by the bio-accumulation of the toxic material in the organisms.

The harmful toxic chemical enters the food chain through eating like when the crops are sprayed with pesticides and insecticides runoff in the water. From there the toxic material enters the aquatic food chain like from the planktons to fish and then to vultures.

The organisms at higher trophic level die because of the accumulation of the infected lower trophic organisms.

Thus, Increases is the correct answer.

Which statement is NOT part of the Mitchell chemiosmotic hypothesis? High‑energy phosphorylated intermediates that serve as phos
gogolik [260]

Answer:

High-energy phosphorylated intermediates that serve as phosphate donors to ADP are generated as a result of electron-transfer reactions.

Explanation:

Peter Mitchell proposed Chemiosmotic hypothesis which state that the driving of the synthesis of ATP is accomplished by a proton-motive force. He propose that whenever electron is moved along the electron transfer chain then proton will be moved accross the inner part of mitochondria membrane. As a result of this there would be increase in PH of the mitochondria matrix and reduced PH of the intermembrane space.

Some Evidence about Chemiosmotic hypothesis hypothesis;

1)transportation of electron brings about the generatation of a proton gradient. there is difference in the PH on the outside and inside the mitochondria.

2)To synthesis ATP, a proton gradient is required only and other means by which PH gradient is generated

Therefore,High-energy phosphorylated intermediates that serve as phosphate donors to ADP are generated as a result of electron-transfer reactions is not Micheal Mitchell statement.
