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.

Rattlesnake venom contains a collection of different enzymes, from phospholipases (which hydrolyze phospholipids into fatty acid
zhenek [66]

Answer:

Lipid bilayer

Explanation:

Red blood cell is surrounded by a cell membrane that separates its interior from the surrounding medium. The cell membrane is a lipid bilayer and consists of two layers of phospholipids. The polar heads of phospholipids make the surfaces of the cell membrane while their nonpolar tails are buried in its core.

The snake venom has phospholipase enzymes that digest the phospholipids into fatty acids. Digestion of phospholipids of the lipid bilayer of red blood cells would cause leakage of their content into the surroundings and loss of integrity of cells.
