Biomolecules include large macromolecules (or polyanions) such as proteins, carbohydrates, lipids, and nucleic acids, as well as small molecules such as primary metabolites, secondary metabolites, and natural products. A more general name for this class of material is biological materials.
Answer:
The correct answer is - false.
Explanation:
Penicillin-binding protein 2a or PBPs are protein produced by bacteria that binds with the β-lactam antibiotics such as penicillin. They play role in the cell wall synthesis of bacteria by producing peptidoglycan by catalyzing the reaction.
β-Lactam antibiotics bind with the PBPs and cause the disruption to peptidoglycan cross-linking in the biosynthesis of the cell wall and ultimately lysis of bacteria takes place and cell death.
Answer:
<em>Some enzymes help break large molecules into smaller pieces that are more easily absorbed by the body. Other enzymes help bind two molecules together to produce a new molecule. Enzymes are highly selective catalysts, meaning that each enzyme only speeds up a specific reaction.</em>
Answer:
Biomimicry is important for animals for survival, as looking like a known dangerous animal can lower its chances for being attacked. An example is the monarch butterfly, and its mimicked viceroy butterfly, having nearly identical wings.
Explanation:
Answer:
At each higher level of consumption, the amount of toxin is magnified.
Explanation:
Those predators all eat smaller secondary consumers, and those secondary consumers eat the primary consumers, which a lot of the times are exposed to DDT. For example bugs are often the primary target for DDT, once those bugs are exposed to the DDT they carry it in/with them. When a fish eats the bug, that fish is now exposed to the DDT. When the fish is caught and eaten by an eagle that eagle and its young are now being exposed to DDT. The DDT might not effect the full grown eagle for its lifetime but it does effect its young.
