Answer:
D -- ATP synthesis when the phosphate donor is a substrate with high phosphoryl transfer potential
Explanation:
Substrate- level phosphorylation is the synthesis of ATP from ADP by the transfer of phosphoryl group from a substrate with high phosphoryl group potential to the ADP molecule.
In substrate-level phosphorylation, the donor is a phosphorylated intermediate molecule with a high phosphate transfer potential and it is a way through which phosphate in introduced into a molecule, the other two ways are oxidative phosphorylation and photophosphorylation. In substrate-level phosphorylation, a PO4^2- is transferred from a phosphate intermediate (substrate) to ADP to form ATP. Phosphorylase and kinases are enzymes involved in this reaction. An example is the reaction in glycolysis which involves phosphoenolpyruvate and ADP to form Pyruvate and ATP. This is to ensure adequate supply of energy to cells and also during anoxia so as not to make mitochodria strain the glycolytic ATP reserves.
Cyclobenzaprine is a drug that produce an anticholinergic response in the body, which means that is blocks neurotransmitters from the nervous system to prevent things like muscle spasms. but due to the neurotransmitters being blocked, it can cause these kinds of side effects because the brain can no longer control these things.

Operons afford the organism the opportunity to
simultaneously regulate transcription of multiple genes, whose products are
active in the same process. Operons lead to the synthesis of groups of functionally
related enzymes, usually from a single mRNA transcript hence makes regulation of
the genes highly efficient.
Answer:
a. Biomagnification
Explanation:
Biomagnification is the name given to the progressive accumulation of substances from one trophic level to another along a food chain. Thus, the substance will have its highest concentration in individuals who occupy trophic levels furthest from producers.
For biomagnification to occur, substances must be fat soluble (lipid soluble) and thus adhere to living tissues. Another feature of substances that undergo biomagnification is that they are generally not biodegradable or metabolized by the body.
The phenomenon is quite common with heavy metals (lead; mercury) and certain chlorinated and aromatic organic compounds with higher molecular mass, such as the insecticide DDT.
