A point mutation or substitution is a genetic mutation where a single nucleotide base is changed, inserted or deleted from a sequence of DNA or RNA. Point mutations have a variety of effects on the downstream protein product—consequences that are moderately predictable based upon the specifics of the mutation.

Believe it or not, 99.9% of the species on Earth have gone extinct. Now, not all of these were caused by Humans, some were caused by MAJOR cataclysmic events such as the extinction of dinosaurs or other prehistoric animals that make up a large amount of the species on Earth. And remember that all the prehistoric plants are also included, because every plant organism is ALSO a species.

Sure. Single-cell organisms include bacteria and hens' eggs.
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.
