Looking at the food chain & relationships between organisms can give you a good idea of theoretical cause and effects.
For example:
Starfish are the natural predators of the mussel. If the starfish, that eat the mussels, were to be taken out of the picture: there would most likely be a higher population of mussels.
Hydrogen Cyanide is an example of a blood agent.
Answer:

Explanation:
The given compound is an alkane because all the bonds between carbon are single. Alkanes have all single bonds and are thus called saturated hydrocarbons.

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.
AN-PEP enzyme refers to a dietary supplement, which has been shown to dissociate gluten in the stomach. It has been proven to help the individuals suffering from Gluten sensitivity or Celiac disease. The scientific name of the enzyme is Aspergillus Niger prolyl endoprotease.
However, certain structural differences would take place between AN-PEP, which prevent the enzyme from digesting the peptides. Some of the differences like amino acid differences would be expected in the active site, and in the regions, which influence the folded composition of the active site.
