Fats and lipids are hydrophobic which makes them water repelling compounds. Therefore, presence of a waxy coating on the outer skin of the desert plant prevents loss of water via evaporation from the skin of the plants. This helps the plant store water and increases its survival period.
The process should be called biomagnification.
Biomagnification occurs because if one animal has some toxic substances in its body like pesticide, a larger animal that that has a higher trophic level than the smaller one will consume the smaller animal, and that the toxic substance is consumed too. However, the larger animal does not only consume one smaller animal, but a lot more. Therefore, if all the smaller animals have the toxic substance, the level of the toxic substance magnifies in the larger animal.
This cycle continues by a even larger animal eats more of the large animal and so the toxic level is even further magnified for the even larger animal. This goes on and on until the toxic level has reached a level that can kill the animal.
Biomagnification is often mixed up with bioaccumulation. Bioaccumulation happens in one organism, instead of the whole food chain. Bioaccumulation is where the toxic substance accumulates in only the organism. Since the substance cannot be excreted away. But bioaccumulation does not involve the higher trophic levels.
Therefore, your answer should be biomagnification.
Answer:
The answer is letter C.
Explanation:
The spliceosome can not excise RNA sequences bounded by an upstream 5' splice site and a downstream 3' splice site.B
Because it is not possible to produce an mRNA with the composition Exon 1 Intron AExon 3, it would require the use of two 3' splice sites.
