Answer:

Nucleotide bases.

Explanation:

Unique sequences of bases makes up a nucleotide. These nucleotide sequencing are used by DNA as a genetic code of information that determines type of cells, proteins and the whole organismal structure.

There are four nucleotide bases, Adenine and guanine termed purines are big, cytosine and thymine called pyrimidines are small. A purine pairs with a pyrimidine, such that adenine pairs with thymine and guanine pairs with cytosine. The bases are the same but each DNA uniqueness lies in the sequence of base pairing.

Ann [662]

Answer: C. Radical global climate change.

Explanation:

The entire taxa of the species can be wiped out due to an large catastrophic event associated with the change in the climate. As the climate becomes warm the chances of undergoing the global precipitation rate will change. The climate being an important abiotic factor under unstability is likely to affect the amount of rainfall, snow fall, drought and conditions of desertification. All these factors can be responsible for the removal of the entire taxa of the species in short time.

(c) Mechanical gated

Explanation:

Mechanical gated channels are controlled by mechanical forces applied to the channel, this happens when a distortion of the cell membrane causes a deformation on the membrane channels and thus they change their conformation in order to star or stop the exchange of some molecules.
