Answer:

this phenomenon is a natural consequence of evolutionary processes and continental drift  

Explanation:

Marsupials are mammals in which newborn offspring are carried in a pouch of the female (mother) body. On the other hand, placentals are mammals that complete embryo development in the mother's body, in the placenta. All the extant marsupials are endemic to Australia and the Americas. It has been shown that marsupials diverged (evolved) in South America, Australia and Antarctica when these landmasses were joined. In Australia, marsupials evolved to fit an ecological niche, which can be attributed to geographic isolation due to continental drift, while placental mammals are relatively recent and more scarce (mainly bats and rodents) within this region.

Explanation:

The correct statement regarding the structure in the above image is as follows: negatively charged regions of molecules tend to have carboxyl groups (option A).

Amino acids are the monomeric components of proteins. They are any organic compound containing both an amino and a carboxylic acid functional group.

The amino group has a formula -NH₂ while the carboxyl group has a formula -COOH.

According to this question, the ability of the carboxyl and amino groups to adopt a charge in biology makes them very important functional groups in proteins.

As observed in the image of the amino acids, only the carboxyl group carries a negative charge (-), hence, it is correct that negatively charged regions of molecules tend to have carboxyl groups.
