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.
Answer:
May be of the environment they live or genetics.
Explanation:
This naked mole rat species evolved back to an ectothermic life style rather than staying endothermic like all other mammals because of the environment they live or change in the genetic makeup. The main reason for this evolution may be the environmental they lives or through the change in genetic makeup of this naked mole rat species so both factors can contribute in the evolution.
<span>A single stranded nucleic acid that plays a role in protein synthesis is known as the messenger RNA or mRNA (messenger Ribonucleic Acid). The other two types of nuclei acids are transfer RNA or tRNA and ribosomal rNA or rRNA. These nucleic acids are involved in cellular division in cells, during which transcription and translation occurs.</span>
