Answer:

The Continental drift theory

Explanation:

The Marsupials are the mammals that are mostly found in Australia and America and are characterized by the presence of a pouch that is attached to their body.

These mammals evolved from the reptiles and present abundantly in the Cenozoic era, after the extinction of dinosaurs. But they first appeared during the time of existence of dinosaurs. The continents of Australia and America eventually got separated before the naturally occurring placental mammals could evolve. This suggested a piece of evidence for the continental drift theory.

This theory describes that the continents float across the large oceans from one place to another with respect to the fixed poles.

Organic molecules derived from vitamins that act as helpers are called
AysviL [449]
Coenzymes

Coenzymes are small organic molecules that, themselves, do not function as catalysts (i.e. enzymes) but aid the latter in carrying out their functions. Enzymes are biological catalysts, which means that they allow reactions to occur at lower activation energies. In a way, enzymes help to "speed up" chemical reactions. 

Coenzymes are mostly derived from vitamins. Examples include TPP from Vitamin B1 (thiamine), FAD from Vitamin B2 (Riboflavin), and NAD+ from Niacin.

Which individual are favored in natural selection?
Airida [17]

Hello! :)

It would take forever listing all the animals that have adaptations that helps them survive in their environment.

Natural selection is the process by which individuals with characteristics that are advantageous for reproduction in a specific environment leave more offspring in the next generation, thereby increasing the proportion of their genes in the population gene pool over time.

Hope this helped and I hope I answered in time!

Good luck!
