In a clade, mammalian has the three descendents: monotreme, marsupials, and eutheria. what will these three descendents together be called?

The correct answer will be- sister group or crown group.

Explanation:

A clade is the group of the organism which has descended from a common ancestor.  The visual representation of clade is known as a cladogram which shows the relationship between organism in tree-form.

In the visual representation, when two branches appear growing from a common branch, the two branches will be called "sister groups or crown groups".

Since three mammalian namely monotreme, marsupials, and Eutheria are thought to have descended from a common ancestor of mammals, therefore, they will be called "sister groups".

Thus, the sister group or crown group is the correct answer.

option c is the correct answer.

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.
