The smallest and most exclusive grouping category is species.
This evidence suggest that all three living creatures that are mentioned have a common ancestor, even though they have been split into different types of groups of living organism millions of years ago.
Science suggests that all of the living organisms on the planet have a common ancestor. Since we are talking about a common ancestor that lived few hundred million years ago, the living organisms split into different groups, and they do not resemble each other nowadays. The fruit fly is an insect, and the humans and mice are mammals, so they are into totally different groups, and it is easy to see by the genetic evidence that they are very distantly related, but the humans and mice are much more closely related because they belong to the same super family, and their connection is much more recent.
Answer:
<h2>
Cockroaches are generalized insects with few special adaptations, and may be among the most primitive living Neopteran insects. They have a relatively small head and a broad, flattened body, and most species are reddish-brown to dark brown. They have large compound eyes, two ocelli, and long, flexible antennae.</h2>
three pairs
Thorax. On the thorax, all cockroaches have three pairs of legs. Adults of most of the domestic species have two pairs of wings, although one species, the oriental cockroach, has poorly- developed wings in both sexes.
Answer:
C. Guard cells and storage parenchyma cells each make a different set of proteins, which determines each cell type's structure and function.
Explanation
Both of these are two types of specialized cells that make specific combinations of proteins, which allows them to have unique structures and functions.
Well, we are all made differently because we have different DNA.
