The right answer is: controls the movement of substances into and out of cells.
This picture represents a plasma membrane.
The plasma membrane is the membrane that delimits a cell. It separates the cytoplasm from the outside environment.
Special proteins ensure the selective permeability of the membrane (pores), the recognition of chemical signals or carry markers (MHC antigens ...).
The pores are the doors of the membrane. They are macromolecular buildings of protein or glycoprotein nature, sometimes very complex. They are inserted in the bilayer and control exchanges between intracellular and extracellular (with receptors, carriers).
I would go with false, because not only 100,000 genes, there are lots to those. and there are not even like 100,000 genes, that is not really possible!!
hope that this helps you! =)
Answer:
This is an example of a <u>paraphyletic group</u>.
Explanation:
Paraphyletic groups is a group that contains only part of the descendants of a common ancestor. A group is constituted as paraphyletic when one or more holophyletic groups are subtracted from a clade (evolutionary branch). Traditional classifications are loaded with paraphyletic groups, such as invertebrates, pteridophytes, opposites. In each of these cases the group is defined by the exclusion of a smaller group within a larger one. An example is the reptiles are a paraphyletic group, since when we refer to them we are excluding mammals and birds even though they are taxa that evolutionarily descend from reptiles.
