Answer:

The correct answer to the question: Regarding plasma membranes, which of the following statements is false, would be, B: The thickness of the plasma membrane is only about 1 nm.

Explanation:

The plasma membrane is the structure of the cell that provides a protective barrier, between a cell´s intracellular environment and the extracellular matrix. Furthermore, aside from providing structural support, and protection, a cell´s membrane also serves as a communication media between the cells, and between a cell and all other elements outside of it. This membrance is formed by a phospholipid bilayer, with a space in between the two layers where the tail ends meet and it also has in its structure cholesterol and other lipids that allow the membrane to be fluid, but also structurally strong. However, what is not true is the thickness, as it is known that plasma membranes´ thickness actually lies between 7.5 to 10 nm, and not merely 1 nm. This is why the answer is B.

andrew11 [14]

Answer:

E. climax

Explanation:

Even though it is not something that is very common in nature, there are still certain exceptions where certain communities manage to reach a point of equilibrium.  This basically is a community of small number of dominant prominent species that create a stable ecosystem. This state of equilibrium is known as climax community. This type of community appears when the web of biotic interactions between the organisms becomes so intricate that there is no possibility of other species to be admitted in it.
