B) The grass height was the dependent variable.

E) Intermediate numbers of insects had the greatest positive impact on grass growth.

<h3>How insects affect the plant growth?</h3>

The grass height was the dependent variable because it depends on the nitrogenous waste of insects and presence of water. The numbers of insects had the greatest positive impact on grass growth because they provides nutrients to plant in the form of nitrogenous water so we can conclude that option B and E are the correct options.

What is the function of a cell’s selectively permeable plasma membrane?

salantis [7]

<h2>The correct answer is explained below:</h2>

Explanation:

The plasma membrane of a cell is selectively permeable.
This means that the membrane specifically allows only certain molecules to move across it from the interior of the cell to the exterior or from the exterior of the cell to the interior.
The functions of such selective permeability of the membrane are:

It allows only those polar or non polar molecules or ions to traverse them and enter into the cell which are necessary for the cell metabolism or other functions of the cell.
It removes those ions or molecules from the cell interior to the cell exterior which are not necessary for the cells.
It prevents the movement of essential cellular components like non-polar or polar molecules, ions, amino acids, fatty acids, or carbohydrates from the cell interior to the cell exterior.
It prevents the movement of those molecules from the cell exterior to the cell interior which are not essential for the cell functioning.
