Constants never change.

Controls typically don't change or they are done by standard means

(like in an experiment where you water plants with sodas, the plant you use water with is the control)

Dependent variables are the outcome of the experiment. This is the result of changing something.

Independent variables are what you are testing. A independent variable is something that is  intentionally altered.

easy way to remember it is that dependent variables depend on what other variables are. so you cant change a dependent variable, but you can change the other variables.

A cell membrane that transports glucose, ions, or other charged or polar molecules is likely to have a higher percentage and gre
erica [24]

Answer: True

Explanation:

<u>A cell membrane consists of a lipid bilayer made of polar phosphate head and a nonpolar lipid tail.</u> It is semipermeable and regulates the transport of materials through it. For this,<u> it is selectively permeable</u> and since it is made of lipids, hydrophobic and small polar molecules can diffuse easily through it by simple diffusion and down their concentration gradient. However, polar molecules, large molecules (such as glucose) and ions are not able to pass through it because they are repelled.

To accomplish the transport of these molecules that can not diffuse, proteins embebbed in the membrane function as carriers that enable the transport of polar molecules, large molecules and ions by passive (through facilitated diffusion, down its concentration gradient) or active transport (movement against its concentration gradient).
