Answer: Facilitated Diffusion.
Explanation:
Most substances use simple diffusion, move across a membrane because they are smaller and polar. But for chloride ions, that is not the case.
Chloride Ions are charged negatively, and since they are negatively charged, they cannon move across the membrane without help from something. Therefore, chloride ions move by facilitated diffusion using carrier proteins.
Facilitated Diffusion is the process of spontaneous passive transport of molecules or ions across a biological membrane via specific transmembrane integral proteins.
That explains how chloride ions can move in and out of cells.

False.
Artries in general have thicker walls than veins. (thicker tunica media)
This is because artries need to withstand high blood pressure when the heart pumps the oxygenated blood to the rest of the body while veins carry blood (deoxygenated) at lower pressures, hence they are thinner compared to artries

The statement 'Exploring the relationship between the material in a rock sample and its hardness' correctly describes an experimental investigation (Option C).
<h3>What is an experimental investigation?</h3>
An experimental investigation is defined as a procedure used in the scientific method to test an explanation or hypothesis, which can be confirmed or rejected.
