5 0

Answer: Option D

Explanation:

The Continental drift can be defined as the theory that states that the sub continents that are seen today were once a large content.

The continents separated into small parts over a period of time and are known as sub continents today.

How do large molecules move across the cell membrane through facilitated diffusion?
Svetlanka [38]

Answer:

Explanation:

In facilitated diffusion, molecules diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers. A concentration gradient exists for these molecules, so they have the potential to diffuse into (or out of) the cell by moving down it.

We can test the relative permeability of a phospholipid bilayer by using a synthetic membrane that does not contain any protein
Deffense [45]

Answer:

Glucose.

Explanation:

The cell membrane is made up of lipid bilayer and proteins are embedded or may span the lipid bilayer. The carbohydrates are present in association with lipids and proteins.

The artificial membrane has been prepared that are free from proteins. Small uncharged particles may easily diffuse through the membrane. Among the given molecules in the question water is the smallest molecule and diffuse out first through the plasma membrane. Ethanol is 2 carbon compound and diffuse after water than glycerol diffuses as it is a 3 carbon compound. Glucose is the largest molecule and diffuse last through the plasma membrane.

Thus, the correct answer is option (A).
