Answer:
The correct answer is: C) Membrane lipids diffuse within the plane of the membrane.
Explanation:
Membranes are mostly made from phospholipids that, in aqueous environments, are arranged forming two layers (the hydrophilic heads are in contact to both the intercellular and extracellular spaces, and the hydrophobic tails make contact to one another in amidst the layers). These lipids that make up the bilayer diffuse laterally within the plane of the membrane and thus constitute the <em>fluid mosaic model</em> of cell membranes.
RIbosomes
The rough endoplasmic reticulum is where most protein synthesis occurs in the cell. The function of the smooth endoplasmic reticulum is to synthesize lipids in the cell. The smooth ER also helps in the detoxification of harmful substances in the cell. Ribosomes- Organelles that help in the synthesis of proteins.
cell membrane
A selectively permeable membrane allows some molecules across but not others. The cell membrane controls what enters and exits the cell and thus protects the cell.
Evaporation occurs when matter is changing from a liquid to a gas.
Answer:
A physical change involves a change in physical properties. Examples of physical properties include melting, transition to a gas, change of strength, change of durability, changes to crystal form, textural change, shape, size, color, volume and density.
