Which best describes the difference between osmosis and diffusion

Answers

Osmosis is the specific movement of solvent molecules through a semi-permeable membrane, while diffusion is the general movement of particles from high to low concentration in any medium.

Osmosis and diffusion are both fundamental processes of passive transport. Osmosis is a subset of diffusion that specifically involves the movement of solvent molecules, usually water, through a semi-permeable membrane to equalize solute concentrations on both sides of the membrane. It's essential in processes like maintaining cell turgidity.

On the other hand, diffusion encompasses the broader concept of particles, including solutes and gases, spreading out from areas of high concentration to low concentration. It occurs in various environments, not limited to membranes, and is vital for processes like gas exchange in respiration and the distribution of nutrients in cells.

. Limb bones within unrelated animals that have the same basic structures are considereda. vestigial structures.
b. homologous structures.
c. embryological.
d. analogous structures.

Answers

When you have unrelated animals in biology which have limbs that have the same basic structure we consider these things to be homologus. As the first poster noted, an example is a wing of a bird or a hand of a human. When we're talking about analogous structures, we're talking about things which perform the same function yet don't have the same structure.
