PassiveCellular Transport (high to low concentration)

▪Diffusion –when, why & how does it occur?
▪Osmosis –when, why & how does it occur?
▪Facilitated diffusion –when, why & how does it occur?

Active Cellular Transport (low to high concentration)

▪Active transport –when, why & how does it occur?

Answer:

1 - Diffusion is when small, non-polar molecules pass through the cell membrane. It happens so that the cell can get vital nutrients, it is a type of passive transport.

2 - Osmosis is the transport of water through the cell membrane. It is a type of passive transport, the water moves to the side of the cell with less water.

3 - Facilitated diffusion is when protein channels or transports help large polar molecules like glucose that ordinarily couldn't get through the cell membrane pass through the membrane.

4 - Active transport is when a molecule requires energy, ATP, to pass through the cell membrane. An example of this is molecular pumps, the use energy, ATP, to work.

5 - Endocytosis is when a vesicle captures an outside substance for the cell. There are two types of endocytosis, phagocytosis, which is "cell eating" where the cell digests solids, the there's pinocytosis, which is "cell drinking" where the cell digests liquids.

6 - Exocytosis is when a vesicle removes a substance from the cell by combining with the cell membrane and pushing it out.

7 - The Membrane is made out of phospholipids

8 - Carrier proteins help molecules that are large and polar get into the cell.

soldi70 [24.7K]

Answer: SPORES are defined as haploid (1n) cells which develops into gametophytes.

Gametophytes inturn produce either haploid (1n) male or females GAMETES that can fuse to form diploid ZYGOTES.

This basically explains what goes on in Meiosis.

ELEN [110]

Answer:

The answer is A.

Explanation:

The example given in the question describes the spontaneous recovery which is a concept that was invented by Ivan Pavlov. It basically states that after the brain is conditioned for a certain situation or stimuli, it takes some time for the habit to adjust in accordance to the change of the situation or stimuli. In this case it is the change of the feeding time. So the answer is A.

I hope this answer helps.
