The force required to prevent the movement of water across a selectively permeable membrane is __________ pressure

Biology
1 answer:
SOVA2 [1]2 years ago
5 0

The force required to prevent the movement of water across a selectively permeable membrane is osmotic pressure. The plasma membrane forms a vesicle around the substances to be transported, and the vesicle around the vesicle is taken into cells.

Osmotic pressure depends on both the pressure gradient and concentration gradient.  This is only affected by the temperature and concentration of solute, each affect the movement of water across a membrane.

Higher the concentration is higher temperature increases osmotic pressure, which produced or associate with osmosis and dependent on molar concentration and absolute temperature. Hydro-static pressure forces fluid out of the capillary , osmotic pressure draws fluid back in.

explain how a carrier protein can facilitate the diffusion of glucose or other substances into the cell.
Sveta_85 [38]

Specific chemicals are bound by carrier proteins and transferred on one side of the membrane. The conformational changes they go through next enable the molecule to cross the membrane and exit on the other side.

How carrier protein facilitate the diffusion?

When a molecule diffuses, it usually moves from a high concentration location to a low concentration area until the concentration is the same everywhere in the space.

Contrary to channel proteins, another form of membrane transport protein that is less selective in the molecules it transports, carriers are proteins that move a particular material through intracellular compartments, into the extracellular fluid, or across cells. Carrier proteins are found in lipid bilayer cell structures such cell membranes, mitochondria, and chloroplasts, just like other membrane transport proteins.

Therefore, carrier proteins can facilitate the diffusion of glucose or other substances into the cell.

nikdorinn [45]

Answer:

c. A chromosomal mutation can change the total number of chromosomes in the cell.

Explanation:

A gene mutation affects a single gene, and replication error is the main cause of gene mutation. A chromosomal mutation affects one part of chromosome or full chromosome. error in meiosis is the main cause of chromosomal mutation. Both mutations are responsible for a change in DNA. A chromosomal mutation leads to the change in total number of chromosomes in the cell.
