Answer:
The two main reasons are nonpolar core of the bilayer and the active transport.
Explanation:
The membrane is structured to have two outer layers that are polar and an inner layer that is nonpolar.
If a membrane protein is exposed to the solvent, i<em>t will also have a polar side. It would be very difficult for the polar face of the membrane to move through the nonpolar core of the bilayer.</em> Therefore, this model is not feasible.
One major form of transport, active transport, moves solutes up the concentration gradient. <em>The binding of a solute and then release on another side of the membrane would only work for facilitated diffusion because it would cause a net movement of solutes down the concentration gradient.</em> It is unclear how energy could be expended to drive this process in the transverse carrier model.<em> Therefore, the transverse carrier model does not explain active transport.</em>
I'm pretty sure it's deposition because the sediments in the water(soil) are building up on the rock.
Mostly any bug you can think of
Asexual reproduction is better because it is more convenient!
1. It only requires one organism
2. Results in more offspring
3. Usually a quicker process
OR
Sexual reproduction is better because it results in more genetic diversity!
1. Requires two organisms of the same species
2. Genetic material mixes together to create a random, unique combination
3. Recombination of genes decreases the chances of defects, diseases and mutations
Hope this helped some! :)
It seems That teh molecules can move towards the membrane
