Answer:

\boxed {\tt B. \ They \ move \ through \ tiny \ pores}

Explanation:

Cell membranes are selectively permeable, which means certain molecules can pass in and out, but others cannot.

One factor is size. Small molecules can move through openings in the membrane, but bigger ones cannot pass and usually need assistance from carrier proteins.

Therefore, the best answer choice is B. They move through tiny pores

¿Cuál es la importancia de la fusión nuclear? What is the importance of nuclear fusion?
Rama09 [41]

Without it, there are no stars, including our own sun, and there wouldn’t be us talking about it.

It is used in particularly destructive bombs.

At a tiny scale, it can be used to produce neutrons, eg, a Farnsworth Fusor.

At a large scale, we have yet to figure out how to make controlled fusion work in a way that runs for a long time and generates collectible power we can use to feed the process. This has remained elusively 20 years out from the current state of affairs for 50 years.

If it was made to work, then it would probably be a good source of clean energy that would be safer than many of the non-renewable alternatives.

I don’t expect to live to see it happen.

The rough endoplasmic reticulum is a cell structure that consists of folded membranes that contain ribosomes. What is the advant
attashe74 [19]

Answer:

B

Explanation:

The folds contain ribosomes attached to the membrane. The more the folds the more the surface area to which more ribosomes can attach. The ribosomes are organelles responsible for the manufacture of protein in cells. Thereafter, the proteins are properly folded by the mediation of chaperones in the lumen of the RER.
