bio? anyone out there to help me..?? pleaseeeeee.. i am so going to FAIL!!?

Question

an artifical cell with an aqueous solution in a a selectively permeable membrane has just been immersed in a beaker containing a different solution.

Inside the cell, there is .03 M glucose and 0.2 M sucrose and in a beaker, it is .01 M sucrose, .01 glucose, and .01 M fructose

the question is : which solutes will exhibit a net diffusion into the cell?
A Glucose
B Sucrose
C Frcutose
D both b and a

2 Question: after the cell is placed into the beaker, which of the following changes would occur?

A. the artifical cell would become more flaccid ( weak)
b. The artifical cell would become more tugid
C. the membrane potenital would decrease
D. the entropy of the system ( cell plus surrounding solution ) would decrease

all the help would be appreciated

thanks guys

Answer 1

1) "C" appears to be the most reasonable answer.

2)Looks like the system is hypotonic to the cell and will
therefore cause an inward osmosis. Answer is "B".

Answer 2

1. I don't know. If the membrane is permeable to fructose, then the answer is
C. Fructose.

The principle here is that fructose has a greater concentration outside the cell than inside.

2. Again, I don't know. Let's say that the membrane is impermeable to sucrose. If that's the case, then the answer is
B The artifical cell would become more turgid
The reasoning is that there's a greater concentration of solutes inside the cell, the solute (sucrose) can't diffuse out, and water can diffuse in... and water will diffuse inward (osmosis).

Answer 3

i visit be brutally straightforward here to your guy or woman solid: it's time to alter your important. I say that not because of the fact it kills your probabilities of ever entering into med college. that is nevertheless accessible to get into med college with that checklist as long as your technological know-how GPA gets as much as a first rate point (a minimum of three.5), you get in some solid learn or scientific experience, and otherwise develop a great med college application. fairly the reason I say which you may desire to alter your important is via the fact introductory biology is as hardship-free because of the fact the pre-med music gets. in case you won't be in a position to deal with it, there is not any way which you would be waiting to deal with the plenty greater durable training that come after it (heavy emphasis on the "plenty" in "plenty greater durable"), to assert not something of the insane difficulty of the educational in med college. in addition to, you're 2 years at the back of on your important. so as to graduate in a first rate quantity of time you will could desire to load up on technological know-how training for many of your college occupation. lower back, in case you are going to be able to desire to not cope with intro bio you is only not waiting to deal with 4-5 bio training concurrently. the explanation why I pronounced being this straightforward is to your guy or woman solid is in view which you have not have been given perpetually interior the international, and the faster you elect for a clean important the greater beneficial off you would be. I recommend which you're taking your summer season harm to perform a little reflecting and determine what else pastimes you.
