Answer:
c. A piece of mesh, keeping some things out and letting some things in
Explanation:
The cell membrane of a cell is described as "selectively permeable". Permeable means things can go through it, but the word selectively is the important part. It lets things in, but it also keeps things out. This way it can regulate the different things that go in and out of the cell. It allows certain molecules that provide the cell nourishment and other things that help it function, and at the same time, it allows waste to move out of the cell. Not all needed molecules can go through the "mesh-like" membrane, that why some of them need help.
Answer:
A. DNA is transcribed into RNA, which is translated into protein
Explanation:
Answer:
1.292 M
Explanation:
<em>In order to calculate the concentration of H2SO4, we need to get the balanced equation of reaction first;</em>
Using the formula:
CaVa/CbVb = na/nb
where Ca = concentration of acid, Va = volume of acid, Cb = concentration of base, Vb = volume of base, na = number of moles of acid, and nb = number of moles of base.
In this case, Ca =?, Va = 10.00 ml, Cb = 0.777, Vb = 33.25 ml, na = 1, nb = 2
Ca = CbVbna/Vanb = 0.777 x 33.25 x 1/10 x 2
Ca = 1.292 M
Hence, the concentration of H2SO4 is 1.292 M
The answer I believe is C. T turns into A. A turns into U, and so on
I think the answer is c
hoped i helped
