Will ! a cell containing a 3% sucrose solution is placed into a beaker containing a 7% sucrose solution. assume the cell’s membrane is permeable to water, but not permeable to the sucrose. where will the water diffuse? explain.

A cell containing a 3% sucrose solution is placed into a beaker containing a 7% sucrose solution. Assume the cell's membrane is permeable to water, but not permeable to the sucrose.

{Hope it helps!}

The water will diffuse from the 3 % sucrose solution to the 7 % sucrose solution until the two solutions are isotonic.

Explanation:

One definition of osmosis is that it is the movement water molecules from a region of higher water potential to a region of lower  water potential through a partially permeable membrane. Water potential can be though of as the ability of molecules to move freely. They move more freely in 3 % sucrose solution because there are fewer solute particles. So water will diffuse from the 3 % sucrose solution to the 7 % sucrose solution until the two solutions are isotonic.

hello there,

guys i’m confused.

which rock will weather faster?

answer: b rock

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.
