Is hypertonic active or passive transport
Len [333]

I'm a little confused by this question. Hypertonic just means that something has more of something than another thing. For example, if you place a cell in a solution, and 2% of the cell is made out of something while the solution is made out of 40% of the same thing, the solution would be hypertonic to the cell. Sorry if that explanation doesn't make sense, I tried my best lol.

Although I'd assume the answer is passive transport as anything that is hypertonic to something else will diffuse down its gradient in an attempt to reach a balance.

A DNA sample contains 30% cytosine. What percentage of the sample would be thymine?
julia-pushkina [17]

Answer:

30% Thymine

Explanation:

If 30% of Adenine is present, it would be reasonable to assume that 30% of Thymine will be present, as the ratio between the two complementary nitrogenous bases will be roughly equal.

Therefore, that leaves us with 40% between Cytosine and Guanine. Since the ratio between them would be equal, it gives us 20% of Cytosine and 20% of Guanine.

<u>Therefore:</u>

30% of A + 30% of T + 20% of C + 20% of G = 100% DNA

Raw shell eggs must be received in refrigerated equipment that keeps them at a temperature of _______ or less. 41°f 45°f 50°f 70
kow [346]
The correct answer is forty-five (45) degrees Fahrenheit.

Raw Shell Eggs are received in 45 degrees fahrenheit refrigerators to prevent the yolks from drying out and to preserve their freshness. Raw Shell Eggs should be handled carefully, since they are fragile and one must also take precautions when handling raw eggs, since they may hold salmonella, but it is less likely to occur.
