Question 14
Chargaff discovered that the percentage of thymine bases equaled that of adenine and conversely that cytosine equaled guanine. Solve the following problem. A sample of DNA reveals that there is 37% of thymine. How much cytosine will there be in this sample?

a. 13% cytosine
b. 37% cytosine
c. 74% cytosine
d. This problem is unsolvable

Its 13 percent

Explanation:

Since thymine equals adenine, adenine equals 37. So you add 37 to 37 which is 74. then subtract it from one hunnid, which is 26. Then divide that by 2 since cytosine is equal to guanine. so you'll have cytocine is 13 percent and guanine is 13 percent as well.

who knows

explanation:

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
