Answer:
The correct answer would be:
A G C T
Human: 31 19 19 31
Cow: 28 22 22 28
Salmon: 29 21 21 29
Wheat 27 23 23 27
Yeast 31 19 19 31
Explanation:
According to the rule of Chargaff which states or explains the amount of the A, T, G, and C bases in the DNA molecule. It says that the DNA of any organism should have a pyrimidine and purine ratio of 1:1. This means the amount of A would be equal to T and the amount G should be equal to the amount of C.
It also says that the amount of a and G would be equal to the amount of C and T. So on the base of this we can find the missing value in the table:
A G C T
Human: 31 19 19 31 (A= T and G=C)
Cow: 28 22 22 28 (A= T and G=C)
Salmon: 29 21 21 29 (A= T and G=C)
Wheat 27 23 23 27 (100 - A+T = G+C)
Yeast 31 19 19 31 (A= T and G=C)
The answer is C or B.
If it was permeable water and other substances could get through.
And hard? That is one of those answer choices teachers throw in to try and make an obvious elimination choice.
