Snezhnost [94]

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)

Clay and other materials through which water cannot readily pass are
ale4655 [162]

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.

I hope I have helped!

What if there were too many rabbits in this ecosystem?
musickatia [10]

Answer: Prey for the rabbits would decrease greatly; there would be less food for the frogs and voles, so their populations would decrease. This means less food for the foxes and hawks.
