They breathe through their skin. Air dissolves on the mucus of their skin, so they MUST stay moist to breathe. If worms dry out, they suffocate. As fresh air is taken in through the skin, oxygen is drawn into the worm's circulatory system, and the worm's hearts pump the oxygenated blood to the head area.

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)
