A researcher is studying a strain of mice that only incorporate 50 percent of the necessary iron into their hemoglobin molecules

. Which of the following statements is likely true regarding these mutant mice?
A. Because oxygen cannot dissolve in the blood directly, no oxygen will be transported in the bloodstream of these mice.

B. The hemoglobin in these mutant mice will be unable to bind oxygen molecules, because iron-containing heme groups are responsible for the binding of oxygen to hemoglobin.

C. The hemoglobin in these mutant mice will be able to bind half the number of oxygen molecules compared to the hemoglobin of normal or wild-type mice.

D. The hemoglobin in these mutant mice will be able to bind more oxygen molecules compared to the hemoglobin of normal or wild-type mice.

E. There will be no difference between the amount of oxygen transported in the bloodstreams of these mutant mice compared to the amount transported in normal or wild-type mice.

Answer:

Option (c).

Explanation:

The hemoglobin is the important protein present in the red blood cells. The hemoglobin molecules helps in the transport of oxygen and carbon dioxide in the body.

The iron is important for the hemoglobin molecule formation. The deficiency in the iron can cause the abnormal hemoglobin structure. The mice hemoglobin can binds with the only 50% of the oxygen molecules as compared with the wild type mice.

Thus, the correct answer is option (c).

Pavlova-9 [17]

Answer:

<u><em>C. DNA from the S bacteria is necessary for bacterial transformation to occur.</em></u>

Explanation:

These series of experiments determined that DNA is the genetic material which gives rise to a particular type of cell. As we can see, the S bacteria with degraded proteins were able to grow when the proteins and RNA were degraded. But they were not able to grow when their DNA was degraded. This experiment proved that proteins or RNA are not the genetic material, rather DNA is the material related to inheritance.
