For the first question, i think the correct answer is A. Normal cells undergo apoptosis while cancer cells don't. For the second question, The answer is option B.<span> </span><span>Cell division has two checkpoints namely, G1
checkpoint and spindle assembly checkpoint. The checkpoint which determines if
division has properly occurred is the G1 checkpoint. At this point, is a damage
in the DNA is detected or the has not reach the optimum size, the cell is
stopped in G1 and is not allowed to proceed to further process.</span>
The correct option is (C) Carbon dioxide reacts with an amino group to stabilize the deoxyhemoglobin state.
In addition to transporting oxygen from the lungs to the tissues, hemoglobin is also involved in transporting carbon dioxide from the tissues to the lungs where, Carbon dioxide reacts with an amino group to stabilize the deoxyhemoglobin state.
<h3>How does hemoglobin contribute to the movement of carbon dioxide from the tissues to the lungs?</h3>
- The transport of carbon dioxide in the blood is influenced by a number of factors. First, blood contains more carbon dioxide soluble molecules than oxygen. The plasma contains 5–7% of the total dissolved carbon dioxide.
- Second, carbon dioxide can enter red blood cells and bind to hemoglobin or it can bind to plasma proteins. In this form, 10% of the carbon dioxide gets transported.
- A substance known as carbaminohemoglobin is created when carbon dioxide binds to hemoglobin. Hemoglobin and carbon dioxide can bind to one other again.
- As a result, when it gets to the lungs, the carbon dioxide can separate from the hemoglobin without restriction and leave the body.
- Third, the bicarbonate buffer system is responsible for transporting 85% of the carbon dioxide molecules.

I understand that the question you are looking for is "In addition to transporting oxygen from the lungs to the tissues, hemoglobin is also involved in transporting carbon dioxide from the tissues to the lungs. How is this accomplished?
A. Carbon dioxide competes for the oxygen-binding site on the heme.
B. Carbon dioxide competes for the 2,3-BPG-binding site.
C. Carbon dioxide reacts with an amino group to stabilize the deoxyhemoglobin state.
D. Carbon dioxide binds to the carboxyl terminus of hemoglobin."
