Answer:
c. Cardiac muscle contains bands like skeletal muscle, but its contractions are involuntary like smooth muscle.
Explanation:
In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Cardiac muscle is also referred to as myocardium and it's one of the three (3) muscles found only in the heart of vertebrates, the other two (2) being smooth muscle tissue and skeletal muscle tissue.
Cardiac muscle contains bands like skeletal muscle referred to as sarcomeres (contractile units), but its contractions are involuntary like smooth muscle and it's typically being regulated by the sinoatrial node of the heart.
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."
Carbon (C) is an element
Carbon Dioxide (CO2) is a compound
Hydrogen (H) is an element
Sodium Chloride (NaCl) is a compound
A good way to tell whether something is a compound or an element, is that in a compound there is a mixture of different elements. Like in Carbon Dioxide, the symbol is CO2. This shows the carbon (C) and oxygen (O) together. I hope i worded that well enough and this helps :)
