The above statement is true.
<u>Explanation:</u>
During the oxidation of an amino acid through the Citric acid cycle or the Kreb’s cycle produces 2 ATP. Through oxidation of Glucose also 2 ATP molecules are obtained.
In the citric acid cycle the acetate is consumed along with water and the NAD+ is reduced to NADH with carbon dioxide as its waste product and stored in the form of chemical energy as two molecules of Adenosine triphosphate (ATP). In oxidation of glucose through glycolysis without the use of Oxygen 2 molecules of ATP is produced.
Carbon because in the carbon cycle it’s recycled by plants and animals continuously in the atmosphere where it can also turn into organic carbon in the ground.
In rheumatoid Arthritis patients, NK cell levels were abnormally elevated, possibly due to high serum levels of IL-2.
Rheumatoid arthritis (RA), is an autoimmune disease that means our own immune system attacks self healthy cells in the body by mistake, causing inflammation (painful swelling),mainly attacks the joints.
The given study is to investigate the relationship between serum interleukin-2 (IL-2) levels and disease activity.
This study also showed the relationship between absolute numbers of peripheral lymphocyte subsets, autoantibodies, and associated cytokines in patients with rheumatoid arthritis (RA).
The results showed that the number and percentage of NK cells were positively correlated with serum IL-2 levels so, IL-2 can be a reason for elevated level of NK cells

Answer:
b. The foot and ankle should be pointing straight ahead in a dorsiflexed position when it hits the ground
Explanation:
Dorsiflexion is a movement in the ankle where the toes point in an upward direction allowing for correct foot strike if done properly at approx. 15 degrees. As you run, dorsiflexing your foot puts it in an ideal position to absorb the shock of the landing while simultaneously tensing your muscles to spring forward into the next stride which allows a reduced ground contact time per stride, allowing you to run faster and more efficiently.
If a runner has poor dorsiflexion they may experience a ‘loose’ or ‘floppy’ foot due to relaxation at the ankle joint which results in striking the ground through the toes which causes poor force distribution resulting in injuries such as shin splints and runner’s knee.
