Answer:
The correct answer is C. A buildup of lactic acid in the tissues.
Sore muscles after vigorous exercise are the result of lactic acid accumulation in the muscles.
Vigorous exercise reduces the levels of oxygen available in the muscles due to which complete oxidation of the glucose could not take place.
Muscle cells switch to another process called as lactic acid fermentation to produce energy. In this process, lactate dehydrogenase converts pyruvate into lactate and reduces NADH to NAD⁺.
This NAD⁺ enables the continuation of glycolysis which results in the production of net 2 ATP.
In addition, influx of materials such as nutrients, WBC, anti-inflammatory compounds etc into the muscle cell (for repair) causes swelling of the muscle fibers which is also the reason for the muscle soreness.
Answer:
This difference indicates that the results are precise but not accurate
.
Explanation:
Precise results are those that are very close to the actual result, but do not achieve exactly the same result. In addition, this difference between the precise results is exactly the same. We have an example of this in the case shown in the figure above, where the blood pressure readings measured by the cuff differ by 15 points for each reading. This case also shows us that the results are not accurate, because this type of result is one that shows a result exactly the same as the real one.
The respiratory system consists of all the organs involved in breathing. These include the nose, pharynx, larynx, trachea, bronchi and lungs. ... The nose, pharynx, larynx, trachea and bronchi all work like a system of pipes through which the air is funnelled down into our lungs.
