Answer:D
Explanation: The pulmonary air sacs of birds only permit a unidirectional flow of air through the lungs. Unidirectional flow means that air is inhale and exhale through one trachea alternatively. This means the bird lungs only receive largely fresh air which has a high oxygen content during inhalation and do not receive fresh during exhalation. While air flow bidirectional in mammals.
A swimmer sprints a short distance for competition. The swimmer is not able to take in enough oxygen to make the ATP needed for the sprint. Which of the following processes is most likely going to occur in the swimmer's muscle cells during the competition? (2 points)
A. Aerobic respiration would continue until oxygen is no longer available, leading to cell death.
B. Aerobic respiration will continue to make the same amount of ATP since oxygen is not required.
C. Anaerobic respiration would be used to produce small amounts of ATP in the absence of oxygen.
D. Anaerobic respiration will produce more ATP than the process used in the presence of oxygen.
<u>Answer:</u>
A swimmer sprints a short distance for competition. The swimmer is not able to take in enough oxygen to make the ATP needed for the sprint. Anaerobic respiration would be used to produce small amounts of ATP in the absence of oxygen and it is the process happens in the swimmer's muscle cells during competition.
<u>Explanation:</u>
- A Swimming sprinter will spend his maximum energy while to cover a short distance in his competition. Quickly he will reduce his oxygen level.
- Oxygen will produce an ATP molecule (Adenosine Triphosphate) which is required for a sprinter.
- The ATP molecule will produce energy for the cells. Aerobic respiration takes place only when in the presence of oxygen.
- While swimming they will not get enough oxygen so the Anaerobic respiration takes place to produce ATP molecule.
