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.
Answer:
The factors which remained constant are as follows -
- material used as the membrane
- amount of substances used
- number of trials
The factors which have shown variation are as follows -
- molecule size (large starch molecules vs. small glucose molecules)
- whether the molecules diffused through the membrane (tubing)
Explanation
Some factors with in the experiments remained constant from the point of starting of the experiment to its end. While some factors were varied to study its impact on the experiment rate of progression or on the final product formed. Thus , out of the following given factors, the ones that remained constant are -
- material used as the membrane
- amount of substances used
- number of trials
The factors which have shown variation are as follows -
- molecule size (large starch molecules vs. small glucose molecules)
- whether the molecules diffused through the membrane (tubing)
Glucagon
This is a hormone that deals with blood sugar homeostasis. When blood sugar levels are low, glucagon is produced to convert the fats in the reserve back to glucose until normal levels are achieved.
Explanation:
Bone remodeling involves coordinations of osteoclasts and osteoblasts cells in the bone. The former breaks down bone tissue while the latter mineralizes bones. Calcium is the main ion in the body significant in mineralization of bone. Excess Ca2+ is stored in bone while low calcium levels in blood result in bone resorption.
Stress on a bone also causes increased mineralization to strengthen the bone against this stress. This is why astronauts when they go to space, due to less stress from low gravity, bone loses its mass. When they return back to earth, the bone readjusts to the increased stress from higher gravity by increased mineralization.
The hormone responsible for bone homeostasis is parathyroid hormone.

Answer:
Explanation:
An example of this analogy might be that the surrounding the central dogma which is compared to making yout mum's recipe for brownies.
First, you ought to call your mum, she stands for the DNA. Then, you pay attention in listening and copying down her instructions. This is can be compared to transcription because during transcription, DNA is copied to mRNA.
Any mistake you do during listening and copying leads to mutation caused by insertion or omission.
