I also believe the answer is A.
Answer:
(D) Strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration.
Explanation:
As Frida was exercising, her muscle cells were undergoing a frantic pace of metabolism (contraction and relaxation), where oxygen supply did not supply the required effort, thus causing muscle fatigue and heavy breathing.
Physical activity is synonymous with moving muscles. The more muscle fibers strive to accomplish a task, the more they consume the oxygen brought into the bloodstream. When this occurs, the body begins to breathe hard as lactate is transported to the liver.
This forces the lungs to work at a fast pace, as they are responsible for oxygenation. The heart also speeds up because it needs to pump blood more vigorously. This is why during exercise the heart rate and breathing rate increase and we breathe heavily.
Answer:
they are stronger and faster.
Explanation:
The correct answer is that variable number repeats are used in DNA tests; they have hundreds of possible lengths. Eye color is determined by variations in a person's genes. Most of the genes associated with eye color are involved in the production, transport, or storage of a pigment called, melanin. Eye color is directly related to the amount and quality of melanin in the front layers of the iris.
Answer:
Mitochondria is the organelle where cellular respiration takes place. Cellular respiration can be described as a process in which oxygen and glucose are converted into carbon dioxide and water along with the release of ATP. This reaction can be written as:
Glucose + Oxygen → Carbon dioxide + Water + ATP molecules
C6H12O6 + 6O2→ 6CO2 + 6H2O + ATP
The ATP made can be broken down so that energy is released.
ATP + H2O → ADP + Pi + free energy
