Answer:
the backbone of DNA contains deoxyribose, where as the backbone of RNA contains ribose.
Explanation:
As the cells run out of oxygen they switch to anaerobic respiration, which allows the cell to make small amounts of ATP in the absence of oxygen; when the weightlifter’s muscle cells are not able to take in enough oxygen to make very much ATP, as he competes in the event.
Explanation:
Anaerobic respiration takes place when there is too low or no oxygen to perform aerobic respiration. This transfers the energy to the cells from glucose. It produces energy very quickly along with lactic acid and other waste products.
Anaerobic respiration is highly useful when short bursts of energy are required very quickly to energize the muscles to perform high intensity activities like wrestling, weightlifting, intense short workouts, etc.
Lactic acid fermentation causes the muscles to burn out when high intense short burst physical activities are performed.

Answer:
Active transport mechanisms require the use of the cell’s energy, usually in the form of adenosine triphosphate (ATP).
Explanation:
If a substance must move into the cell against its concentration gradient, that is, if the concentration of the substance inside the cell must be greater than its concentration in the extracellular fluid, the cell must use energy to move the substance. Some active transport mechanisms move small-molecular weight material, such as ions, through the membrane.
In addition to moving small ions and molecules through the membrane, cells also need to remove and take in larger molecules and particles.
