The picture is really blurry I can’t see it
Answer:
Energy
Explanation:
Usually the inside of the cells is hypertonic to the extracellular matrix. This means there are more ions in the cell than outside. Therefore the cell requires energy to pump more ions into the cell against the concentration gradient. The sodium-potassium pump utilizes energy from ATP to pump Na+ and K+ ions 'uphill' into the cell.
Answer: Carbon dioxide
Explanation: Sugars and oxygen are broken down to produce ATP, and carbon dioxide is produced as a byproduct
Complete Question: In apneustic breathing, which is practiced by most marine mammals:
A. A small amount of air is kept in the lungs before diving
B. A large amount of air is kept in the mouth before diving
C. Normal breathing is maintained before diving
D. Several deep breaths are taken before exhaling and diving
E. No actual breathing takes place before diving
Answer: D. Several deep breaths are taken before exhaling and diving.
Explanation:
Common dolphins, whales and other marine mammals are known to undergo apneustic breathing. This breathing process is characterized by periodic or several breathe inhalation, followed by holding their breath and then exhaling them.
Marine mammals can afterwards, went on to dive. This process prevent high water loss out. Thus, they make fewer respirations while maximizing the amount of oxygen produced for optimal consumption.
