Answer options:
- The nucleus was unable to provide instructions for the other organelles in the cells.
- The mitochondria were unable to undergo cellular respiration and could not produce energy for the cells to function.
- The lysosomes were unable to remove waste from the cells.
- The cell membrane was unable to allow substances to enter and exit the cells.
Answer:
- The mitochondria were unable to undergo cellular respiration and could not produce energy for the cells to function.
Explanation:
Mitochondria are the site of aerobic respiration. This is the process that produces energy in the form of ATP. ATP provides energy for all cellular processes. Without this energy, the cell cannot carry out its functions and will quickly die.
Aerobic respiration requires a good supply of oxygen, which the grasshopper would not have had in a sealed container.
The correct answer is letter (<span>C) The polar air mass moves south to replace the rising maritime tropical air mass.</span> These air masses are bringing cold air to warmer areas most especially during the winter and cool. These air masses are stable and usually does not form much cloud. While the Continental Polar air move down south, across the warmer land, the lower part of the air mass is modified and thus few clouds are formed.
