Answer:

B. At what rate do the mitochondria of the cell need to convert glucose to usable energy molecules to meet the high energy needs of the cell?

Explanation:

Organelles are specific in their functioning and hence, each organelle contributes its own quota to the cell's proper functioning. According to the question, a muscle tissue is being worked on to determine the effect of a missing or damaged organelle on its cell.

Mitochondria are organelles found in all eukaryotic living cells. They are the organelles responsible for the synthesis of ATP (energy) used by the cell as a result of the glucose that gets converted in them during cellular respiration.

Therefore, to determine if the muscle cells are functioning properly, the question that: At what rate do the mitochondria of the cell need to convert glucose to usable energy molecules to meet the high energy needs of the cell? should be asked.

Note that, Chloroplast and cell wall are not found in muscle cells, which is an animal cell. Likewise, ribosomes are not organelles for synthesis of glucose.

How many red blood cells does your body make and kill in a seccond?
Andru [333]
 The average red blood cell lives for 120 days.

2. There are 2.5 trillion (give or take) of red blood cells in your body at any moment. To maintain this number, about two and a half million new ones need to be produced every  second by your bone marrow.That's like a new population of the city of Toronto every second.

3. Considering all the tissues and cells in your body, 25 million new cells are being  produced each second.That's a little less than the population of Canada - every second !

4. A red blood cell can circumnavigate your body in under 20 seconds.

5. Nerve Impulses travel at over 400 km/hr (25 mi/hr).

6. A sneeze generates a wind of 166 km/hr (100 mi/hr), and a cough moves out at 100 km/hr(60 mi/hr).

7. Our heart beats around 100,00 times every day.

8. Our blood is on a 60,000-mile journey.
