since this is a repulsion force so it must be a negative charge
Part b)
As per Newton's III law it will exert equal and opposite force on it

Let's examine each organelle and its function.
A. The Nucleus
This organelle is the control center. It regulates a cell's activities and processes. It also contains the DNA or genetic information.
B. The Cytoplasm
The cytoplasm is a jelly like liquid that fills the inside the cell. Organelles and molecules are suspended in it.
C. The Mitochondria
This is also called the powerhouse of the cell, because it <u>produces energy!</u> This is the site of cellular respiration, the process that turns oxygen and glucose into ATP (energy), water, and carbon dioxide.
D. The Cell Membrane
This covers and protects the entire cell. It keeps important substances in and allows them to enter the cell, while preventing harmful ones from entering.
Based on this information, we see that the <u>mitochondria</u> is the organelle producing energy for the cell and <u>choice C</u> is correct.
