Answer:
Mitochondria are famed as the energy factories of eukaryotic cells, the seat of an array of membrane-bound molecular machines synthesizing the ATP that powers many cellular processes.
 
        
             
        
        
        
It might knock the old theory away completely because all of the new knowledge doesn't support the theory or it could change it because some of the new information supports the old stuff.

Answer:
- Option D is the correct answer. 
Explanation:
It is given that a 2 kg ball is traveling at a speed of 4 m/s, so we have to find its kinetic energy. 
KE = 1/2 mv²
KE = 1/2 × 2×(4)²
KE = 1/2 × 2×16
KE = 16 J 
<u>Some information about Kinetic Energy</u>.
Kinetic Energy is the energy an object has because of its motion. It is directly proportional to the velocity of the particle and its mass. Kinetic energy is given by, 
- KE = ½mv²
- It occurs due to the motion of the particle.
- If a particle at rest position, then the kinetic energy will be zero because that particle won't be accelerating.
