Answer;
Activation energy
Explanation;
Activation energy is the least possible amount of energy (minimum) which is required to start a reaction or the amount of energy available in a chemical system for a reaction to take place.
Catalysts can lower the activation energy and increase the reaction rate without being consumed in the reaction. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
Answer: 1350J
Explanation:
To solve this, we are going to use the formula for calculating potential difference which is:
Potential difference (V) = Work done (W) / Total charge (C)
Therefore,
9 volts = Work done / 150
Work done = 150 × 9 = 1350J
Explanation:
Mitochondria is called the 'power house' because It is the site for respiration. It is also responsible for conversation of food to usable energy.
To help fight off disease and viruses
Answer:
M = 60x
M = 150x
M = 675x
M = 1455 x
Explanation:
In a microscope the total magnification is found by multiplying the magnification of the ocular (eye piece) and objective lens.
=Ocular magnification = 15x
=Objective magnification = 4x
Total magnification
M = 60x
M = 150x
M = 675x
M = 1455 x
