Answer:
The cell walls observed by Hooke gave no indication of the nucleus and other organelles found in most living cells. The first man to witness a live cell under a microscope was Anton van Leeuwenhoek, who in 1674 described the algae Spirogyra. Van Leeuwenhoek probably also saw bacteria.
Explanation:
The kinetic energy of a car with a mass of 1,324 kilograms, traveling at a speed of 20 meters seconds is 264800J.
<h3>How to calculate kinetic energy?</h3>
The kinetic energy of a moving car can be calculated using the following formula:
K.E = ½ × m × v²
Where;
- K.E = kinetic energy
- m = mass
- v = velocity
K.E = ½ × 1324 × 20²
K.E = 264800J
Therefore, the kinetic energy of a car with a mass of 1,324 kilograms, traveling at a speed of 20 meters seconds is 264800J.

Answer:
The change in PH not only effect the shape of enzymes, but it may also change properties the of substrate so that that substrate cannot control to bind the active site and it cannot undergo catalysis.
In general enzymes have a PH optimum. However this optimum is not same for each enzyme.
Explanation:
For Example; The enzyme pepsin is most active at an acidic PH, Whereas the enzyme trypsin performs best at slightly alkaline PH. the increase or decrease in PH can change the concentration of ion in a solution
