Enzymes can be denatured unfolded by heat or chemicals.
<h3>What are enzymes?</h3>
Enzymes are proteins that are found in living organisms which are able to increase the rate of chemical reaction and remains unchanged at the end of the reaction.
The factors that can denature enzymes include heat and chemicals. This is because:
- Higher temperatures disrupt the shape of the active site, which will reduce its activity, or prevent it from working. When the enzyme loses its shape, it is said to have been denatured.
- These environmental factors can alter the pH level of the enzyme.
Therefore, for an enzyme to perform its functions, the external factors that affects it's activities must be normal and favorable.

Answer:
Abiotic
Explanation: Water is not a living thing, therefore water is an abiotic factor.
Explanation:
D) 75 J
Energy is neither related nor destroyed- it's simply converted to different forms. Forces are vectors with both mass and acceleration; they are interactions that have the ability to change an object's motion. As objects move, their potential energy (apprx 100 J) is converted to kinetic energy. However, friction a resistive force, which is formed from the conversion of an object's kinetic energy into heat energy, as two surfaces move along each other.
With the reduction of friction, the energy output should increase, as less energy is lost as heat. Thus, the output should be 75 J.

Answer:
Neural stem cells are normally found within the brain and spinal cord. NSCs are specialized stem cells that can differentiate into the cell types of the central nervous system, including neurons and glial cells
Explanation:
B.
<span>Pesticides prevent the destruction of crops.
Pesticides have their advantages and strong disadvantages. With the dawn of science, scientists have unearthed biochemicals that can eradicate a set of pests that constantly bombard and hoard plants which are one of the source of food for humans. </span>
