You times all of them together and you would get the answer

Answer:
dyes used in negative staining have an. acidic chromagen (negatively charged chromophore) Examples of negative stains. NIgrosin and eosin. heat fixing smears can.
A control group of the experiment is the one in which no treatment or intervention is given. So, in your case, the pea plants in which was not subjected any of the fertilizers, will serve as a control group. This is a negative control. A positive control group is the one in which an established treatment is given, which definitely leads to the production of the desired character. So, in your case, a very good well-known fertilizer which has a positive control on the growth of the pea plant, would serve as a positive control.
A change in temperature affects an enzyme by causing the enzyme to change it's shape.
<h3>what is an enzyme?</h3>
An enzyme is a substance that catalyzes chemical reactions.
- Temperature is one of the major factors that aid enzymes action.
- Increase in temperature could increase the rate of enzyme.
- However, at a very high temperatures, the enzyme can be denatured thereby changing it shape or structure and the enzyme may no longer bind to the substrate or function effectively this will then reduce the rate of chemical reaction.
Therefore, a change in temperature i.e very high temperature can change the shape of an enzyme.
