The answer is because it lowers the number of chromosomes in half, ensuring that the fusion will have the appropriate amount of chromosomes after the fusing of the sperm and the egg.
Petri dishes should always be stored inverted.
In biology, petri dishes are frequently used to produce microorganisms like bacteria, yeast, and mold. The organisms that grow on solid or semisolid surfaces are best suited for it. To reduce the chance of contamination from airborne spore particles landing on them and to avoid the buildup of water condensation that could disrupt or impair a culture, they are often covered and stored inverted.
Aside from that, incubating the media in the normal position could result in the media drying out, which would interfere with the ideal conditions for microbial growth and increase microbial count mistakes. Since the labels are put underneath the plates rather than on the lids, placing plates upside down also makes them easier to handle and recognize.

Answer:
the answer is C
Animals get the nitrogen they need by eating plants or other animals that contain nitrogen. When organisms die, their bodies decompose bringing the nitrogen into soil on land or into ocean water. Bacteria alter the nitrogen into a form that plants are able to use
<u>ANSWER:</u>
"Reduced concentration of substrate" available can interfere with the "ability of an enzyme" to catalyse a reaction. The main use of enzymes is to increase "the rate of reactions".
<u>EXPLANATION:</u>
- There are several factors that have an impact on the ability of an enzyme to catalyse a reaction.
- These include temperature, pH levels, and the quantity of substrate as well as the reactant. When the "substrate concentration increases", the rate of the reaction also increases in the presence of an enzyme.
- On the other hand, when the "substrate concentration is low", the enzyme cannot catalyse the reaction at a fast rate.
