Fluorescent in situ hybridization (Fish) is a method employing a fluorescent dye covalently bonded to a specific nucleic acid probe identifying or tracking organisms in the environment. Fluorescent in situ hybridization (fish) can be used to determine; how many salmonella typhimurium cells are present in a sample of unpasteurized apple juice, the phylogenetic diversity of an environmental sample and also whether a specific piece of mRNA is being produced.
Answer: Plants need animals for seed dispersal and pollination. ... Some animals eat plants. Some animals eat other animals. When animals die and decompose, the plants use the nutrients that were deposited back into the soil from the decomposing organism.

Explanation:
A heterozygous type can be described as the type in which both the alleles of a gene are different. If both the alleles of a gene are similar in an organism, then the person is said to be homozygous for the trait.
In the above question, two heterozygous parents are to be cross- bred to check the probability of them producing homozygous alleles (AA).
A punnet square made will show the following results:
A O
A AA AO
B BA BO
Hence, there will be 25% chance that the offspring produced could be homozygous AA.
Enzymes work best within specific temperature and pH ranges, and sub-optimal conditions can cause an enzyme to lose its ability to bind to a substrate. pH: Each enzyme has an optimum pH range. Changing the pH outside of this range will slow enzyme activity. Extreme pH values can cause enzymes to denature.
