Answer:
Species could go extinct when their environment changed if they could not adapt to the change.
Vinegar is an extremely acidic liquid. Very few microorganisms (ie bacteria and fungus which cause foods to spoil) can survive in such an acidic environment. Among other effects, it can destroy their cell walls, and prevent their own enzymes working (enzymes are extremely pH sensitive). There are a small number of microorgamisms which are adapted to survive in extreme acidity. However, this adaptation prevents them from surviving in more 'normal' environments. Therefore, anything which can survive in the vinegar, will not likely survive on your kitchen surface, and the same is true the other way around. Therefore, as vitually nothing can colonise whatever is in the vinegar, the food will be very effectively preserved. . . . . . . . . . . you can say........................ . . the low pH a nd high acidity of vinegar destroy bacteria

The term is called a theory.
In scientific investigation, a theory is a well substantiated explanation of how a particular phenomenon works based on the set of facts which had been repeatedly confirmed through observations and experiments. A scientific theory gives reliable account of a phenomenon.
Answer:
32 different gametes can be produced
Explanation:
The possibilities of formation of the number of different gametes in a population are determined by the number of heterozygous alleles for a given gene in the organism.
The formula to calculate the number of gametes is- 2ⁿ where n represents the number of heterozygous alleles
In the given question, the five genes of the organism are considered which form five type of heterozygous allele like A, a, B,b and so on. Therefore five types of heterozygous alleles is possible.
So using the formula we have 2⁵= 32 gametes.
Thus, 32 gametes is correct.
