Answer:
The Hardy-Weinberg model states that a population will remain at genetic equilibrium as long as five conditions are met: (1) No change in the DNA sequence, (2) No migration, (3) A very large population size, (4) Random mating, and (5) No natural selection.

GAU to GAC is least likely to change phenotype of an organism.
<h3><u>Explanation</u>:</h3>
Phenotype of an organism is defined as the physical characteristics of an organism. This phenotype is dependent on the genotype of the organisms. This means the phenotypic characters are actually the expressions of the genes of the organisms. Now the genes are expressed in form of codons that are the three nitrogen base sequences. Each codon codes for a particular amino acid which in turn polymerises to from the protein which actually forms the phenotype of the organism.
Now there are 20 amino acids and 64 codons. Thus there are more than 1 codons for a single amino acid. So, if a codon is replaced by another codon which codes for same amino acid, then the phenotype is least likely to be affected.
Both the GAU and GAC codes for aspartic acid. So the phenotype won't be affected much by this mutation
A) water is not formed during this process
Answer:
I'm not too sure specifically for 9th grade. Though I am in 12th grade right now and currently using the Edrolo biology textbook which is solely based on the key dot points/skills for the entire subject. They also include past exam questions or similar exam style questions both multiple choice and short answer for each topic and chapter within the book.
