Answer:
you expect to see that 75% of your F2 generation rabbits have floppy ears and 25% of your rabbits have black fur.
Explanation:
<u> Available data:</u>
- Two true-breeding groups of rabbits.
- The first group has floppy ears and white fur.
- The second group has straight ears and black fur.
- 100% of the F1 generation has floppy ears and gray fur.
- Each of these traits is determined by a single gene and undergo independent assortment.
Having this information we can infer that floppy years, expressed by F allele, might be dominant over straight ears, expressed by f allele. And that the fur color is affected by incomplete dominance, being B the allele expressing black color, b the allele expressing white color and Bb the genotype for grey color.
Incomplete dominance is a condition where neither of the alleles completely dominates over the other one. Descendents possess an intermediate phenotype between the two parental phenotypes and not the dominant one.

BINARY FISSION
Answer:
Option b. Lowering the pH to kill pathogenic bacteria is correct answer.
Explanation:
bacterial motors are sensitive to pH. By decreasing the pH bacterial motors stops working. This was identified in a new research. But, with the weak acids and a lower internal pH they slow and ultimately stop moving (became dead).
