Answer:
Kettlewell thought that if natural selection caused the change in the moth population, the following must be true: Heavily polluted forests will have mostly dark peppered moths. Clean forests will have mostly light peppered moths. Dark moths resting on light trees are more likely than light moths to be eaten by birds.
I believe i the correct answer is c because he notices that some of the traits weren't being passed on.

Coral Bleaching is hazardous to fish because It leaves fish and corals vulnerable to deseases.And the average temperature of tropical oceans increases by 0.1 degrees C, over the past century.Fish are affected because, most fish in the ocean live in coral reffs, which end up dying, and leaving its habitant fish without a home.
I) Alleles is the alternative form of a gene or in other terms the variant form of a gene. If there are two alleles at a locus p and q are used to represent their frequencies. Frequencies of all alleles in a population will add up to 1.
Therefore, in this case if red allele CW is p=0.7, then the frequency of the white allele in this population (q) is 0.3.
ii) From the punnet square the expected genotypes frequencies in the offspring generation will be 0.49 CRCR (red flowers, o.42 CRCW (pink flowers) and 0.09 CWCW (white flowers).
