Answer:
Consider the heterozygous oval, thick cell walled bacteria to have the alleles OoTT and the thin cell walled bacteria to have alleles oott. Results will be 50% oval, thick walled bacteria and 50% round, thick walled bacteria. This will be the F1 progeny.
When the oval, thick walled bacteria from the F1 progeny is cross bred with round, thick walled bacteria then 25 percent of the bacteria will be heterozygous oval, thick walled. 25 percent will be heterozygous oval and heterozygous thick walled. 25 percent will be round and thick walled. 25 percent will be round and thin walled.

Explanation:
Algal bloom is a term used to describe the excessive growth of algae species in a water body. This excessive growth or proliferation is as a result of the exposure to nutrient in form of pollutants, a process called Eutrophication.
However, the presence of an algal bloom indicates the pollution of that water body, which will result in the degradation of the pollutants by bacteria. As bacteria acts on the pollutants in the water body, they excessively use the dissolved oxygen of the water body, hence, drastically reducing the oxygen levels of the water. This possess a great threat to aerobic wildlife in the water, which could die as a result of suffocation or anorexia.
Hence, the most important thing to do in a case of noticing an algal bloom in a bay is to evacuate all wildlife from the bay in order to prevent mass death.
Indigenous peoples are important in environmental considerations because:
a. their homelands contain natural habitats least disturbed by humans.
b. their homelands contain a huge proportion of earth's biodiversity.
c. their languages represent encoded knowledge of nature that is irreplaceable.
d. all of the above are correct.
D. seems to be the best answer.
