Answer:
E. are found in nitrogen-fixing cyanobacteria AND are used to protect nitrogenase.
Explanation:
Heterocysts are specialized cellular compartments found in nitrogen fixing cyanobacteria. They provide the ideal anaerobic environment for nitrogen fixation since nitrogenase enzyme cant work in presence of oxygen. Hence, in a cyanobacteria both the oxygen requiring photosynthesis process and the oxygen sensitive nitrogen fixation process takes place simultaneously.
Heterocysts have an additional cell wall made of glycolipid that provides a hydrophobic barrier to oxygen. They are involved in production of nitrogenase and other proteins that are required for nitrogen fixation. They also degrade photosystem II which is responsible for producing oxygen and produce proteins which remove any remaining oxygen.

Answer:
White eyes are lethal in male Drosophila was the hypothesis of Thomas hunt which was valid. Hence the answer is option B.
Explanation:
Thomas hunt Morgan was a famous American biologist. He was more famous because of his experiment on drosophila which contributed most of things about the lifestyle and health science in much of the findings about those insects.
He was also awarded by the Nobel prize for his works which was related to medicine in 1933. He has also contributed many knowledge about the chromosome and heredity. he is finding is very helpful nowadays for the scientist and other biologist.
