BARSIC [14]

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.

4vir4ik [10]
The best time of day to water plants is in the evening or early morning. This is because water applied during the day, particularly at noon, will be most affected by evaporation by the sun's energy before it can soak into the soil. By watering during the evening or early morning, the water has a chance to seep into the soil to allow maximum availability to the roots of plants.
