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:
A unicorn is a mythical creature that resembles a horse with a horn on its forehead. The unicorn could use its horn for self-defense. Some unicorns might also have wings so they could help the unicorn survive by escaping predators quickly. W could be for a winged unicorn (dominant) and w would be a unicorn without wings (recessive). L could be for a long unicorn horn, and l could be for a short horn. C would be a lighter fur color and c would be a darker fur color. That's all I could come up with for now :)

Disturbances such as forest thinning, floods, fire and wind can all lead to secondary succession. Examples of secondary succession are the gradual replacement of old fields by forest or the vegetation recovery and change following wildfire occurrence.
