Protection Mechanism I: temporal
What will be an ideal response?
•Single-celled cyanobacteria found in open ocean (e.g. Synechococcus and Prochlorococcus).
•Separation of phototrophy and nitrogen fixation in time (temporal).
-During the day, oxygenic phototrophy generates ATP and reducing power.
-Nitrogen fixation is then carried out at night.

Benign positional vertigo is due to
A. the formation of particles in the cochlea. These particles will stimulate the stereocilia producing a sensation of movement when there is actually no movement. B. the formation of particles in the semicircular canal resulting in an inner ear infection. C. the formation of particles in the malleus.
