What are the primary mechanisms by which E. coli regulates the amount and activity of its heat-shock sigma H? a. gene inversion
b. proteolysis by chaperones
c. anti-sigma factors
d. RNA degradation
e. translational control
f. transcriptional controls

Option b (proteolysis by chaperones) and Option e (translational control) would be the correct options.

Explanation:

The other choices are given aren't linked to something like the scenario in question. So, the solution here is just the right one.

brain development. a child's brain undergoes an amazing period of development from birth to three—producing more than a million neural connections each second. the development of the brain is influenced by many factors, including a child's relationships, experiences and environment.
