Chemicals can make mutations by a number of mechanisms. Base
analogs are incorporated into DNA and mostly pair with the wrong base.
Alkylating agents, deaminating chemicals, hydroxylamine, and oxidative radicals
change the structure of DNA bases, thus altering their pairing properties.
Introducing agents wedge between the bases and cause single-base insertions and
deletions in replication.
Answer: c. signal amplification
Explanation:
The uncoupling of the G-protein and inhibiting of the signal amplification are the two affects of the pertusis toxin. It is released by the bacteria called <em>Bordetella pertusis. </em>The G-proteins are affected by the action of pertusis toxin. The production to the excess level of cAMP due to the conversion of ATP into cAMP the ribosylation of the ADP molecules occurs due to pertusis toxin. This leads to the damage of G-proteins.
Answer: Nervous system
Explanation:
The cerebellum of the brain is the structure of the nervous system known to control various muscles of the body that are involved in involuntary activities such as breathing.
Thus, the nervous system controls and regulates a person's breathing
