<u>Question</u>:
A substance that yields a cation plus the hydroxyl ion in water is a(n)
A) salt
B) acid
C) base
<u>Answer</u>:
A substance that yields a cation plus the hydroxyl ion in water is a(n) base.
<u>Explanation</u>:
Base is a substance that "donates electrons, accept protons, or releases hydroxide (OH-) ions" in aqueous solution .When a base is dissolved in water, it dissociates to give hydroxyl ions. Hydroxyl ion which is a negatively charged molecule and having one oxygen bonded to one hydrogen. In case of the base particles, when comes in contact with water becomes slippery as well as changes its colour. For bases, the pH value ranges from 8-14

AraC protein certain to the ara
operator works as a repressor that avoid transcription of the same ara operon
and the araC gene AraC protein is an activator in the presence of arabinose and
repressor in the absence of arabinose -With arabinose absent, the AraC protein
stays as
a homodimer. One AraC protein put together to the ara initiator and the other
protein now binds to a different regulatory site in DNA called the ara operator.
