I am not totally sure but I think it’s B
Water molecules are polar. This means that one end of the molecule is positively charged, while the other is negatively charged. Opposite charges attract. Water molecules on the faucet that are eventually pulled away from the others by gravity will themselves pull together and form round drops because the charged portions of molecule attract the oppositely charged portions of another.
Proteins are diverse because of the various combinations of amino acids there are.
Answer:
The answer is: The lac operon transcription would be reduced.
Explanation:
The lac operon is the machinery that bacteria uses to break down lactose to use it as an energy source when there is no glucose around. The catabolite activator protein (CAP) senses glucose via a molecule called cAMP. If the levels of glucose are high then no cAMP is produced and therefore no cAMP would be able to bind CAP. That would leave CAP inactive and the transcription would occur but at low levels. The same would happen if CAP protein would have a mutation that would leave it inactive.
