Answer:
<em>The correct option is lac operon will function normally.</em>
Explanation:
The promoter region can be described as a region due to which transcription begins for a certain gene. Promoters can be present near to the gene for which they initiate transcription or they might be present several sequences away upstream.
The promoter region will still be able to initiate transcription several base pairs away hence the lac operon will function normally. The repressor will also detect the promoter and function normally.

Nutrients cross the membrane wall with the help of protein channels.
Answer and Explanation:
In homeostatic control processes any deviation from the norm sets into motion the appropriate corrective mechanisms which restore the norm. This rectification occurs through negative feedback. When you go outside wearing a sweater on a hot day, the body sends messages to the CNS and the following occurs:
- The superficial blood vessels vasodilate so that more blood flows near the surface. This encourages heat loss.
- Sweating and panting. Sweat secreted by the sweat glands evaporate from the surface of the body as it absorbs latent heat.
- The metabolic rate falls so that the body generates less heat. You also become less active
- Behavioural response by seeking cooler areas, cold drinks or removal of the sweater.
