The extracellular glucose inhibit transcription of the lac operon (D) by reducing the levels of intracellular cAMP.
Lac operon is the assembly of various genes that are involved in the uptake and metabolism of lactose of E. coli or any other bacteria. It consists of a regulator gene, promoter gene, operator and structural gene. Structural genes are three: z, y and a. Each codes for a different enzyme.
cAMP is the cyclic Adenosine Monophosphate. It is produced by the bacteria when there are low levels of glucose in it. Hence it is also named as hunger signals. Therefore, cAMP is responsible for activating the operon to produce lactose.

Answer:
Eating a diet of low levels of protein could leave you to development a condition called edema, which causes swelling in your legs and feet from the buildup of fluids. Protein plays an essential role in maintaining salt and water inside your blood vessels and ensuring fluid does it make its way into the tissues. Hajima can cause stiffness, difficulty walking, increasingly painful swelling.

High littoral zone has greatest abundance of marine organisms.
<h3>What is High littoral zone?</h3>
The intertidal zone, also known as the "littoral zone," refers to the seashore that is covered during high tide and exposed during low tide, revealing a unique biome that survives under such fluctuating conditions.
<h3>Where are most marine organisms found?</h3>
The majority of ocean life can be found in coastal habitats on the continental shelf, despite the fact that this area accounts for only 7% of total ocean area. The majority of open ocean habitats are found in the deep ocean beyond the continental shelf. Species that live in the oceans and on the coasts can help to create new habitats.
