Answer:

The correct answer is - purine nitrogenous base (adenine).

Explanation:

The base given in the diagram in the image has two rings attach with the pentose sugar which is attached to the phosphate, which means it is the diagram of nucleotide. In this nucleotide base can be either purine or pyrimidine.

Pyrimidines have a single ring structure, whereas purines have 2 ring structures. Adenine and guanine are purines with two ring structures whereas cytosine and thymine are pyrimidines as they have one ring structure. Adenine contains an amine group on C6, and a double bond between N1 and C6.

beks73 [17]

Answer:

They will collapse and shut off the stomatal pore

Explanation:

The guard cells are regulated by the presence of water. When water is present, they become turgid and open up the stomatal pore and when water is inadequate, they become flaccid, collapse and close up the stomatal pore as a result.

<em>If the leaf is left under the microscope for too long, there will be loss of water by evapotranspiration and the guard cell will become flaccid and collapse as a result and the stomatal pore will become closed.</em>
