Answer:
I think true statement is A.
Answer:
Plasmolysis
Explanation:
In the image 1 the cell is having sufficient quantity of water leading to a turgid cell.
The image 1 plant cell is in a dilute solution in which water enters into cell from external medium.
The image 2 plant cell is exposed to a solution which is high concentrated solution.
Due to this high concentrated solution the water present in the cell is send out by exosmosis.
Due to loss of water from plant cells the protoplasm in plant cell shrinks in which cell membrane gets separated from cell wall.
This shrinkage of protoplasm by loss of water is called plasmolysis.
The answer is B, because layers mix better at the poles.
Answer:
siRNA.
Explanation:
The RNA interference may be defined as the evolutionary conserved mechanism that helps in the gene regulation by the silencing of the small RNA molecules. Two main types are siRNA and miRNA.
The siRNA (small interference RNA) is involved in the protection of the cell by destroying the exogenous ds DNA of the cell. The DICER enzyme plays an important role in the processing of the small interference RNA and the guide strand of RNA is involved in the gene silencing.
Thus, the answer is option (a).
