The correct answer is C. Short tandem repeats are mostly different in unrelated peoples' DNA. Therefore, it is used to match the DNA of the people of the related family for identification of bodies, during a mass disaster like World Trade Centre. DNA from the nucleus is extracted in the process, and the STR containing regions are amplified and studied and can be matched with that of the relatives.
Answer:
The water potentials (Ψ) of the cell and its surroundings are the same.
Explanation:
When a cell is kept in hypotonic surroundings such as distilled water, the osmotic movement of water occurs towards the cell. The entry of water makes the cell swell up and it becomes turgid. Water potential is determined by solute and pressure potentials mainly. Here, the solute potential of the cell and the distilled water was different resulting in differences in their respective water potential values which in turn served as a driving force for endosmosis.
When the cell is fully turgid, the solute concentration of the cell and the surrounding distilled water become equal to each other. Under these conditions, the water potential of the cell and distilled water are the same.

Answer:
The correct answer is - stereotype threat.
Explanation:
