Ans.
Diffusion, osmosis, and active transport are mechanism of cellular transport that involves movement of molecules through plasma membrane. Diffusion shows movement of small, hydrophobic particles without the help of protein molecules through cell membrane along the concentration gradient.
Osmosis involves movement of water molecules against concentration gradient (from an area of high solvent concentration to an area of low solvent concentration) through cell membrane.
Active transport shows movement of particles, against the concentration gradient, means from a region of higher to lower concentration of molecules through cell membrane. It involves transport through membrane proteins.
Thus, the part of cell, which is affected by the movement of molecules through osmosis, diffusion, and active transport is cell membrane or plasma membrane.

Answer:
2. Alec Jeffreys
Explanation:
'DNA fingerprinting' or DNA typing (profiling) as it is now known, was first described in 1985 by an English geneticist named Alec Jeffreys. Dr. Jeffreys found that certain regions of DNA contained DNA sequences that were repeated over and over again next to each other.
