Answer:
The use of left arm is more compared to right hand
Explanation:
In the given question, the anthropologist when examines the left and right arm he found that the left arm is thicker than the right arm.
The more thickness of the left arm signifies that the person uses his left arm for the muscular work as the more use of hand increases the deposition of the calcium phosphate and sulfate in bones along with other material which increases the thickness for the bones and increases the strength.
Thus, The use of the left arm is more compared to the right hand is correct.
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.
