A vaccine contains half killed or weakened pathogen such as a virus or bacterium, which causes a specific disease. A vaccine can be administered orally or through an injection in a healthy human. The function of the vaccine is to train the immune system by detecting the pathogen and kill them. After vaccination the cells (B lymphocytes) of the immune detects the antigens in the vaccine. The B lymphocytes make antibodies against the antigen and eliminate antigens. These antibodies  remained in the body and in case of real infection, they protect our body from pathogen.

Which part of the cell is affected by the movement of molecules through diffusion, osmosis and active transport?
kolezko [41]

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.

In a scientific investigation of lakes, the depth of a lake is most likely to be measured in
sergey [27]

Answer:

D

Explanation:

Units of weight and volume won't be large enough to be meaningful. so liters and grams are too small. Find out the weight of a cubic meter of water and then estimate how many cubic meters there might be in a lake. Millions would probably be too small.

Miles are too big. Most lakes do not go to a depth of 1 mile, but you on on the right track. Distance is what you want.

Meters are the answer.
