Answer: Because the cell will expand and burst
When a cell is frozen, that means the cell temperature is going to be lowered extremely. Ice has more volume than water which is why it floating inside water. That's why if you put water in a plastic container then freeze it, the container will get pressured and swollen. If the container is not elastic enough(metal, glass), it will burst.
Same like that, the cell that got frozen can be burst too.
Answer:Isotonic: The solutions being compared have equal concentration of solutes. Hypertonic: The solution with the higher concentration of solutes. Hypotonic: The solution with the lower concentration of solutes.
Explanation:
False, that is one thing many people were always doing, back then.
The study 'Immunogenicity and safety of the adjuvanted recombinant zoster vaccine' aims to identify the functions of the pneumococcal polysaccharide vaccine in adults.
<h3>What is Immunogenicity?</h3>
Immunogenicity can be defined as the properties that a given macromolecule or vaccine has to trigger a concomitant immune response.
Moreover, adjuvanted recombinant vaccines are based on specific compounds that boost the immune response, and these vaccines are generated by DNA recombinant techniques.
In conclusion, the study 'Immunogenicity and safety of the adjuvanted recombinant zoster vaccine' is a scientific publication that aims to identify the functions of the pneumococcal polysaccharide vaccine in adults.

Answer:
B. Electrophoresis separates molecules based on charge differences, thereby making it possible to separate molecules that are similar in size, shape, and density.
Explanation:
Chromatography is a process that is used for the separation of complex mixtures of molecules by many repeated partitioning between a flowing (mobile) phase and a stationary phase. The process exploits the properties of the molecules such as charge, size, binding affinity, etc.
However, gel electrophoresis is the technique that separates the molecules based on their charge or mass. It can separate a mixture of molecules with a similar charge based on their mass. Likewise, if all the molecules of a mixture have the same mass but differ in charge, gel electrophoresis can be used to separate them based on their different charges.
For example, a mixture of proteins is allowed to run through the gel of cross-linked polymer polyacrylamide under electrical potential towards the positive or negative electrode. The polyacrylamide gel serves as a sieve and allows the proteins to migrate in proportion to the charge to mass ratio. If all the proteins are of the same mass, gel electrophoresis would separate them based on their charge.
