Reproductive isolation is the process to keep away two various species from mating with each other. An example is two fish species from the sticklebacks family. One species lives in fresh water all year while the other one lives in the sea during winter and goes to rivers to produce their offspring every spring and summer. This is specifically called temporal isolation.
Answer:
Agarose gel electrophoresis is the most suitable method for this analysis.
Explanation:
SDS-PAGE, sodium dodecyl sulfate polyacrylamide gel electrophoresis, is a procedure used for visualizing and separating proteins according to their molecular weight. The use of sodium dodecyl sulfate and polyacrylamide gel eliminates most of the influence of the tertiary structure and charge, and proteins are separated solely based on polypeptide chain length. So, if the student suspects that the protein sample is conformed of 4 subunits similar in molecular weight, SDS PAGE will likely not separate them.
On the other hand, an agarose gel electrophoresis can separate proteins based on their size AND charge, so, if you suspect that the proteins are not identical but similar in size, the charge factor can be important to separate them in an experiment.
A and C is the answer for your question and yes I did some calculations
The process that occurs in a cell when there is not enough oxygen
is called fermentation. Fermentation occurs through the process of Anaerobic Respiration,
where instead of using oxygen, organic and inorganic molecules are used as
final electron acceptors. The by-product of this process is usually alcohol,
ethanol, or acetic acids.
<span>
Fermentation is commonly used in lactic acid (in muscles) and alcohol (beers,
whiskey) fermentation where the by-product is ethanol. Yeasts are a common
organism that uses this process, where it convert sugars into alcohols or
acetic acids.</span>
