Sorry for not answering your question but I just wanted to say you have amazing handwriting :)
Answer:
Proten W
Explanation:
SDS-PAGE gel is a method used for the separation of proteins in which proteins are separated based on their length (smaller proteins move faster through the gel, due to less resistance).
When treated with proteolytic enzymes, proteins are cut and become short fragment. This means that the fragments formed after the use of proteolytic enzymes, will move faster and thus, migrate a longer distance. Proteolytic enzymes in Set 2 cells will act only on plasma membrane proteins (because they cannot penetrate), while in Set 2 they will act on both, plasma membrane and interior proteins. Control group will have only the large fragments (not treated with enzyme).
Protein W travels the same distance on a gel of proteins from Set 1 and Set 2, but different than control group. It means that the proteolytic enzyme worked the same on Set 1 and Set 2.
I am pretty sure the answer is increase and increase. Because enzymes are affected by changes in pH. The most favorable pH value - the point where the enzyme is most active - is known as the optimum pH. Extremely high or low pH values generally result in complete loss of activity for most enzymes.
The answer is A, true.
Fungal cells have cell walls which are made out of chitin, unlike plant cells, their cell walls are made up of cellulose.
Other reasons that why fungi are not classified as plants include that because they have no chloroplast, instead they feed on dead organic matters. Another reason is that they store carbohydrates in form of glycogen, instead of plants which store carbohydrates as starch instead.
Carbon dioxide moves out of the tissues (cells) into the bloodstream to be exhaled in internal respiration.
