Although the Venn diagram is not attached, I was able to find it and the characteristics in A are:
Chlorophyll in chloroplasts
Autotrophic
Cell walls of cellulose
Large central vacuole
The characteristics under B are:
Heterotrophic
Cell walls made of chitin
Sometimes multinucleate
Hyphae
The mutual characteristics are:
Organelles
Cytoplasm
DNA in nucleus
Cell membrane
Therefore, A represents plants and B represents fungi.
Answer:
13% cytosine
37% thymine
Explanation:
Chargaff's rule states that the DNA always has a 1:1 ratio of purine bases (the cytosine and thymine to pyrimidine bases (guanine and adenine).
If there is 13% guanine, then there must also be 13% of cytosine (since G pairs with C)
The total of guanines and cytosines is 26%, meaning the total of A + T is 100% - 26% = 74%. That means there are 74/2 = 37% of thymine.
The pepsin would become denatured and inactivated as its optimum pH is acidic, because acidic pH is found in the stomach.
