Answer:
B.
Explanation:
A is wrong because pyruvate would enter the Krebs cycle under aerobic condition (when oxygen is present). Hence the name aerobic cellular respiration
C. I do not really too much about fructose or the concentration of oxygen, but I can assure that this answer choice is not correct.
D is wrong because NADH would be converted from NADP+. Either with oxidation or reduction, and this helps to keep this process going.
B is correct because fermentation is another word for anaerobic cellular respiration. The process takes place with the absence of oxygen. It either goes through Alcoholic or lactic acid fermentation.
I hope this helps!
The mother's genotype can be either 
or 
.
For X-linked recessive traits, males (XY) can either be affected or free from the disorder, they cannot be carriers. Females (XX), on the other hand, can be affected, unaffected, or be carriers.
The circled male child is free from the disorder (
) while the females are carriers ().
The male inherited the healthy allele, 
, from the mother.
The female children inherit the affected allele from their father (who is affected for the disorder) and the other healthy allele from their mother.
This means that the mother cannot be affected for the disease. As it is, the pedigree points that all the children got their healthy alleles from their mother. This does not mean the mother has two healthy alleles though.
Thus, the possible genotype of the mother are and .

Trypsin is a serine protease found in digestive system of vertebrates. they are produced in the pancreas.it catalyzes the hydrolysis of peptide bonda, breaking down into smaller peptides
in tissue culture, trypsin is used to re suspend cells adherent to the cell culture dish wall.
Erepsin is a protein found in intestinal juices but can also be found in many other cells.
