Answer: C - Chromosomes create genes
Explanation: took the test 100%
Answer:The ratio of the concentrations of
and
when the buffer has a pH of 7.02 is 0.69
Explanation:
The dissociation constant for formic acid =
Concentration of HA= 0.5 mM
Concentration of
= 0.1 mM
pH = 6.16
First we have to calculate the value of
.
Using Henderson Hesselbach equation :
Now put all the given values in this expression, we get:
To calculate the ratio of the concentrations of
and
when the buffer has a pH of 7.02.
Using Henderson Hesselbach equation :
Thus the ratio of the concentrations of
and
when the buffer has a pH of 7.02 is 0.69
Answer:
Gene expression is the process by which the information encoded in a gene is used to direct the assembly of a protein molecule. The cell reads the sequence of the gene in groups of three bases.
Explanation:
Answer;
The above statement is true
Explanation;
-Complement is a system of plasma proteins that can be activated directly by pathogens or indirectly by pathogen-bound antibody, leading to a cascade of reactions that occurs on the surface of pathogens and generates active components with various effector functions.
-C3b is the larger of two elements formed by the cleavage of complement component 3, and is considered an important part of the innate immune system. C3b is potent in opsonization: tagging pathogens, immune complexes (antigen-antibody), and apoptotic cells for phagocytosis.
