A memory B cell is kinda of how it sounds it has a memory of what your body has fought before such as a virus and can stimulate a response quicker then the first time you encountered it.
If you lack memory B cells your body doesn't built up the same immune response when you come into contact with the virus again.
"Vaccination would prevent further disease" Incorrect, a vaccine lets you build up memory cells to combat the disease if you lack them you cannot build up a defense.
"Vaccination would not prevent further disease" Correct, a vaccine can be a dead version of a virus or parts of a virus that shows your body what to respond to quickly in the future. If you body cannot make memory b cells it wouldn't help to use a vaccine. Your body wouldn't keep a memory of it being bad.
"You would not produce antibodies" Even if your body does not remember a particular virus it does produce antibodies to combat it just not as quick or efficiantly as something it has come into contact with before and produced memory cells.
"You would over produce histamine" Incorrect, different process for that histamine.
Answer:
% of wolves have normal fur.
Explanation:
Given , the allele for white fur is recessive and the allele for normal fur is dominant
Let "N" represents the allele for normal fur and "n" represents the fur for white fur.
As per Hardy Weinberg's principle, the frequency for dominant allele is represented by "p"
Given ,
Then frequency for dominant genotype will be "
"
So, Frequency for wolves with normal fur is
Percentage of the wolves with normal fur is
%

Answer:
Pancreatic juice, NaHCO₃.
Explanation:
The buffers are the chemical solution which neutralizes the acidic effect and the human body also produces the biological buffers which help maintain the pH.
The pancreatic juice secreted by the pancreas gets drained into the duodenum of the small intestine and neutralizes the effect of the acidic content in the stomach bolus. The pancreatic juice contains the sodium bicarbonate which neutralises the effect of the HCl.
Thus, Pancreatic juice, NaHCO₃ is the correct answer.
