They receive blood from internal and external veins of the brain,and receive cerebrospinal fluid (CSF) from the subarachnoid space via arachnoid granulations, and mainly empty in the internal jugular vein</span>
The answer is all of the above
Answer:
1.5 micro liter.
Explanation:
Antibodies may be defined as the substance hat are produced by the immune cells of the body against the particular antigen. The antibodies concentration is helpful to determine the infection stages.
The amount of primary antibody can be calculated by teh following formula:
N1V1 = N2V2
Here, N1 = amount of primary antibody = 1, N2 is dilution factor 1/3333 and V2 is 5 ml = 5000 micro liter.
Then V1 can be find as follows;
V1 × 1 = 1/3333 x 5000
V1 = 1.5 micro liter.
Thus, the answer is 1.5 micro liter.
