Because an antibody is "made" relative to the antigen, but kept at low levels when you are exposed the first time ("primary immune response"). The second time you're exposed to the same antigen, memory cells recognize it and the body produces a high level of antibodies, and the level of antibodies usually remains higher for a longer time ("secondary immune response"). This is your basic immune response (primary and secondary).
This explains exactly why vaccines are effective to extremely effective.
Explanation:
The enzymatic digestion of starch by amylase can be performed in the laboratory by several ways. But below there is an example of it
In order to have the best protein performance we have to set the temperature of the reaction to 37 celsius degrees.
- Prepare a starch solution and spread into tubes
- Prepare an amylase solution and spread into tubes
- Adjust the pH to the optimum range with buffers, that is about 6.7 to 7.
- Adjust the temperature of the tubes reaction to 37 celsius degrees.
The wrong temperature and the pH can unfold the enzymes and make the binding site inefficient.
- Pipette the starch solution in the tubes with enzymes.
By the final step the glucose will be produced by the enzymatic digestion of amylase.
It's attached the scheme of the hydrolyzation of a starch strain
Chromatin is a simpler for of a chromosome. For example, in mitosis (somatic cells dividing) chromatin is in the nucleus, however when it condenses, it forms chromosomes.
Trigone of the urinary bladder is made from three orifices, two <span>ureteric orifice and one urethra orifice.
Ureteric orifice is made by ureter from the left and right kidney. It's the place where urine enters the bladder.
Urethra orifice is connected to urethra and it's where the urine comes out of the bladder.</span>
