Answer:

An allergic reaction

Explanation:

An allergic reaction occurs when our immune system misinterprets a harmless substance into a harmful antigen and initiate an over-expressed immune response against it. Some of these allergic substances are pollen, molds, insect stings, etc.

These allergens trigger the production of IgE antibodies in the body which interact with different cell and initiate the release of chemicals like histamine that cause symptoms of allergic reaction.

It can affect the nose, skin, lung, stomach lining, etc. Therefore the correct answer is an allergic reaction.

ivanzaharov [21]

Answer:

t=v/a

Explanation:

To solve for Time

Since acceleration is change in velocity/time

a=v/t

Cross multiply

a×t=v

at=v

Divide both side by a since we want to find Time

at/a=v/a

t= v/a

1) I have to find the total yield of protein (rGFP) given estimated purity (in %) and amount of proteins. I have the purity of t
Mars2501 [29]

Answer:

Please look at the explanation section.

Explanation:

1) To calculate the yield of a protein in the purification step, the amount of protein produced must be divided by the amount of protein produced in the first step. The expression is as follows:

%protein yield = (Amount of protein/Amount of protein produced in the first step) * 100

If you have the purity percentage and the amount of protein produced, this formula could be used:

%protein yield = (Protein amount * Purity Percentage)/100

2) If this process begins with a cell culture and ends with the purification of Ni+2NTA. One method of increasing performance is to decrease the number of steps in the purification process. Because unfortunately, at each step of the purification of a protein leads to the loss of them.
