Explanation:
The missing options of this question are:
A) The emergence of a larger middle class in the North
B) A decline in economic inequality in urban areas
C) An increased demand for agricultural workers in the Midwest
D) The improvement of working conditions in factories
The correct answer is "The emergence of a larger middle class in the North"
The period of 1800 to 1848 is characterized by being of economical growth due to the rise in manufacturing technology.

Explanation:
When there are low oxygen levels in blood, the blood pH tends to lower. This is because there is an increased level of carbon dioxide in the blood that is converted to carbonic acid by carbonic anhydrase. When carbon acid dissociates, into H⁺ and HCO₃⁻ . The H⁺ influences the increase in acidity of the blood. The kidneys will excrete most of the H⁺ and retain most of the HCO₃⁻ to help maintain the right blood pH. However, most of blood pH homeostasis is maintained largely by the lungs.

<u>Answer:</u>
The series dilution method is the step wise dilution technique where the dilution factors remain constant in each step.
The advantages of using the series of dilution method over simple dilution are stated below:
<em>a) Aids in reduction of a dense culture of cells to a more usable concentration.</em>
<em>b) In every step of dilution the specific amount of bacteria is removed. </em>
<em>c) Helps in the estimation of concentration of an unknown sample.</em>
<em>This sums up the advantage of using the series dilution technique.</em>
The disorder can occur anytime
