Answer:
<em>C: After 1 hour, the pH of the solution in the PEPCID AC beaker was 9.2 and the pH of the solution in the Alka-Seltzer beaker was 8.3</em>
Explanation:
The degree of acidity or alkalinity/basicity of a substance is its pH. The value of pH ranges from 1 to 14 with the former being extreme acidity and the latter being extreme alkalinity while pH 7 is considered neutral.
Hence, any pH below 7 is considered acidic and above 7 is considered alkaline.
Reactions involving equal volumes of an acid and a base can end in acidic, alkaline or neutral pH depending on the strength of the acid/base involved;
- Equal volumes of strong acid with strong base will result in neutral pH
- Equal volumes of weak acid with strong base will result in alkaline pH
- Equal volume of strong acid with weak base will result in acidic pH
If substance A and B reacts with equal volume of the same acid under the same condition and the end result of A is a solution with pH of 9.2 and that of B is a pH of 8.3, it simply means substance A is a stronger base than substance B.
<em>Hence, the only outcome that supports the hypothesis that a tablet of PEPCID AC can neutralize more stomach acid than a tablet of Alka-Seltzer is that the pH of the solution in the PEPCID AC beaker was 9.2 and the pH of the solution in the Alka-Seltzer beaker was 8.3 after being subjected to the same condition.</em>
If an indigestion is due to excess stomach acid, the only way to reduce the acidity is to consume a substance that will decrease the degree of acidity in the stomach. This means that the patient will need to consume something that is alkaline in order to increase the pH.

Answer:
The given blank can be filled with location of gene expression.
Explanation:
A regulatory sequence refers to a section of a molecule of nucleic acid that possesses the tendency of declining or upsurging the expression of particular genes within an organism. The regulation of gene expression is an important characteristic of all living species and viruses.
In the given case, it is essential to use the regulatory sequence of a milk gene when developing a recombinant gene as a regulatory sequence monitors the location of gene expression.
