The correct answer is option (B) lemon juice.
pH refers to the logarithmic scale used to indicate the acidity or basicity of an aqueous solution. It is the negative of the base 10 logarithm of the activity of the hydrogen ion. Solutions with a pH less that 7 are considered acidic and the solutions with a pH greater that 7 are considered to be basic. A pH of 7 is neither an acid nor a base and is considered neutral.
An acid has a high concentration of hydrogen ions (H+) and a base has a low concentration of hydrogen ions. Higher the hydrogen ion concentration, pH is acidic. Among the given substances, lemon juice has a pH of 2, urine has a pH of 6, tomato juice has a pH of 4 and black coffee has a pH of 5. Since lemon juice has a pH of 2, it has the lowest –OH ion concentration.
The question is incomplete as it does not have the options which are:
A. novelty
B. creativity
C. consensus
Answer:
A. novelty
Explanation:
Novelty refers to a qualitative identity that is used to represent the new ideal things or some fresh and refreshing ideas.
In the given question, the person who was presenting about the idea of How DNA works in genetics? failed to present something new about the DNA and just presented what was already known to the audience.
Since the presenter failed to express the new ideas in his presentation about the DNA that is no novel ideas were presented therefore the audience started to leave the presentation.
Thus, Option-A is correct.
Photosynthesis turns carbon dioxide and water into oxygen. The chemical change happends. It is an Endothermic reaction cause energy needs to be in and order for photosynthesis to happen. Then then the plant puts the food away for later lime in the winter or when it is dry
