Papessa [141]
<span>The answer to this question would be: tissues; decrease

Oxygen is delivered to the tissue by the heart. It will be unloaded in the tissue, causing the oxygen level in the blood to be decreased. After that, the blood also picks up the carbon dioxide so its level will be increased.

The pH scale measures the acidity of a substance. It is a negative logarithmic scale. A pH of 3 has a hydrogen ion concentration
Hitman42 [59]

Answer:

The correct answer is: a pH 2 solution has a <u>10000 times</u> greater hydrogen ion concentration than a pH 6 solution.

Explanation:

The pH scale is a measurement used to describe the acidity of a solution, and this acidity is given by the concentration of H+ (hydrogen ion) in said substance. A solution with a greater concentration of H+, is more acid than a solution with a smaller concentration of H+ and, therefore, has a lower pH. Given that the pH scale is a negative logarithmic scale, a solution with a pH of 3 has a ten times greater H+ concentration than a solution with a pH of 4.

A pH 2 solution has 10 times more H+ ion concentration than a pH 3 solution, 100 times more H+ ion concentration than a pH 4 solution, 1000 times more H+ ion concentration than a pH 5 solution, and 10000 times more H+ ion concentration than a pH 6 solution.

in a population of sexually reproducing bacteria how can we select for the resistant ones by only taking antibiotics for 2 days
VladimirAG [237]

We can select the resistant microbes that were survived on the second day of antibiotic application.

<h3>How can we select for the resistant ones?</h3>

We can select for the resistant ones by only taking antibiotics for 2 days instead of the full 10 days that the drugs were prescribed in order to see the microorganism that survived on the second day. Bacteria get resistance when they are exposed to similar type of chemicals for a long time. Some of bacteria mutate and make defenses against the chemical which leads to survival of that organism.

So we can conclude that We can select the resistant microbes that were survived on the second day of antibiotic application.
