Answer:A.) True
Explanation:
E.Coli would be a good model organism to study how the cell membrane controls movement of substances in and out of cells because it a eubacteria .Eubacteria characteristics include the ability to allow the movement of molecules across its membrane once a proton gradient is established , The membrane also has permeability enhancing properties that allow for the easy movement of substances.
Answer:

Explanation:
The pH scale stands for the power or potential of hydrogen. It measures how acidic or basic a solution based on the concentration of hydrogen ions and a scale from 1 to 14.
This scale is unique because it is logarithmic. So, every time the pH changes by 1 on the scale, the actual concentration of the solution increases or decreases by a tenfold.
So, a solution with a pH of 7 is ten times more acidic than a solution with a pH of 8. This can be translated to:

The black coffee has a pH of 5 and the hand soap has a pH of 10. We want to find how many times more acidic coffee is, so we subtract 5 from 10 and get 5. The difference in pH is 5.

Coffee is <u>10⁵ or 100,000 times more acidic than hand soap.</u>
Answer:
In ancient Egypt, women were given many of the same rights as men.
Explanation:
The women in ancient Egypt were in no way seen as the lowest social class, so this statement is not correct.
The women were allowed by law to do pretty much everything as the men, so their status was not dependent on their husbands, so it is not a correct statement.
The women were equal in front of law in ancient Egypt, as well as being able to do the same things as men, so this statement is correct.
Women did not have the same status as their fathers, so this is not a correct statement.
