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.
Answer:
Mutation.
Explanation:
All adaptations begin as a genetic mutation because these adaptations passed from one generation to another generation through genes of that organisms. Organisms that are adapted to their environments and survive more better, it will produce more offspring in which that genetic characteristics are transmitted from the parents so we can say that genetic mutation is responsible for adaptations.
Cellulose is found in the cell walls of plant cells. It is permable so any substance disolveabls in water can pass through so it dose not act as a barrier. It gives the cell its strength and support. As water moves in to the cell by osmosis it stops the cell from bursting.
