A point mutation affects a single base and most commonly occurs when one base is substituted or replaced by another. Frameshift mutation results from the addition of one or more bases, known as an insertion, or the removal of one or more bases, known as a deletion.
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.

Explanation:
The fossil record shows a sequence from simple bacteria to more complicated organisms through time, it is very reliable because it is physical evidence and by studying fossils, scientists can learn how much (or how little) organisms have changed as life developed on Earth.
Answer:
The strengths of a focus group are:
-it gives the moderator more open ideas to work with.
-it has low cost compared to other data methods.
-it speeds up the result collection of the selected topic.
Weaknesses of focus group are:
*It takes effort to assemble the group members.
*Complex data analysis.
*No individual answers.
Explanation:
Focus groups usually involves a number of participants having an open discussion on a specific topic, set by a moderator, usually the person that comes up with the specific topic for focus. The function of a focus group is to collect data through group interactions on a selected topic.
