The attitude that is NOT important in science is <u>b. having a closed mind.</u>
<h3>What is a closed mind?</h3>
A closed mind refers to a person who is not willing to consider different ideas or opinions.
A closed mind cannot engage in scientific inquiries.
Scientific inquiry helps scientists to study the natural world in diverse ways before proposing explanations based on the evidence derived from their scientific activities.
Thus, important attitudes in science include:
- Curiosity
- Creativity
- Skepticism.
- Honesty
- Flexibility
- Persistence
- Open-mindedness
- Tolerance of uncertainty
- Acceptance of the provisional nature of scientific explanation.

Answer:
A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic. The pH scale is logarithmic and as a result, each whole pH value below 7 is ten times more acidic than the next higher value. For example, pH 4 is ten times more acidic than pH 5 and 100 times (10 times 10) more acidic than pH 6.
