Answer:
true
Explanation:
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. The same holds true for pH values above 7, each of which is ten times more alkaline (another way to say basic) than the next lower whole value. For example, pH 10 is ten times more alkaline than pH 9 and 100 times (10 times 10) more alkaline than pH 8.
Answer:
Beaker A= Isotonic
Beaker B = Hypotonic
Beaker C= Hypertonic
Explanation:
ISO means the same on each side.
Hypo means less.
Hyper means more.
Case studies do not allow for replication. So, the correct option is (b).
Case studies are investigations that compile in-depth information about a person or group. They employ a wide range of research techniques, including observations, interviews, case studies, and personality tests, to collect the data. They can frequently collect both qualitative and quantitative data thanks to this. Research can be cross-sectional or longitudinal, which lasts for a long time.
It enables a researcher to thoroughly explore a subject. Case studies are unreliable because they cannot be duplicated and hence cannot be reliability tested. Any data acquired cannot be used to make generalisations because the outcomes are specific to the time, event, setting, and individual.
