The answer is <span>Take consistent amounts of saliva samples from a number of people who have not eaten in 8 hours and measure the quantity of amylase in each sample.
First, the researcher needs to know the quantity of amylase in the <u>same</u> amount of saliva. Thus the amount must be consistent and not varying.
Next, people must not eat in 8 hours, so they are all in the same condition at the moment of collecting saliva. If some eat immediately before the sample collecting while some eat 8 hours before, the content of their saliva will be different.
For the correct results, all conditions must be the same.</span>

The statement that is true about a buffer is that it reduces the amount of H+ in an acidic solution (option B).
<h3>What is a buffer solution?</h3>
Buffer is a solution that is used to stabilize the pH (excess acidity or alkalinity) of a liquid.
Buffers operate by neutralizing any added acid (H+ ions) or base (OH- ions) to maintain the moderate pH, making them a weaker acid or base.
Therefore, it can be said that the statement that is true about a buffer is that it reduces the amount of H+ in an acidic solution.
