Wylie Biology 1406 Review

Front

What happens to the pH of a solution when the hydroxide ion concentration increases?

Back

The solution becomes more basic.

Front

What is the dilution formula used to calculate the concentration and volume of solutions?

Back

C1V1 = C2V2

Front

Which laboratory instrument is the most accurate for measuring liquid volume: micropipette, graduated cylinder, or beaker?

Back

Micropipette is the most accurate.

Front

How do you determine protein concentration using a standard curve?

Back

By measuring the absorbance and correlating it to the concentration on the curve.

Front

What is the independent variable in an experiment involving Daphnia and drug administration?

Back

The drug administered (ethanol or caffeine).

Front

Define an acid in terms of its ion concentration in a solution.

Back

An acid increases the concentration of hydrogen ions (H+) in a solution.

Front

Define a base in terms of its ion concentration in a solution.

Back

A base increases the concentration of hydroxide ions (OH-) in a solution.

Front

What is the purpose of a graduated cylinder in a laboratory setting?

Back

To measure liquid volumes accurately.

Front

What is the significance of using a micropipette in biological experiments?

Back

It allows for precise measurement and transfer of small volumes of liquid.

Front

How do you prepare a 5% solution from a 10% stock solution?

Back

Use the dilution formula: C1V1 = C2V2 to find the required volumes.
