What is a quantitative observation

A quantitative observation is something that measures a quantity (number), such as the weight of length of an object. Quantitative observations have numbers, such as 3 pounds or 5 meters.

The opposite is a qualitative observation, such as something is round or that it is blue. There are no numbers involved, the thing is either round or it's not.

What do bacteria have in common with the cells of other living organisms

They have ribosomes.They contain cytoplasm.

To help you conclude that no uncontrolled factors significantly influenced your results.

To help you determine that your experimental results are valid

To help control for factors that aren't being tested but might affect results
