1. Six-one drop samples in a Paramecium sp. population had the following numbers of organisms: 4, 6, 5, 3, 6 and 6. If 20 drops represent 1 mL of solution, and the volume of the solution is 40 mL, calculate the size of the population.

2. White spruce may compete with lodgepole pine for light and living space. Eventually, white spruce many take over.

The jar is 40 mL.

According to the question, 20 drops represents 1 mL.

20 drop : 1 mL
1 drop : x mL

Therefore, x = 0.05 mL

So, every drop is 0.05 mL, and in every 0.05 mL, you will find 4, 6, 5, 3, 6 and 6.
