Assume you inoculated 100 cells, with a generation time of 20 minutes, into 100 ml of nutrient broth. You then inoculated 100 cells of the same species into 200 ml of nutrient broth. After incubation for 4 hours, you can reasonably expect to have .
A) the same number of cells in both. B) more cells in the 100 ml. C) more cells in the 200 ml. D) The answer cannot be determined based on the information provided.

The correct answer is option A) "the same number of cells in both".

Explanation:

The volume of nutrient broth in two different cell cultures is not a variable that would affect the number of cells that are produced. The only way that this could be a factor would be if the cell number is high enough that the nutrients could be depleted. However, in this case where 100 cells with a generation time of 20 minutes are inoculated and the incubation time was of only 4 hours, the volume of nutrient broth is not a factor that would affect them.

the answer is d. chordata

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
