A science teacher performs an experiment to measure the CO2 uptake of green algae chlorella under light conditions. He prepares a suspension of chlorella and places it in a growth experiment by turning off the lamp, creating dark conditions. Why is there a negative uptake of CO2 under dark conditions? |
Cellular respiration is taking place |
|
|
The presence of which structure indicates that cells are not photosynthetic bacteria? |
Chloroplast |
|
|

As part of a simulation of evolutionary process, a teacher drops 500 red and 500 green jelly beans on green grass. The red and green jelly beans represent individuals of the same species. Students represent predators and pick up as many jelly beans as possible and 30 seconds. Which prediction is most accurate? |
Green individuals are more likely to survive and reproduce. |

This table summarizes the information she gathered through observations and breeding experiments. Based on the most commonly accepted definition of a species, how many different species of a species of damselfishes is Dr. Romero raising, and which are they? |
2 species: Fish A and C are a single species ; Fish B is a separate species. |
