You eat an apple for breakfast, which contains 1.2x1022 molecules of glucose. If your cells take all of that glucose to the mitochondria for cellular respiration, how many water molecules will be created?
7.2x1022 molecules of water
1.2x6=7.2Organisms that carry out photosynthesis are also known as...
Producers
If you had to create a new species and it had to survive for the next 1000 years, would you make it an asexually-reproducing organism or sexually-reproducing? Explain.

We did a reading and simulation on the evolution of peppered moths. Explain what happened to the dark and light moths in each of the different forests. Explain how this is an example of natural selection.
In the dark forests, dark moths survived because they could camouflage easier.
This is natural selection because over time, the light moths were eaten in the dark forest, so the light moths could not survive and reproduce, and the dark moths could, so eventually the population was mostly dark moths.
