Slide 48 is missing the word Dioxide
Cara - I understand where you are coming from. That said, the slide is referring to the carbon atom, not the carbon dioxide molecule that organisms exhale. E.g., the 4 biomacromolecules of life (carbohydrates, lipids/fats, nucleic acids, and proteins) are all carbon derivatives, not CO2 derivatives.
Review the matter of Plants (slide 49) Typo
Slide 63 Thrings typo instead of things
Slide 65 the picture will not move far enough to see what is underneath
Slide 67 absorbing is spelled wrong
Cara - thank you for the feedback - we corrected these errors and also double checked the whole presentation. For slide 65, you click on the picture and it fades out. - Melissa
