(02.04 HC)Water (H2O), carbon dioxide (CO2), and oxygen (O2) are all quite small molecules, yet they move across cell membranes differently. Both CO2 and O2 passively diffuse across the cell membrane directly while H2O moves across the cell membrane by facilitated diffusion. What can be concluded about these three molecules based on the way they react to the cell membrane?

(01.01 HC)Phoebe is taking samples from a lake to determine how the populations of aquatic life change during the summer. Each week, for a month, she takes samples from different areas of the lake. Over the course of a month, she finds the marine life listed in the chart below. What should Phoebe change about her methodology to better address her question?    Week 1Location 1 Week 2Location 2 Week 3Location 3 Week 4Location 4 Insects 13 20 18 15 Crawfish 8 15 20 22 Fish 3 11 13 12 Other 5 2 8 4

(01.01 MC)Farmers want to release a non-native insect in the fields that feeds on weeds. Before they do this, they consult a team of scientists and ask them to conduct a study that will determine the insects’ effects on the farm land. What can you infer about why farmers need the information from this study?
