Two students are studying what makes ice melt fastest. They want to conduct an investigation. During which of these steps in their investigation will they measure the ice? The choices are:
A) Showing graphs
B) Making a conclusion
C) Developing a hypothesis
D) Collecting data

(EDIT, the last set of answers i had was incorrect, and was for a diff. question, sorry!)

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

a- multicellular

b-eukaryotic

c-no cell wall

d-heterotrophic

e-autotrophic

c is the answer to this question. altitude affects the weather because air molecules evaporate.
