If the size of the molecules is related to the rate of diffusion as they pass through a membrane, then smaller molecules will flow through at a higher rate.
What is hypothesis

To test the lake for contamination we took water samples from different regions of the lake and believe that it contains contamination.
What is inference
300
What are the steps to the scientific method?
1. Asking a question
2. Forming a hypothesis
3. Setting up a controlled experiment
4. Recording and Analyzing Results
5. Drawing a Conclusion
300
The combination of chemical reactions through which an organism builds up or breaks down materials as it carries out its life processes.
What is metabolism
300
This tool produces magnified images by focusing visible light rays.
What is light microscopes
300
What do numbers 0-6 represent on the pH scale?
What do numbers 8-14 represent on the pH scale?
What does the number 7 represent on the pH scale?

The maggot arose from the meat, the mice from the grain, and the beetle from the dung. These are examples of life arising from nonliving things.
What is spontaneous generation.
400
What purpose did the curved neck of the flask serve in Pasteur's test of spontaneous generation.
It proved that air is not the "life force" needed to produce new life. He disproved spontaneous generation and proved once and for all that living things come from other living things.
400
Involves internal feedback mechanisms that work in much the same way as a thermostat.
What is homeostasis
400
When do you use an electron microscope compared to a light microscope?
Light microscopes allow you to study live specimens. Electron microscopes revel a wealth of detailed information inside the cell (TEM) and the surface (SEM)
400
What are the parts of a solution and which dissolves in which?
Solute and solvent. Solute dissolves in solvent
500
What is a controlled experiment? What are the manipulated and responding variables in Redi's experiment?
Controlled experiment: hypothesis that should be tested in an experiment in which only one variable is changed at a time. All other variables should be kept unchanged, or controlled.
500
How do scientists today usually communicate their results and conclusions?
What is Scientific journals online
500
What are the levels of organization in which living things are studied?
Biosphere, Ecosystem, Community, Population, Organism, Groups of cells, Cells, Molecules.
500
What is cell fraternization?
To separate the different cell parts.

What is the difference between cohesion and adhesion and give examples of each.
What is the difference between mixtures, solutions, and suspensions and give examples for each
Cohesion: attraction of molecules of the same substance.
Adhesion: attraction of molecules of difference substances.
mixtures: physically together but not chemically combined; salt and pepper.
Solution: components evenly dispersed throughout solution
suspensions: materials that do not dissolve in water and separate.
