What makes benign and malignant tumors different?
Benign tumors remain in the same tissue they began in. Malignant tumors have metastasized into other tissues in the body.

Example:
Mushroom (decomposer)
Fox (tertiary consumer)
Mouse (secondary consumer)

200
Define the "field of view" in a microscope.
The diameter of the area (typically a circle) that can be seen through the microscope in a given lens magnification.
200
When do the three check points in the cell cycle occur?
End of G1, end of G2, and middle of M phase.
200
Differentiate between an INDEPENDENT and DEPENDENT variable.
INDEPENDENT VARIABLE - something that is manipulated or changed in the experiment that is expected to have an effect on the dependent variable.
DEPENDENT VARIABLE - a measured variable, something that is expected to change as a result of the introduction of the independent variable.
300
What is the difference between a saturated and unsaturated fat?
Unsaturated fats have a carbon double bond that means the have few hydrogens in their hydrocarbon tail. This makes them bend and harder to stick together with LDFs. Saturated fats have more hydrogens, do not have a carbon double bond, and do not bend, which makes it easier for them to form LDFs and stick together.

List three differences between prokaryotic and eukaryotic cells.
Prokaryotic cells are bacteria whereas prokaryotic cells are plants, animals, and fungi
Prokaryotic cells appeared earlier in evolution
All prokaryotic cells have a cell wall and not all eukaryotic cells do.
Prokaryotic cells are ~10x smaller than eukaryotic ones.
Eukaryotic cells have membrane-bound organelles, such as a nucleus.

List three functions of carbohydrates AND corresponding types of carbohydrates that perform these types of functions.
- structural support (cellulose, chitin, peptidoglycan)
- storage of energy in a tissue (starch, glycogen)
- source of energy for cell (monosaccharides)
500
Organism A ingests 0.5 kilocalories a day and wastes 0.2 Kcal daily. Organism B ingests 6 kcal and expels 2 Kcal as waste. Which organism is more efficient and why?
Organism A wastes 40% of the energy it consumes whereas Organism B wastes ~33% of the energy it consumes. Thus, Organism B is more efficient than Organism A at consuming and using what it consumes to perform cellular work and/or growth.
500
Which organelle is a sphere-shaped structure within the cytoplasm of a cell or attached to the ER that is composed of RNA and protein and is the site of protein synthesis?
Ribosome
