200

Convert 250cm to mm.

2500 mm

200

Define isotope.


Multiple forms of the same element containing equal numbers of protons but different numbers of neutrons. Differ in atomic mass, same atomic number.


200

Define active transport.

Movement of ions through proteins against the concentration gradient using ATP.

400

Calculate the total magnification for the 40x objective.

40x * 10x = 400x

400

List the two microscopic stains/dye. 


Congo Red (Lugo's Iodine)

Methylene Blue

400

List the four major macromolecules. 

Carbohydrates

Lipids 

Proteins

Nucleic Acids


400

Define and give one example of a hypertonic solution.

Red blood cell in an extremely concentrated solution, water leaves cell and cell goes flat.

600

What is depth of field?

Distance between the nearest and farthest elements in a scene that appear to be sharp in an image. 


600

How is a theory different from a hypothesis?


A hypothesis answers a question, its an assumption or prediction that can be tested through scientific experimentation.

A theory is a well tested explanation. Theories have been confirmed through evidence/studies/experimentation.

600

Which macromolecule is this?

Nucleic Acid


600

The four factors affecting diffusion rate.

Concentration gradient

Molecular size/permeability

Temperature

Pressure Gradient

800

Describe how you would prepare a wet mount.

Place the object in drop of water on clean slide.

Hold a coverslip at 45 degree angle with fingertips.

Lower the coverslip slowly.

800

List the four functional groups of an amino acid.

Hydrogen

Carboxyl

Amine 

R Group

800

What are the three types of passive transport and how does each work?

Simple diffusion - Diffusion of lipid soluble molecules through the lipid bilayer membrane

Facilitated diffusion - Diffusion of water soluble molecules through a carrier protein

Osmosis - Diffusion of water across a selectively permeable membrane, more permeable to water

1000

Two kinds of microscopes we used and what are they used for.

Compound/light microscope

Stereomicroscope


1000

List all 6 differences between plant and animal cells.

Plant: Centrioles absent. Cilia/flagella absent.

Animal: Cell wall absent. Chloroplasts absent. Plastids absent. Central vacuole absent.


1000

What color does bromothymol blue become in 

acidic,

basic,

neutral solutions?

Acidic - yellow

Basic - blue

Neutral - green


1000

Describe the results of the glucose, starch, iodine experiment, the direction of flow of each molecule. 

Was the solution hypotonic or hypertonic and how do you know?

The dialysis tubing was permeable to glucose and iodine but not to starch. Starch has a larger molecule size. 

Molecules entered the tubing causing swelling in the hypotonic solution.
