Proteins

200

List out the steps to the scientific method.

(hint: there are 7 steps)

Find a problem or question, research, hypothesis, experiment, analyze, conclusion, share

What is the function of lipids?

Storing energy

200

What is the difference between cohesion and adhesion?

Cohesion - water sticks to water

Adhesion - water sticks to something that is not water

200

What do enzymes do for a chemical reaction?

(hint: they catalyze) 

They speed up a reaction

300

Describe an independent and dependent variable.

Independent variable: variable that the scientist changes

Dependent variable: variable that is measured

300

What is the monomer of carbohydrates?

Monosaccharides 

300

What is specific heat with water? 

Water can take a lot of energy (or heat) before it changes temperatures/boils

300

Which is the reaction with the enzyme? 

B - red line

What do graphs do for scientific data?

Help visualize data and highlight patterns

400

Which macromolecule has an amino acid as its monomer? 

Proteins

400

What does the universal solvent mean?

Water can dissolve almost anything
400

What happens when the temperature or pH changes with an enzyme? 

It becomes denatured - aka, it no longer works

How would an experiment be set up to measure plant growth with different fertilizers? Create the problem/question, hypothesis, IV, DV, an experimental plan, control.

Problem/question: what fertilizer helps plant growth?

Hypothesis: If I add miraclegrow, the plant will grow faster

IV: Fertilizer types

DV: Plant height

Control: No fertilizer

Experimental plan: add a gram of fertilizer once a week, measure height every week for a month

500

Which macromolecule has the following elements in it? 

N, O, C, P, H

Nucleic acids

What does polarity mean? 

The negative charge of water and the positive charge of hydrogens cause an unequal pull

500

Enzymes only work with a certain C. What is C called? 

Substrate
