What is a Hypothesis?

A testable prediction based on observations (more than a guess!!)that describes a cause and effect relationship between variables

100

What is water?

A molecule made of 2 atoms of hydrogen covalently bonded to 1 atom of oxygen.

100

What is a macromolecule and name 4.

A macromolecule is a large organic molecule (carbon containing) that makes up all living things. 

4 examples are:

Nucleic acids, proteins, carbs, and lipids.

100

What is the phospholipid bilayer?

2 layers that make up the plasma membrane of our cells.

100

What is a control group?

A group used for comparison with your experimental groups.  This is the “normal” group.

200

What is the difference between precise and accurate?

Accurate is how close your measurement is to the correct/accepted value.

Precise is how close your measurements are to each other.

200

what is the difference between something that is Polar and Nonpolar?

A polar molecule is Unequal distribution of charges.

A nonpolar molecule is no separation of charge, so no positive or negative poles are formed. 

200

What is the difference between a monomer and a polymer?

A monomer is a small, basic sub-unit.

–Think about a brick 

A polymer is a larger more complex structure made of monomers

–Think about a brick wall   

200

What is Adhesion?

The type of attraction that happens between two different molecules.

–Glass, soil, plant tissue, cotton, etc.

200

What is high specific heat?

The temperature of water does not change easily.

300

What is the difference between an independent variable and a dependent variable?

Independent is what the experimenter will deliberately change or manipulate in the investigation.

Dependent is what changes in responseto the independent variable.

300

What is a solution, solute, and solvent?

A solution is a uniform mixture of two or more substances. (lemonade)

A solute is what gets dissolved. (lemonade powder)

A solvent is what does the dissolving. (water)

300

What is the monomer and polymer of nucleic acids?

Monomer=Nucleotides 

Polymer=nucleic acid

300

What is matter?

Anything that has mass and occupies space.

300

What is the monomer and polymer of Proteins?

Monomer=Amino acids

Polymer=Polypeptide

400

What is the difference between qualitative and quantitative?

qualitative is when it describes the quality of something.

quantitataive is when it uses numbers to measure something.

400

What are the properties of water?

Cohesion 

Adhesion 

High specific heat 

Less dense as a solid 

Water is a terrific solvent

400

What is the monomer and polymer of carbs?

Monomer=monosaccharides 

Polymer=polysaccharides 

400

What is a principle?

A statement based on repeated experimental observation that describes an aspect of the world.

400

What is the main function of Nucleic acids?

They are informational molecules that store, transmit, and express our genetic information; instructions for making proteins.

500

What is the difference between Inference and observation?

Observation is the description of something you can see, smell, touch, taste, hear.

Inference is a guess about an object or outcome based on your observations.

500

What is the difference between hydrophilic and hydrophobic?

A hydrophobic Does not have an affinity for water

–Water “fearing”

–Does NOT dissolve in water

A hydrophilic Has an affinity for water

–Water “loving”

–Usually dissolves easily in water 

500

What is the monomer and polymer of lipids?

Monomer=fatty acids 

Polymer=triglycerides 

500

What is an experimental group?

groups that are being tested

500

True or False: Proteins have the most energy storage?

False, lipids do.
