Name three major differences between Prokaryotic and Eukaryotic cells.
What is... Eukaryotic cells have a "true" nucleus, have organelles and are much bigger/complex. (plants, animals, fungi and protists) Prokaryotic cells do not have a nucleus, organelles and are small/simple single celled organisms. (bacteria and archaea)

Exam 1: Explain how ________ act as catalysts by lowering the activation energy.
What is.... Enzymes lowering the activation energy, lower the requirement for reactants to become products. Similar to how if the requirement to transfer was lowered, students would be able to transfer more quickly!
200
The differences between Independent and Dependent variables...
What is... Independent variables are the "built-in" variables that the scientist can change and are normally on the x-axis. Dependent variables are the "result" variable that is collected at the end of the experiment and are normally on the y-axis.
200
A spontaneous movement of molecules across a membrane that doesn't require energy. Three types: simple diffusion, osmosis and facilitated transport.
What is... Passive transport, high to low concentration. "goes with the flow"

In a situation where brown hair is dominant over blonde hair, the offspring have the following genotypes: "Bb and bb" What are the genotypes and phenotypes of the parents.
The parents are heterozygous dominant for (brown hair)Bb and homozygous recessive for (blonde hair) bb
200
Exam 2: The relative concentration of solutes outside of the cell relative to inside the cell. Isotonic, Hypotonic and Hypertonic.
What is... tonicity
300
Name and describe three types of chemical bonding.
What is.... 1. Ionic bond- a strong chemical bond that involves the complete giving and taking of electrons to fill valence shells. 2. Covalent bond- a strong chemical bond that involves sharing of electrons to fill valence shells. 3. Hydrogen bond- a weak chemical bond that involves the attraction between two polar molecules.

What is... RNA Polymerase, Transcription.
300
1. There must be variation or diversity in a population 2. that variation must be inheritable 3. Individuals of the trait must produce more offspring than those with a different version of that trait.
What are... three conditions of Natural Selection

Name and describe the four macromolecules studied for Exam 1.
What is... 1. Carbohydrates- contain CHO(sugars), primary fuel for organisms and provide short-term energy. 2.Protein- provide structure, protection and transport 3.Amino Acids- building blocks of proteins;20 different amino acids differentiated by the R group. 4. Lipids- (fats) provide long-term energy storage/insulation, (sterols) regulate growth/development,(phospholipids) form cellular membranes.
