- Cthe number of protons, neutrons, and electrons
2What does the atomic number mean?
- AThe number of electrons the atom has
- BThe number of protons the atom has

- Aionic, van der waals, hydrogen, covalent
- Bvan der waals, hydrogen, ionic, covalent
- Chydrogen, ionic, van der waals, covalent
- Dcovalent, ionic, hydrogen, van der waals
5Water is a [blank_start]polar[blank_end] molecule. When water molecules stick together, it is called [blank_start]cohesion[blank_end]. When water molecules stick to other objects it is called [blank_start]adhesion[blank_end]. Capillary action is when water is soaked up in a plant through [blank_start]adhesion[blank_end] and [blank_start]cohesion[blank_end] working together. (hint for last part: alphabetical order)
- Apolar
- Bcohesion
- Cadhesion
- Dadhesion
- Ecohesion
6Hydrophilic means __________________
Hydrophobic means _______________- Awater "loving" (dissolved in water), "hating" water (repels, wants to get away from water)
- B"hating" water (repels, wants to get away from water), water "loving" (dissolved in water)
7When water molecules at the top of water cohere together to avoid outside molecules, it is called [blank_start]surface tension[blank_end].
- Asurface tension
8What are the four essential organic compounds for life?
- ACarbohydrates
- BProteins
- CNucleic Acids
- DWater
- ELipids
- FAlcohol
9Carbohydrates create [blank_start]sugars[blank_end] for energy. Lipids store [blank_start]energy[blank_end] with fats. Proteins are important for the [blank_start]structure[blank_end] of cells. Nucleic acids contain the [blank_start]genetic[blank_end] code for cells.
- Asugars
- Benergy
- Cstructure
- Dgenetic
10What is the difference between phospholipids and triglycerides?
- APhospolipids have a phosphorus "head" and 2 tails of fatty acids
- BTriglycerides have 3 tails of fatty acids
- CTriglycerides store fat
- DPhospholipids create the cell membrane
- EAll of the above
11Deoxyribonucleic acid and ribonucleic acid are two types of nucleic acids
- AVerdadeiro
- BFalso
12Enzymes are biological [blank_start]catalysts[blank_end], which help to speed up metabolic reactions. Enzymes [blank_start]denature[blank_end] (lose characteristics) when the conditions are not right.
- Adenature
- Bcatalysts
13Enzymes will denature based off changes in
- ATemperature
- BTime
- CBrightness
- DSalinity
- EpH
14Enzymes have [blank_start]active[blank_end] sites. In these sites, [blank_start]substrates[blank_end] fit in and cause chemical reactions to occur. The speed of reaction can depend on the presence of [blank_start]inhibitors[blank_end].
- Aactive
- Bsubstrates
- Cinhibitors
15Levels of protein structure:
Primary - [blank_start]amino[blank_end] acid sequence
Secondary - [blank_start]hydrogen[blank_end] bonds in peptide chain form alpha-[blank_start]helix[blank_end] and beta sheets.
Tertiary - non-[blank_start]covalent[blank_end] interactions between [blank_start]variable[blank_end] group within protein
Quaternary - interaction between [blank_start]two[blank_end] polypeptide chains- Ahelix
- Bamino
- Chydrogen
- Dcovalent
- Evariable
- Ftwo
16What two saccharides create lactose?
- Aglucose+glucose
- Bamino acid+galactose
- Cwater+sucrose
- Dglucose+galactose
- Emaltose+sucrose
17[blank_start]Waxes[blank_end] are lipids that [blank_start]waterproof[blank_end] plants.
- AWaxes
- Bwaterproof
18Acids have less H+ ions and bases have more H+ ions
- AVerdadeiro
- BFalso
19Whats the difference between dehydration synthesis and hydrolysis?
- Adehydration synthesis creates new polymers
- Bhydrolysis involves taking away a water molecule
- Cdehydration synthesis involves taking away a water molecule
- Dhydrolysis breaks down polymers
20the pH scale is measured from 0-20
- AVerdadeiro
- BFalso
