Question 1 - 10
• What are the 6 essential elements?
Answer 1 – 10
•
•
•
•
•
•
Carbon
Hydrogen
Oxygen
Nitrogen
Calcium
Phorphorus
Question 1 - 20
• How many protons, neutrons, and electrons
are in fluorine?
Answer 1 – 20
• Protons: 9
• Electrons 9
• Neutrons: 10 (atomic mass is 19)
Question 1 - 30
• Draw and label a picture of a beryllium atom
labeling the protons/neutrons/electrons
Answer 1 – 30
• Protons: 4
• Electrons: 4
• Neutrons: 5
(atomic mass = 9)
Question 1 - 40
• What bond would form between chlorine (Cl)
and hydrogen (H)? Would the electrons be
shared or transferred.
Answer 1 – 40
• Both H and Cl are nonmetals so a covalent
bond would form in between them. Electrons
are SHARED in a covalent bond.

Question 2 - 10
• What are the 4 types of macromolecules?
Answer 2 – 10
•
•
•
•
Carbohydrates
Lipids
Proteins
Nucleic acids
Question 2 - 20
• What is the difference between a monomer
and a polymer?
Answer 2 – 20
• Monomer: a single molecule that can be
combined
• Polymer: composed of many monomers (a
monomer chain)
Question 2 - 30
• Name the polymer for each of the
macromolecules
Answer 2 – 30
• Carbohydrates: disaccharides and
polysaccharides (starch)
• Proteins: polypeptides
• Nucleic acids: DNA
• Lipids: saturated fats
Question 2 - 40
• Name all of the monomers for the 4
macromolecules.
Answer 2 – 40
•
•
•
•
Carbohydrates: monosaccharides
Proteins: amino acids
Lipids: fatty acid and glycerol
Nucleic acid: nucleotide

Carbohydrates
Proteins
lipids
Nucelic acids
sugar
Meats/bean
s

Question 3 - 10
• Draw the structure of a water molecule
Answer 3 – 10
Question 3 - 20
• What is the bond called the occurs in a water
molecule?
Answer 3 – 20
• Polar covalent bond/hydrogen bond
Question 3 - 30
• What are the 4 properties of water.
Answer 3 – 30
•
•
•
•
Cohesion/adhesion
Expansion upon freezing
Temperature moderation
Universal solvent
Question 3 - 40
• Why is cohesion/adhesion important for
plants?
Answer 3 – 40
• Plants need to pump water against gravity.
Because water sticks to itself (cohesion) and
can stick to other things like the inside
structure of a plant (adhesion), water is able
to get from the roots to the leaves.
Question 3 - 50
• WHOLE CLASS CHALLENGE
– State the importance for each of the 4 properties
of water.
Answer 3 – 50
Cohesion/adhesion Plants can get water from roots to
leaves
Expansion upon
Fish in lakes are insulated in the
freezing
winter when the surface freezes
Temperature
Climate and cell temperatuer
moderation
regulation
Universal solvent
Blood = mostly water and
therefore able to dissolve
substances and nutrients
required for cell processes
Question 4 - 10
• Draw and label a picture of a pH scale
Answer 4 – 10
Question 4 - 20
• What is the difference between an acid and a
base?
Answer 4 – 20
• Acid
– pH 1-6.9
– Generates H+ ions
– sour/corrosive
• Base
– pH 7.1-14
– Accepts H+ ; generates OH– Bitter/slippery
Question 4 - 30
• Give an example of an acid and state why it is
important
Answer 4 – 30
• Stomach acid; digests food
• Fatty acids; cell membranes
• Citric acid; cell metabolism
Question 4 - 40
• Give an example of a base and state why it is
important.
Answer 4 – 40
• Magnesium oxide; neutralizes stomach acid
• Sodium hydroxide (lye); cleaning product
• Ammonia; cleaning product/fertilizer
