LIST ALL 8
CHARACTERISTICS OF LIFE
1. Living things are made up of cells
2. Reproduce
3. Universal genetic Code
4. Grow and develop
5. Obtain and use energy
6. Respond to their environment
7. Stable internal environment
8. Change over time
IONIC VS COVALENT
1. Define Ionic and Covalent
Ionic bonds are between metals and non-metals.
They have a high melting point, transfer/steal
electrons and are stronger than covalent bonds.
Covalent bond are between non-metals and they
share their electrons.
2. Give an example of an Ionic and Covalent bond
Ionic- NaCl, CaCl2, K2S
Covalent: CO2, H2O, O3, H2SO4
PROCESSES
1. List the correct sequence in cellular Respiration.
Glycolysis, Krebs, then lastly Electron Transport Chain (ETC)
2. Write out the equation for photosynthesis
CO2 + H2O + Energy (light)  C6H12O6 + O2
3. Write out the equation for Cellular Respiration
C6H12O6 + O2  CO2 + H2O + Energy (ATP)
NUCLEOTIDES
1. Draw the 3 parts of a nucleotide
2. Draw 4 nucleotides (include correct number of
Hydrogen Bonds
A-T Have 2 bonds, C-G 3 Hydrogen
bonds

GENETICS
A woman is heterozygous for Tay-Sachs (a recessive
disorder). What are the chances of her giving birth to a child
with Tay-Sachs if the father is normal (homozygous
dominant?) What are the chances of giving birth to a carrier?
Woman: Tt Man: TT No chance of child with
disease; 50% chance of carrier
Both you and your sister have attached earlobes, yet your parents
have unattached ones. Unattached earlobes are dominant over
attached. Give the genotypes of you, your sister, and your parents.
Genotypes of you and sis uu Genotypes of
parents Uu
MORE GENETICS
A woman with PKU (kk) marries a man who is genotypically
normal (KK). Which best describes the chances that their
child will: be genotypically normal (KK), be a carrier for PKU
(Kk), or have the disease PKU (kk) ?
25% genotypically normal KK, 50% carrier Kk, 25% PKU
kk
VARIABLES
1. My cat Harry is a picky eater. I’ve noticed that he eats
better when the TV is on. To test this, I set out 0.25 kilograms
of food and left the TV on for 4 hours. I measured how much
food was left. The next day, I set out 0.25 kilograms of food
and left the TV off for 4 hours. I measured the amount of food
left. After Day 1, there were 0.08 kilograms of food left and
after Day 2, there were 0.12 kilograms of food left.
List Independent, Dependent and controlled variables
I.V= Presence of TV
D.V= Food left over (mass=Kg)
Controls= Time, same scale, same cat, time of day
VARIABLES
2. Suppose you planted three rows of peppers in your
garden. Row 1 was planted with ChemLawn fertilizer and
Row 2 was planted with Ortho brand fertilizer. Row 3 did not
receive any fertilizer. All other conditions in the field (type of
see, soil, light, and water) are the same. Row 1 plants
produced an average of 3 fruits per plant. Row 2 plants
produced an average of 10 fruits per plant. Row 3 produces
an average of 1 fruit per plant.
List Independent, Dependent and controlled variables
I.V= Type of Fertilizer
D.V=number of fruits per plant
Controls= same soil, light, water
MEASURING REVIEW
Convert the following:
1. 12 cm= _______km
2. .85mL= _____ dkL
3. 1.4Kg= ______ dG
1. 0.00012
2. 0.000085
3. 14000.00
List the measurements for Length, Mass, and Volume in English and
Metric System
Metric= mass (grams) length (meter) volume (liter)
English= mass(lbs) length (yard/miles) volume
(ounces/cups)

RANDOM QUESTIONS
1. Describe a catalyst.
2. Name the first person to see a cell
3. Explain the phospolipid bilayer
4. Explain the difference in exergonic/endergonic reactions
1. Speeds up a reaction
2. Robert Hooke
3. Bilayer the inside is hydrophobic (fear of water) outside is
hydrophilic (love water)
4. Exergonic releases or gives off energy/ endergonic takes in energy
and heat
