______________.
A segment of this
DNA is called a
GENE
_______________.
A chromosome
contains many
GENES
____________
The cells of these organs are
genetically
identical
____________________.
However, they look and function
differently because:
they each express a
different set of genes
Ecological Succession
Pioneers
Stage 1 vegetation are called ________________
While stage 5 vegetation is called the ________________
Climax vegetation
Food Chain
Based on the hawks feeding
Habits it could be called 4
Different names. Can you name
Them?
A. Carnivore
B. 4 level Consumer
C. Predator
D. Heterotroph
Grasshopper eats grass
Grass
ECOSYSTEM
What makes this
an ecosystem?
It has both biotic
and abiotic factors
Biotic means
Living
Abiotic means
Non Living
Ecological Succession
Abiotic Factors
(Nonliving)
PHOTOSYNTHESIS
What is the word equation for photosynthesis?
Carbon Dioxide + Water + Light Energy
Glucose + Oxygen + Water
PREDATOR/PREY
PARASITISM (+, -)
GLOBAL WARMING
Caused by ________________________
Greenhouse
gases like ______________,
Carbon Dioxide _____________
Methane gas
Water vapor
Chlorofluorocarbons (CFCs)

Comparative Anatomy
According to evolution they are similar because they have a __________________,
Common ancestor
But they are different because each has __________________________________
Adapted to specific environments or niche.
Protein Synthesis
Name the red structure:
Name the green structure:
Name the Orange structure:
Name the purple structure:
Messenger RNA (mRNA)
Transfer RNA (tRNA)
Ribosome
Amino acids forming a
polypeptide or protein
MUTUALISM (+, +)
Consequences
of GLOBAL
WARMING
EVOLUTION
These remora fish attached to this shark do not harm the shark.
However they benefit as
They get a free ride and left over food as the shark feeds.
Based on the description above this relationship can be described as:
Commensalism (+, 0)
Note: We use a zero for the shark because
he is not harmed nor does he
benefit
OZONE LAYER DEPLETION
Chlorofluorocarbons (CFCs)
Caused by ______________________________________
DEFORESTATION
Reforestation
The opposite of deforestation is ________________________
Gradualism
Punctuated
Equilibrium
Industrial Melanism
Stanley Miller’s experiment
What hypothesis was this experiment working on?
The Heterotroph Hypothesis
FERTILIZATION
The cell that results from fertilization is known as a

Crossing Over or recombination
during MEIOSIS
Variation
This process results in __________________________

Mitochondria site of________________
Cellular Respiration
Do you know the word equation for respiration?
Glucose + Oxygen
ATP + Carbon Dioxide + Water
DNA or Deoxyribonucleic acid
List 3 ways it differs from RNA
1. It is double stranded, RNA is single stranded
2. DNA uses Deoxyribose as its sugar, RNA uses Ribose
3. DNA uses Thymine (T), RNA uses Uracil (U)
C

B
A: Uterus, site of development of the fetus
D
B. Ovary: Produces hormones and also stores and releases eggs.
C. Fallopian Tubes or Oviduct, site of fertilization
D. Vagina: Receives sperm and it is the birth canal.

mRNA
Red and White
tRNA
Ribosome
Green
Yellow
DNA Replication
Diffusion
Placenta
What is the
function of the
placenta?
It is the site of
Exchange of nutrients
And waste products
Between the baby
And the mother.
Respiratory
System
Name two systems that work
Closely with the respiratory
System.
Circulatory System
Brings Carbon Dioxide to the
Lungs and gets Oxygen
Nervous System
Monitors level of Carbon Dioxide
In the blood to determine our
Breathing rate.
What does each system do?
Mitochondria
Cellular Respiration
Site of ______________
C6H12O6 + 6O2 -----> 6CO2 + 6H20 + energy (heat and ATP)
The equation above represents:
Cellular Respiration
There are two kinds of cellular respiration. Name them.
Aerobic Respiration
Requires Oxygen
Anaerobic respiration
Does not require Oxygen
How are the two different?
PLANT CELL
1. Nucleus
2. Nucleolus
3. Cell Membrane
4. Cytoplasm
5. Cell Wall
6. Vacuoles
7. Chloroplast
Osmosis
Because it deals with the diffusion of WATER

This organism makes
its own food. Based
On this type of
nutrition we give this
plant two names.
What are they?
Producer
Autotroph
Name that
System
Muscular
Skeletal
Digestive
Circulatory
Female

Male
Reproductive
Homeostasis
Name the producer
in this pyramid.
Grasses because they
are autotrophs
Who can be considered a
2 level consumer?
Chipmunks are 2 level,
While insects are 1st level
Which individual would
Be the least numerous?
Grizzly bears would be
The least because of
Energy and biomass loss
From one trophic level top
the next.
