• Draw a circle around all Heterozygous
genotypes above
• Draw a square around all Homozygous
genotypes.
Explain the difference between
dominant and recessive traits.
• Dominant traits =stronger allele,
represented by being written with a
CAPITAL letter (TT)
• Recessive Traits = weaker allele,
represented by being written as a lower
case letter. (tt)
A cross between a green eyed person
and a blue eyed person produces four
blue eyed children. What is most likely
the dominant color?
• Blue eyes
Capital letters represent
_______ alleles in a genetic
cross.
Lower Case letters represent a
__________ alleles in a genetic
cross.
Describe the difference between
phenotype and genotype.
• Phenotype =physical appearances
• Genotype =genetic alleles
Name the type of reproduction (asexual
or sexual) seen in each of the pictures
below.
Asexual reproduction involves
__ parent and results in ___
offspring.
• Sexual reproduction involves __
parent and results in ___ offspring.
The __________ is an organ in the
male reproductive system that
produces gametes (sex cells) called
___________.
• The __________ is an organ in the female
reproductive system that produces
gametes (sex cells) called ___________.
___________ fertilization is a type
of reproduction where eggs cells
are fertilized by sperm OUTSIDE of
the body.
In humans the _________ pair of
chromosomes determines the sex of
the offspring.
• __________ chromosomes will result in a
female offspring and __________ will
result in a male offspring.
Identify the following traits as
inherited or acquired.
• A: Nose Shape
E: Scar on Arm
• B: Hair Color
F: Skin color
• C: Eye Color
G: Attitude
• D: Personality
H: Curly Hair
If brown eyes are dominant, draw a
punnett square to show how two
brown-eyed parents can have a child
with blue eyes.
Label the Parts of a Flower
Describe the adaptations that have
allowed birds to survive in different
environments.
• Beaks
• Feathers
• Feet
Body System
Function
Transports materials to and from the body cells
Exchanges oxygen and carbon dioxide gases
Breaks down food and absorbs digestive materials
Removes wastes from blood
Enables the body to move: keeps the heart beating
Sends messages through out the body
Controls many body process by means of chemicals
Produces offspring
Supports and protects the body: makes blood cells
Fights disease and infection in the body
Protects and covers internal structures from the
outside environment
Label the type of joints seen in the
pictures below.
Word Bank: marrow, muscles,
phosphorus, support, calcium, internal
• Gives Shape and _________ to your
body.
• Protects your ________ organs
• _________ are attached to bones to help
them move.
• Blood cells are formed in the bone
__________.
• ___________ and _________ are stored
in the bones.
Name the organs through which a
piece of food would pass if you ate it.
• Mouth to esophagus
to stomach to small
intestine to large
intestine to rectum to
anus to toilet
How is food prevented from going
down the windpipe?
• Epiglottis
• the epiglottis folds down
to a more horizontal
position, with its
superior side functioning
as part of the pharynx.
In this manner it
prevents food from
going into the trachea
and instead directs it to
the esophagus, which is
posterior.
What causes food to move down
the esophagus?
• Peristalsis Muscles
What are the two functions of the
hydrochloric acid in your stomach?
• Chemical Digestion:
breaking down food
and breaking down
protein molecules
• Kills harmful bacteria
in the stomach
What are the two types of digestion?
Describe the difference between the
two.
• Mechanical Digestion =physical change
• Chemical Digestion =chemical change
• Mechanical breaks the food into smaller pieces
with changing it’s chemical make up.
• Chemical breaks the food down into a new
substance.
What are internal stimuli? Give an
example.
• An internal stimulus is something from
within that gets you do 'do' something. An
example of this would be "you feel a
hunger pain, so you go get some food".
What are external stimuli? Give an
example.
• An external stimulus is something from
outside (the environment) that gets you to
'do' something. And example of this would
be "you see a commercial about food, so
you go get some food".
Give 2 examples of animals that changed through
the process of natural selection and how these
have helped them to survive.
• Birds on the Galapagos
Islands
– Different beaks depending
on food available
– Tortoise on the Galapagos
Islands
• Neck and leg length
depending on food available
