Allowing for gas exchange in fish
What are gills

What is asexual reproduction?
Requires only one parent, offspring are uniform (clones)

What is Sexual reproduction
What is phenotype?

In the snow, a bunny has evolved over time to have a white coat... why is this?

What is an advantage of asexual reproduction?
Faster, Requires on parent, More offspring
Where is the location of genetic material in a cell?
Inside the nucleus
Why do animals migrate?
A response to season change
What is survival of the fittest?
Populations adapt or develop traits over time by Natural Selection in order for the species to survive.
What organelle would be responsible for determining eye color
Nucleus
What is a disadvantage of asexual reproduction?
Slow, Requires 2 parents
Children that are colorblind also have a family member that are colorblind or is a carrier. What does this suggest?
Heredity is predetermined
Why do birds have different beaks?
To eat different food
What is mimicry
When a harmless animal mimics (copies) a more dangerous animal
What is phloem
Food moving downward from the leaves to the roots

What is heredity?
How traits get passed from one generation to another
What is Xylem?
Water moving UPWARD from roots to plant
