The molecule which stores genetic information
DNA
The naturalist that came up with the theory of Natural Selection
T/F
A variation that is beneficial or allows the organism to survive in their environment is called an adaptation
true.
Evolution
When an organism blends in with its environment, it's called...
Camouflage
A section of DNA which codes for proteins
Gene

G pairs with C
The building block of DNA

On the Galapagos Island, Darwin noticed some animals had variations depending on their environment/climate. Can you name one of the animals?
Examples include finches, tortoises, and iguanas
A. A jackrabbit licks its paws so it can stay cooler
B. A jackrabbit has brown fur to blend with the dirt
C. A jackrabbit has a lot of blood vessels in its ears to help it cool its blood
A. A jackrabbit licks its paws so it can stay cooler - BEHAVIORAL
B. A jackrabbit has brown fur to blend with the dirt - STRUCTURAL
C. A jackrabbit has a lot of blood vessels in its ears to help it cool its blood - FUNCTIONAL
An organism's ability to survive in its environment
Fitness
Hair color, physical traits, size, and shape are types of _______ adaptations
Structural
Each nucleotide consists of these 3 things
Phosphate, sugar, base
Explain how pollution from the Industrial Revolution affected the white/black peppered moth populations.
The pollution darkened the trees, which made the light moths visible to birds. The dark moths had an advantage because of camouflage and so, their population survived more.
Give a structural, behavioral, and functional adaptation of any organism of your choice
Answers may vary...but structural is physical appearance, behavioral is an action, and function is internal body systems
A theory that states organisms with traits suited to their environment survive and pass on its genes
Theory of Natural Selection
Genes code for _______, which give us our traits
protein
