analogous structures
vestigal structure
homologous structures
protein structures
Which two organisms are most similar?
human and gorilla
gorilla and chimp
common ancester and gorilla
human and chimp
where do the genes come from that makes an organism more adapted to it's environment
it's mutated in the individual
the entire poplulation mutates all at once
it's inherited from ancestors
they just appeared
Years ago, Betty Sue had skin cancer from being in the sun all day and not using sun block. Can Betty Sue pass skin cancer on to her offspring?
yes the cancer was in the DNA of the skin,
yes, the cancer was inherited
no, the cancer can only be in skin
no, the cancer is not in the gametes
What are the 2 conditions that must be met for a population to be "fit" from Natural Selection
eat more and drink more water
survive and reproduce
fight for the females
the biggest survives
"only physical appearance can be inherited"
Is this an accurate statement?
yes, that's why zebras are black and white
yes, that's why giraffe's have long necks
No, an otter cracking open an urchin with a rock is behavioral can be inherited
yes, when a dogs sits on command is a learned behavior
Why did the crocodile get smaller?
one human was not enough to eat
the earth got smaller
the land mass got larger

Mendel's law of dominance
Mendel's law of segregation
Newton's first law of motion
Darwin's theory of Natural Selection
Why does Leche look like a coral snake?
because he can!
to be pretty
predators can't think
he mimics a coral snake for protection
