Do organisms "decide" to evolve and change?
a)
Yes, they know they need to change to survive

It survives and its DNA is passed on

c)

It changes its traits to adapt and survive

18.

If a new trait DOES NOT help an organism survive, what may happen to it?

a)

It dies and its DNA is not passed on

b)

It survives and its DNA is passed on

c)

It changes its traits to adapt and survive

19.

DNA

b)

tRNA

c)

protein

d)

rRNA

20.

21.

All rabbits of the same species living in a particular area would be an example of a(n)

a)

population

b)

22.

Mutations are important because they bring about

a)

death of the organism in which they develop

genetic variation needed for a population to evolve

so that their babies can have friends to play with
b)
the more offspring the more likely the offspring will survive
c)
the more offspring the less likely offspring will survive

Why is competition important for natural selection?

a)

It shows which variations are more successful, allowing the organisms with those variations to survive.

b)

It causes organisms, regardless of which traits they have, to die out, reducing the population size.
