Answer 13

false

Question 14

Answer 14

false

Question 15

Answer 15

false

Question 16

what are some aspects of the theory of evolution

Answer 16

There was a “big bang”

Earth is millions of years old

there is evidence

the evidence is testable

Question 17

What are some aspects of the creation theory

Answer 17

an all powerful being made everything

earth is very young (thousands of years)

there is no evidence

it is not testible

Question 18

what is evidence for evolution

Answer 18

Fossil Records prove that organisms change over time

Biomolecular molecules like DNA, RNA, ATP, and amino acids are the same in all living things

Convergent and divergent evolution

when developing, vertebrates look the same

Question 19

what was the goal of Stanley Miller’s apparatus

Answer 19

to create organic compounds from inorganic compounds

Question 20

was Stanley Miller successful

Answer 20

yes

Question 21

What are the criteria necessary for Hardy Weinberg’s equilibrium

Answer 21

No mutations

Genes are all equal

Random mating

allele frequency stays the same

Very large

Question 22

is it possible for a population like the Hardy Weinberg to exist in nature

Answer 22

no
