Lamark claimed you acquired traits based on _______________
Need
100
Darwin could not explain
Variations
100
Comparing DNA, proteins, RNA of species
Comparative Biochemistry
100
You have samples of a population where 36% of the population have 5 fingers , a recessive condition.
What is the frequency of q?
.6 or 60%
100
How many more times acidic is a pH of 1 compared to 5
1. 4000 times
2. Teritary
100
Common Ancestor to all?
A
200
The oldest fossils are located here
Lower layers
200
If a species cant adapt to a changing environment this occurs
Extinction
200
2 causes of variations
Sexual Reproduction
Meiosis
Mutations
Crossing Over (we will learn)
200
When organisms need the same food this will occur
Competiton
200
You have samples of a population where 49% of the population have 5 fingers , a recessive condition.
What is the freequency of p?
.3 or 30%
200
How does Speciation occur?
(1 species into 2 species)
They must separate and for millions of years and not be able to interbreed
Each population will have their own random mutations
Populations must be isolated for long periods of time without gene exchange
200
Extinct Organism?
many answers
300
Separating pigments according to density
Chromatography

You have samples of a population where 81% of the population have 5 fingers , a recessive conduction.
What percentage of the population in Homozygous Dominant?
1% (.01)
300
Body part that no longer has use, but can show a common ancestor
Vestigial Structure
300
More closely related and why? E/I or E/C
E/I Because less common ancesotrs than E/C
400
Body parts that have similar structures, but different functions
Homologous
400
A term for the Survival of organisms genetically best adapted to the environment
Natural Selection
400
Which evidence (molecular or structural) is better to use to study evolution? Explain why and give an example of how your evidence is used
Molecular is more accurate (precise)
Comparative DNA, Amino Acids, Proteins, Enzymes>>>

Name 2 criteria needed for a species to survive in a changing environment
(More likely to survive in a changing environment)
Large Population
Variation
Sexual Reproduction
Short Reproductive Cycle
400
You have samples of a population where 81% of the population have 5 fingers , a recessive conduction.
What percentage of the population are Heterozygous?
18%
400
Explain why insecticides are no longer killing the cockroaches in the school and we are seeing more and more
The have a variation,they reproduced and survive
500
Body parts that have similar functions but different Structures (ex:Bird and Butterfly Wing)
Analogous Structures
500
Name at least 3 of Darwins concepts
Overproduction
Competition
Variation
Reproduction
Natural Selection
Speciation
500
Explain how antibiotic resistant bacteria is increasing in frequency
Mutants, survive, reproduce, and pass on resistant gene to offspring
500
Where in the body do mutations have to occur in order for it to effect offspring?
Gametes
500
What is the purpose of Hardy Weinberg Equilibrium
See if Evolution is occuring
500
3 criteria of 1st organism
