Worksheet time: 3600secs
Which is an example of artificial selection?
Rock Pocket Mice
Darwin's finches
Darwin's tortoises
Modern bananas
Which is the best explanation for bacterial resistance to Antibiotics?
Humans breed bacteria as biological weapons
Bacteria are naturally resistant to most antibiotics
Use of antibiotics increases the chance of a resistant strain being created
Use of antibiotics selects for only resistant bacteria strains that then become more common.
The main idea of Darwin's book was:
All animals are equally important
The Galapagos Islands are unique and should be preserved.
Men evolved from monkeys
Natural selection could force species to change over time.
Lamarck was correct about which of the following?
Traits could be passed on from one generation to the next.
Organisms could change due to their desires
If an organism was effected by the environment, that effect would be passed on to its offspring.
Giraffes stretched their necks, which therefore got longer.
Some rock pocket mice had a mutation that gave them dark fur. This trait helped them to colonize dark rock formations. This mutation turned out to be:
An adaptation
A mutation
A deleterious mutation
A hindrance
Scientist at a crime scene find a hair folicle. There is DNA in the root but not enough to perform a gel electrophoresis. Which process would create enough copies of the DNA so that tests could be performed on it?
PCR
ATP
Gel Electrophoresis
DNA has what type of electric charge?
Negative
Positive
Neutral
Covalent
Towards which end will DNA move when undergoing gel electrophoresis?
The postive end
The negative end
Which strands of DNA will be found closest to the positive end of the agarose gel during electrophoresis?
Short
Long
Which is not a benefit of genetically modified organisms?
More nutritious crops
Larger crops
Drought and pest resistant crops
All choices are correct
If both dominant alleles are expressed in an organism's phenotype, the type of inheritance is:
Codominance
Incomplete dominance
Sex-linked
Recessive
In rock pocket mice, dark fur is dominant to tan fur (not really). If 2 dark rock pocket mice have a tan rock pocket baby, what is the chance their next baby will also be tan?
100%
75%
50%
25%

Red-Green colorblindness is a recessive, sex linked trait found on the x-chromosome.
If a carrier female has a child with a non-colorblind male, what percentage of their kids will be colorblind?

XbY= colorblind male
XBY=normal male
25%

Haploid cells that combine with cells from another individual (to form a zygote) are called:
Gametes
Somatic cells
pollen
Sex Chromosomes
What is recombinant DNA
DNA from 2 different organisms combined
DNA from 2 different ribosomes
DNA that is separated out from a vector
Which enzyme glues DNA together?
Ligase
Polymerase
Helicase
