darwin
lyell
lamark
wallace
7
what is the problem with the current tuberculosis treatment?
it requires isolating the individual, which is not ethical
Some strains of TB bacteria are antibiotic resistant
TB causes symptoms in all infected people, increasing demand
The TB virus mutates too rapidly for successful treatment
8
What type of cell makes antibodies?
Helper t-cells
all types of t-cells
b-cells
memory t-cells
9
A new population that results after being isolated by distance or geography is:
convergence
allopatric
sympatric
divergence
10
A correlation study:
is the same as an experiment
has an independent and dependent variable
can determine if one variable causes the other
can be used to measure the association b/w smoking & cancer
11
What do bacteria have that viruses don't have?
genetic material
reproductive machinery
protein capsid
pathogenic ability
12
Which term is incorrectly matched with its definition?
allele: variation of a gene
artificial selection: selection imposed by human choice
adaptation: traits that increase fitness in an environment
fitness: how strong an organism is
13
Which is a difference between prokaryotes and eukaryotes?
prokaryotes are a type of cell, eukaryotes are a virus
prokaryotes can be pathogenic, eukaryotes are not
prokaryotes do not have genetic material, eukaryotes do
prokaryotes do not have a nuclei, eukaryotes do
14
What is a limitation of the biological species concept?
it is not effective for species that are asexual
Hybrid plants can be fertile
all of the above
it cannot be applied to historical species or fossils
15
Which is NOT true of a hypothesis:
it requires deductive reasoning
It can be tested using experiments
It must be falsifiable
it can be proved right
16
Which stage has a SPECIFIC defense?
all of them are specific
stage 3
stage 2
stage 1
17
How can I reduce bias in my study?
double-blind procedure
giving the control group a placebo
random assignment of participants
all of the above
18
The preference to mate with someone like self is called:
Assortative mating
Sexual selection
gene flow
natural selection
19
which term is incorrectly matched with it's definition:
sampling error: sample is not representative of the whole
population: all the participants in your study
theory: well-supported explanation of a phenomenon
mean: the arithmatic average (sum of values/# of values)
20
Which does NOT occur during the second stage of the immune response?
inflammation
mucus membranes block invaders from getting into body
interferons produce anti-viral chemicals
macrophages phagocytize foreign particles
21
Which prefertilization barrier is incorrectly matched with its definition?
spatial: egg and sperm don't recognize each other
behavioral: courtship displays are species specific
mechanical: reproductive anatomy does not align
temporal: species reproduce at different times or seasons
22
what does it mean if your results are statistically significant?
your hypothesis has proved to be correct
the treatment probably had no effect
it is unlikely that the difference bw groups is bc of chance
the means of the two groups look very different
23
Which is the definition of gene pool?
change in allele frequency
sum of the alleles found in all individuals of a species
preference to mate with someone like self
the spread of an allele throughout a population
24
