Which of the following list of levels of biological organization are in correct order from smallest to largest?
organism, tissue, cell, molecule, atom
organism, population, community, ecosystem
biosphere, organ, organism, cell
tissue, cell, atom, molecule
organism, population, community, ecosystem
Which of the following statements best describes the logic of the scientific method?
If my prediction is correct, it will lead to a testable hypothesis
If my hypothesis is correct, I can expect certain test results
If my observations are recorded accurately, they will support my hypothesis.
If I generate a testable hypothesis, tests and observations will support it.
If my hypothesis is correct, I can expect certain test results
Which of the following statements best distinguishes hypotheses from theories in science?
Hypotheses and theories mean basically the same thing.
Theories are hypotheses that have been proved.
Hypotheses usually are narrow in scope; theories have broad explanatory power.
Hypotheses are tentative guesses; theories are correct answers to questions about nature.
Hypotheses usually are narrow in scope; theories have broad explanatory power
Which of the following is a true statement about Charles Darwin?
He was the first person to think it possible that life evolves or changes
He was the first to realize that living things were made of cells
He formulated the hypothesis that natural selection was the major mechanism of evolution
He described the structure of DN
He formulated the hypothesis that natural selection was the major mechanism of evolution
What could you say to someone who says that evolution is “just a theory”?
Theories are well-tested and never disproven explanations.
You are right; little evidence exists supporting evolution
Theories are proven and will never change.
Theories are well-tested and never disproven explanations.
As a mechanism of evolution, natural selection is most directly related to
intelligence
unequal reproductive success
survival
incredible speed and strength
unequal reproductive success
The genetic makeup of an organism is called its genotype, whereas the physical traits of an organism are called its
chromosome
phenotype
alleles
homozygous
phenotype
Whether an allele is dominant or recessive depends on
whether it is inherited from the mother or the father; the father’s allele is always dominant
whether it or another allele determines the phenotype when both are present
how common the allele is
whether it or another allele determines the phenotype when both are present
A woman who has type B blood and a man who has type O blood could possibly have children of which of the following phenotypes?
O only
B or O
AB
B only
B or O
Which of these lists shows the 3 domains of life?
Bacteria, Archaea, Eukarya
Bacteria, Fungi, Plantae
Animalia, Plantae, Fungi
Protista, Euglenia, Protozoa
Bacteria, Archaea, Eukarya
What do I mean when I say that bacteria are important nitrogen fixers?
Nitrogen is very toxic to plants and bacteria prevents it from entering the leaf.
Nitrogen is a slippery element and bacteria attach fimbrae to it and make it stick to plants.
Bacteria can take free nitrogen from the atmosphere and turn it into forms useable by plants
Most nitrogen is broken because it does not have enough electrons. Bacteria can fix this.
Bacteria can take free nitrogen from the atmosphere and turn it into forms useable by plants
Why are bacteria capable of evolving more quickly than humans?
Because bacteria are less intelligent and therefore need to evolve more
Because bacteria undergo sexual reproduction more often than humans.
Because they are more primitive and have been on Earth longer
Because bacteria have very short generation times compared to humans
Because bacteria have very short generation times compared to humans

Which of these protozoans is an autotroph that can be good and bad? On the good hand they supply us with oxygen, on the bad hand they can cause toxic red tides in the ocean.
Trichomonas vaginalis
Trypanosoma
Dinoflagellates
Giardia intestinalis
Dinoflagellates
