Scientific Method
This was the dependent variable used for the bean beetle and bean type/oil experiment.
What is # of eggs laid?
This was the temperature that the bacteria grew at overnight.
What is 37 degree Celsius?
This equation measures the genotypic frequency of a population in Hardy-Weinberg Equilibrium.
What is p^2 +2pq + q^2=1?
The type of microscope used to find Paramecium.
What is the light compound microscope?
Planaria demonstrated this type of taxis in the animal behavior lab.
What is negative phototaxis?
This was the independent variable used for the LC50 and Daphnia experiment in the ecology lab.
What is pesticide concentration?
This antibiotic was used in the lab report and inhibits bacterial growth via cell wall inhibition.
What is vancomycin?
These are the 5 assumptions for a population to be in Hardy-Weinberg equilibrium.
What are: No mutation, Random mating, No gene flow, Very large population size, and No natural selection?
The type of microscope used to count beetles eggs laid on beans.
What is the dissecting/stereoscope?
These are the 5 ecological levels of organization.
What are organism, population, community, ecosystem, and biosphere?
This was the negative control treatment for the bean beetle and sunflower oil experiment.
What are beans without oil?
In times of extreme nutrient deprivation, some bacteria can produce these.
What are endospores?
When comparing a similar region of DNA to species A, you counted the following differences:
species B: 4 differences
species C: 3 differences
species D: 7 differences
So, this species diverged last (based on the molecular clock hypothesis).
What is species D?
Gram-stained microscope slides should be disposed in this container.
This amount of energy generally transfers to the next trophic level.
What is 10%?
Name 2 controlled variables for the bean beetle experiment.
What are same number of beans, beetles, egg laying time, etc?
This was the dye/reagent that stained gram-negative bacteria pink.
What is safranin?
DAILY DOUBLE
This was the evolutionary factor represented by in the predator-prey (chopsticks-bean) experiment.
What is natural selection?
DAILY DOUBLE
This type of microscope slide was pre-stained, contains non-living specimens, and should be reused.
What is a prepared slide?
An example of this type of survivorship curve would be humans.
What is Type 1?
The minimum number of trials/replicates usually used during experiments to ensure accurate data.
What are 3?
These are the 2 differences between gram-negative and gram-positive bacteria.
What are thickness of the peptidoglycan and the presence of a polysaccharide outer layer?
This type of natural selection favors one extreme form of a trait.
What is directional?
Oil should be added on top of this to improve vision and protect the lenses.
What is a cover slip?
This type of pyramid shows the number of individuals within a trophic level
What is a pyramid of numbers
