When looking at the fossil record, rocks that are the furthest underground (deepest) would have ___________ Carbon-14 than fossils found closer to the surface?
More
Less
The Same
Which term best fits the definition: "An organism's ability to survive and pass on its genetic material to offspring"?
Inheritance
Fitness
Adaptation
Selection
A population of birds live on an island where seeds are their primary food source. Birds with smaller beaks can eat small seeds more easily and birds with larger beaks can eat large seeds more easily. A fungus destroys the plants that make large seeds, leaving only the small seeds as food. What type of selection is most likely to occur?
Directional
Stabilizing
Disruptive
None of these
The 2 male beetles at left are competing for a nearby mate. This is an example of _____________.
Intrasexual Selection
Intersexual Selection
Mutualism
Genetic Drift
A group of minnows get separated from the original population due to increased currents in the body of water in which they live. The new population begins to survive and reproduce separately. This is an example of _________________.
The bottleneck effect
Gene flow
The founder effect
Non-random mating
According to Hardy Weinberg Equillibrium, if the dominant allele (p) accounts for 70% of the allele frequency, how much of the allele frequency is comprised of the recessive allele (q)?
70%
30%
50%
None of these
Nearby populations are __________ likely to have different species because of _____________ between the populations.
