Evolution
Evolution is referred to as this at the genetic level.
What is a change in the gene/allele frequencies.
In terms of populations, evolution is defined as this.
What is the change/adaptation of a species in a population over time based on the "fittest" organisms.
The formation of a new species as a result of evolution is commonly referred to as this.
What is speciation?
This is another name for the Earth.
What is Biosphere?
These were the two requirements that Darwin said were necessary for Natural Selection.
What are a limited amount of resources and overpopulation?
These two geologists gave us evidence that the Earth was actually much older than we had originally thought.
Who are Lyell and Hutton?
Lamarck theorized this.
What is that organisms would change based on how perfect they were trying to become and their use of physical features from generation to generation?
In a dihybrid cross, the phenotypic ratio of the offspring will always be this.
What is 9:3:3:1?
Two lizard species on neighboring islands show similar characteristics in how they avoid prey by camouflage. This is an example of (in terms of evidence for Evolution).
What is biogeography?
This is the result of natural selection on single-gene traits.
What is a change in allele frequency, and thus, a change in phenotype?
What is sympatric speciation?
This enzyme helps to unzip DNA during DNA replication.
What is DNA Helicase?
A population of fruit flies have enjoyed their time feasting on a banana crop in Costa Rica. Farmers, however, have developed a pesticide that targets only fruit flies without sacrificing the integrity of the fruit. As a result, there is a drastic drop in the population of fruit flies, this is an example of:
What is the Bottleneck Effect?
Two frogs of very similar species live in the same habitat but never mate. Closer examination of these frog species reveal that some of the frogs mate in the summer while others mate in the spring. This is an example of:
What is temporal isolation/mating time differences?
This is the evidence for evolution that relates development of organisms to one another.
What is comparative embryology?
How could a new species be formed on a molecular level?
What is a mutation?
This specific class of organic molecules is permeable to the cell membrane.
What are lipids?
This is a mechanism of speciation where two species continue to get further and further apart over time.
What is gradualism?
These are the three important points of evolution that Darwin made.
What are individuals don't evolve, natural selection works with heritable traits, and evolution does not have an end goal?
Artificial selection is said to be unsustainable over a long period of time because of this key characteristic.
What is a lack of genetic diversity/variation in the gene pool?
These are six types of obstacles that could keep preexisting species from interbreeding.
What are gametic incompatibility, behavioral isolation, mechanical incompatibility, hybrid breakdown, temporal isolation, and habitat isolation?
In a cell that has 30% glucose concentration in an environment with 10% glucose concentration, the cell would be considered ______ to the environment and water would move ____ the cell.
What is hypertonic; into?
