Evolution is sometimes defined as the change in ________ over time.
What is allele frequency?
The type of reaction that releases energy.
What is an exergonic reactions?
What is homozygous dominant?
These membrane-bound proteins act as channels for water molecules.
What are aquaporins?
This organelle.
What is the mitochondria?
Natural selection
Mutations
Gene flow
_______________
Non-random mating
What is genetic drift?
The first law of thermodynamics.
What is conservation of energy? What is energy not being created or destroyed?
1. Large population
2. No migration
3. __________
4. Natural Selection
5. Random mating
What is no mutation?
The type of solution that does this to your cells.
What is a hypertonic solution?
Proteins destined for shipment are created on the ribosomes of this organelle.
What is the rough ER?
Geographic isolation is this type of barrier.
What is a prezygotic barrier?
Pathways that build up molecules.
What are anabolic pathways?
You have sampled a population in which you know that the percentage of the homozygous recessive genotype (aa) is 36%. Using that 36%, calculate the frequency of the AA genotype.
What is 0.16 or 16%
The water potential of pure water in an open beaker.
What is 0?
This organelle contains digestive enzymes that aide in the breakdown of materials.
What is a lysosome?
Populations most affected by genetic drift.
What are small populations?
This molecule is used as key factor to energy coupling processes.
What is ATP/ADP?
A population of birds contains 16 animals with red tail feathers and 34 animals with blue tail feathers. Blue tail feathers are the dominant trait.What is the frequency of heterozygotes?
What is 0.49 or 49%?
The pressure that counteracts the diffusion of water into a plant cell.
What is turgor pressure?
Substrates attach to this part of the enzyme.
What is the active site?
A group that consists of all the evolutionary descendants of a common ancestor.
What is a clade?
The second law of thermodynamics states that this is increased over time.
What is entropy?
The ability to taste PTC is due to a single dominate allele "T". You sampled 215 individuals in a biology class, and determined that 150 could detect the bitter taste of PTC and 65 could not.What is the predicted frequency of dominant allele (T)?
What is 0.45 or 45%?
These membrane bound proteins transport hydrogen ions across the cell membrane in active transport.
What are proton pumps?
The site on an enzyme where noncompetitive inhibitors attach, thus changing the conformation of the enzyme and decreasing its activity.
What is the allosteric site?
