Cellular Energetics
A chemical agent that speeds up a reaction without being consumed by the reaction.
What is an enzyme or catalyst?
Fruit fly body cells have 8 chromosomes. After mitosis, you would expect a resulting fruit fly daughter cell to have
What is 8 chromosomes?
The flow of genetic information in cells from DNA to protein (Central Dogma).
What is DNA to RNA to protein?
Occurs from the interaction between the environment and the inherit variability in a population. Individuals best suited to their environment will pass down those favorable traits to their offspring.
What is natural selection?
Predation and disease are examples of which limiting factor.
What is density-dependent?
Factor that causes an enzyme to denature.
What is pH, substrate concentration, enzyme concentration, or temperature?
In this phase of the cell cycle, crossing over occurs.
What is prophase I of meiosis?
In eukaryotes, DNA is tightly wound around this protein.
What is a histone?
Genetic variation can arise from this random change in the DNA of a gene.
What is a mutation?
The percentage of energy passed between trophic levels.
What is 10 percent?
Autotrophs undergo photosynthesis or chemosynthesis. Name the products of photosynthesis.
What is glucose and oxygen?
The process when two neurons communicate through neurotransmitters.
What is synapse?
Part of a gene that does not code for a protein.
What is an intron?
A bird that can easily outcompete other birds for food and that can produce many eggs has a high ____.
What is fitness?
Species that has a high mortality rate, high number of offspring, and low parental care.
What is r-selected species?
This type of inhibitor bonds to the active site of an enzyme, preventing the enzyme from catalyzing the reaction.
What is a competitive inhibitor?
Long distance signaling in animal cells.
What is endocrine?
A protein that binds to the operator and blocks the RNA polymerase.
The more genetic variation a population has, the more likely it is for some individuals to ________.
What is survive?
A species that exerts a large, positive impaction on its ecosystem.
What is a keystone species?
This molecule acts as an electron and proton acceptor to carry energy to the electron transport chain in cellular respiration.
Molecules that bind to membrane receptors.
What are ligands?
Group of structural and regulating genes that function as a single unit.
What is an operon?
Two evolutionary forces that can introduce new genetic variation into a population.
What is mutation and gene flow?
At low densities and in the absence of any other beetle species, the population of a strain of the flour beetle Tribolium castaneum grows at a per capita rate of 0.3 per week. In controlled lab conditions, the per capita growth rate is reduced by 0.015 for every 100 individuals. The addition of a related beetle, Tribolium freemani, further reduces the per capita growth rate of T. castaneum by 0.02 for every 100 T. freemani individuals.
If there are 800 T. castaneum and 500 T. freemani individuals, what is the per capita growth rate of the T. castaneum population?
What is 0.08?
