Lecture 1-2
Where would you look on a phylogenic tree for the most recent common answer?
What are nodes
The B in BIDE
What is the number of births between times 0 and 1
What are the four types of biotic factors?
What are: Predation/Competition/Parasitism/Mutualism
any foreign substance, usually a
protein, that stimulates the body’s immune system
What is an antigen
Plus/minus interactions between species
What is parasitism and herbivory
What is the process where DNA is transcribed into RNA which is translated into proteins?
What is the central dogma
When is a population growing?
What is lambda > 1?
How does adding K change the growth model?
What is becomes logistic growth
What does an enveloped virus have that a non-enveloped virus doesn't?
What is a phospholipid bilayer/membrane?
A group of species that live and interact within a given geographic area
What is a community
A testable, possible explanation for
some natural phenomenon
What is a hypothesis
The maximal?rate?of?increase?of?the?
population?for?a?given?set?of?abiotic?
conditions
What is Rmax
affects a population differently depending on its size
What is a density-dependent factor
The fraction of population protected by immunity
What is P
What can parasites alter?
What is host behavior?
Overarching explanations that explain broad patterns in nature, are based on evidence, have been tested in many ways, are well-supported, and allow scientists to make valid predictions
What is a theory
When reproduction is continuous how does the population grow?
What is exponential growth
Affects a population the same, regardless of its size
What is a density-independent factor
What are the 3 enzymes that an HIV virus uses to attack a host cell?
What are reverse transcriptase, integrase, and protease?
What are the two phases of the life cycle of toxoplasma gondii?
What are the sexual and asexual phases
What is it called when a hypothesis must make specific predictions that can be critically tested by experiments or observational studies
What are the four things that can change a population size?
What are births, deaths, immigrations, and emigrations
Intraspecific competition is the biotic factor that regulates the population at what value?
What is K/carrying capacity?
What cells does HIV directly attack?
What are Helper T cells and macrophages
What is the most species rich group of plants?
