Chapter 52
What level of ecology studies one type of organism in a given area?
Population
When are death rates high in a Type 3 survivorship curve?
Early in life
What kind of mutualism involves the other organism dying without its partner?
Obligate mutualism
Does blood dilate or constrict in response to heat?
Dilate
(Remember Arnold)
What is the functional unit of the kidney?
The nephron
What causes seasons?
Earth's tilt
Is iteroparity associated with R or K selected organisms?
K
Batesian
A sterile mule (the offspring of a donkey and a horse) is an example of what postzygotic barrier?
Reduced hybrid fertility
What are the other 2?
What are the prezygotic barriers?
What tissue connects bone to bone?
Ligaments
In the rainshadow effect, which side of the mountain gets rain?
Windward side
Which model of population growth represents a population that has/will reach a carrying capacity?
Logistic Growth
Poison dart frogs use what pattern of coloration?
Aposematic
(A-"poisom"-atic)
What comes first, the gastrula or the blastula?
Blastula!
Zygote-->Blastula-->Gastrula
What type of organism has a body cavity completely surrounded by mesoderm?
Colemates
(because psuedocoelmates are fake/two-faced: their coelom touches both the mesoderm and the endoderm)
What is the largest terrestrial biome?
Coniferous forest (Taiga)
Are birth rates higher in developed or underdeveloped countries?
Underdeveloped
What is it called when organisms share an ecosystem by occupying different niches?
Resource partitioning
What are the 5 requirements for Hardy-Weinberg equilibrium?
Large population
Random mating
No natural selection
No gene flow
No mutations
What event lead to cephalization?
What is a shallow aquatic zone with sufficient sunlight for plant growth? In this zone, light can shine through to the floor of the body of water.
Littoral Zone
(Photic zones aren't always in shallow water--photic zones are the top layer of any water, regardless of the total depth)
Name a method of estimating the density of a population (besides extrapolation from small sample/ taking index of population size)
Mark and recapture
Name the interaction between organisms in which one organism benefits without the other organism being in direct contact.
Facilitation
What is it called when a species splits because of a geographical barrier?
Allopatric speciation
What is the primary site of reabsorption in the nephron?
Proximal tubule
(It's the first one)
