Ecology
What is the competition exclusion principle?
What is the fact two similar species can not occupy the same niche at the same time indefinitely
This was one of Darwin's most famous ideas about how traits are passed down
What is Natural Selection
What id the difference between macroevolution and microevolution?
What is the fact microevolution is small scale and macroevolution is large scale
What are the 3 phylum we covered in Lophotrochozoa?
What are Platyhelminthes, Mollusca, and Annelida?
What is the function of a cnidocyte?
What is to hunt prey and move the cell around
Provide two ways prey evolved to avoid predators
What is Mimicry (Batesian, Mullerian), (more options available)
What were Darwin's 4 Natural Selection Observations?
What are Variation, Overproduction, Population Growth Limits, and Differential Reproductive Success
This selection favors both extremes
What is disruptive selection
Which lophotrochozoan phylum has an incomplete digestive system?
What is platyhelminthes
This phylum is the only one we covered that is diploblastic
What is Phylum Cnidaria
The Graylag goose rolling its egg is what kind of pattern?
What is fixed action pattern?
This process is what caused the Darwin finches to change their beak shape/size through generations so they could hunt different resources
What is Character Displacement
Describe the 2 of the 3 postzygotic barriers
What are:
Hybrid Sterility - Hybrid lives, but is sterile
Hybrid Inviability - Hybrid dies
Hybrid Breakdown - Each generation less and less sterile and viable
What are the classes of phylum mollusca, and name an example of each?
What are Gastropoda (Slugs/Snails), Bivalvia (Clams/Oysters), and Cephalopoda (Octopus/Squid)?
Name 3 key characteristics of Nematodes
What are they are sexually dimorphic, they are pseudocoelomates, they have a complete digestive tract, and they are elongated roundworms
You move away from the room that smells. What specific kind of movement is that?
What is negative chemotaxis
What is the difference between Darwin and Lamarck's ideas?
What is the fact Darwin believed the best traits evolved and were passed down generation to generation, while Lamarck thought traits could be developed inone's own lifetime
Describe Genetic Drift and Give 2 Examples
What is genetic drift is where gene frequency varies from one generation to another by chance events. Two examples are Bottleneck Effect and Founder Effect
Which phylum is Hirudinea in, and what animal does it house?
What is phylum Annelida and Leeches
What subphylum of Anthropoda are spiders in?
What is Chelicerata
This growth curve is where populations are limited by the carrying capacity
What is Indefinite Growth Curve/K Curve/S Curve
*NOT DARWIN RELATED*
What are the 3 kinds of coelom cavities an organism can have/be?
What are Acoelomate (No Coelom), Pseudocoelomate (False Coelom), and Coelomate (True Coelom)
Describe 2 kinds of Balanced Polymorphism
What are:
Frequency Dependent Selection - How common a trait is shows how successful it is
Heterozygote Advantage - Heterozygote has higher fitness than homozygote (i.e. sickle cell anemia & malaria)
Name all 4 Classes of Platyhelminthes
What are Turbellaria, Trematoda, Monogenea, and Cestoda
Name the 4 Classes of Cnidarians
What are Hydrozoa, Scyphozoa, Anthozoa, and Cubozoa
