100
aceolamate, parasitic worm
platyhelminthes/ flat worm
100
similarity in sequence of a protein or nucleic acid between organisms of the same or different species. These can be used to infer relatedness.
homology
100
guard cells that open and close stomata
decrease loss of water due to evapotranspiration
100
What is the smallest unit of evolution?
a population
200
mosses/liverwarts, angiosperms, ferns, green algea
green algea, mosses, ferns, angiosperms
200
highly reduced ceolem, segmentation, filter feeder, shell secreted by mantle, muscular foot for attachment
bivalve
clam/scallop/mussel
mollusca
200
The separation or division of a group of organisms by a geographic barrier, such as a mountain or a body of water, resulting in differentiation of the original group into new varieties or species.
inverterbrate, bilaterally symetrical larvae, water vascular system, tube feet, deuterostome
echinoderm
300
association between organisms of two different species in which one is inhibited or destroyed and the other is unaffected
amensalism
300
1. Identification of species based on evolutionary relationship
2. Identification of a species based on reproductive isolation
1. phylogenetic species concept
2. Biological species concept
300
What kind of information is used to create a phylogenetic tree? What kind of information makes this process challenging?
mostly genetics
difficult to determine based on fossil evidence
difficult because of paraphyletic and polyphyletic groups
400
breakdown of proteins, nucleic acids, carbohydrates, fats
carbohydrates (mouth), proteins (stomach), nucleic acids and fats (small intestines)
all are completed in the large intestine except fat digestion which starts and finishes in the SI
400
terrestrial vertebrate that goes through metamorphosis adn has a three chambered heart
amphibian - frog
400
association between organisms of two different species in which one is inhibited or destroyed and the other is unaffected. similar to fertility
fecundity
400
Increased levels of capsaicin in berries
higher germination
mouse is selecting agent because it causes strong selection pressure on increased levels of capsaicin because berries without it do not germinate (so they do not pass on their genes)
400
List and describe a prezygotic barrier and a postzygotic barrier
Phylum: Chordata subphylum: vertebrata superclass:agnatha
lamprey
sounds a lot like it could be in chondrycthes too
500
Female frogs select their bate based on the length of the mating call, but these mating calls attract predators
Trade-off
(also think about survivorship curves)
500
Connections between the excretory system, the digestive system, and circulatory system
waste created by breaking down food is toxic, connecting the exretory system to the digestive system these makes the process of eliminating wastes more efficient. connections to the nervous system will bring nutrients through body as well as allow for the removal of toxins
500
What were the effects of the increase in atmospheric oxygen on the earth?
mass extinction wiped out obligate anaerobes
allowed for the formation of larger maromolecules
called oxygen revolution
