Types of Isolation
Of the seven species of cicadae, three follow a 17-year mating cycle, while four follow a 13-year cycle. In regions where their geographic range overlaps, their emergence coincides once every 221 years. This last happened in North America in 2015 and will not occur again until 2236.
Temporal isolation.
A random process that occurs in nature.
Genetic Drift
The beaver in North America and the capybara in South America share a common ancestor but have evolved to look different.
Divergent Evolution
What is the function of the Plasma (Cell) Membrane?
BOUNS- What is the name of the transport that use ATP?
Regulate what enters or exits the Cell.
BOUNS ANSWER- Active Transport
What subject does Ms.Mitchell Teach
Biology
A type of isolation in which two populations are separated by a physical barrier, such as a canyon, river, or lake, preventing them from interbreeding.
Geographic isolation
A rancher raised a prize breeding bull and bred several of his female cows with him. Another rancher bought the bull and brought it to his ranch to replace the bull he had recently lost. He put the bull out to pasture with his cows.
Gene Flow
A kit fox lives in the desert and has large ears with greater surface area that keep the fox from overheated. The red fox lives in the forest and has a red coat that keeps it camouflaged.
Divergent Evolution
Name the two steps of Protein Synthesis.
Transcription and Translation
What are DNA and RNA made out of?
Deoxyribonucleic Acid and Ribonucleic Acid
In the Great Lakes region of North America, gray wolves and coyotes are similar but do not mate because their breeding periods occur at different times of the year
Temporal isolation
A population of Canadian geese traveling south flew through a storm. Two geese were blown off course and had to land for the night. The next day they heard another population of Canadian geese flying overhead and joined them in their migration.
Gene Flow
Hummingbirds have a beak just the right length to reach the nectar in cardinal flower and as they feed their foreheads bump into the pollen structure. Cardinal flowers are red which hummingbirds can see but bees can't. Cardinal flower's pollen structure is just the right length for the hummingbird to pick up pollen as it feeds.
Coevolution
What is a mutation.
A change in the DNA's nitrogenous base sequences during synthesis causing change to occur.
What are Prokaryotic Cells?
Tiny, single-celled organisms.
There is no true nucleus; there is a nucleoid region or area, but there is no nuclear envelope to surround or protect the genetic material (single circular chromosome)
No membrane-bound organelles
Free-floating DNA
The females of two species of fruit fly, Drosophila melanogaster and Drosophila simulans, release slightly different mating hormones called pheromones, which are used to attract mates.
Behavioral isolation
A pond containing round-tailed guppies, flat-tailed guppies, and pointed-tailed guppies began to dry up. After several weeks of no rain, the only guppies left were either round-tailed or pointed-tailed.
Natural Selection
Monarch butterfly eats poisonous milkweed to protect itself from predators. In return, the butterfly will transport pollen for the milkweed.
Coevolution
Name the three types of osmosis.
Hypertonic, Hypotonic, and Isotonic
What are living Living Characteristics?
Genetic material
Change over time (mutate/evolve)
Reproduce
A type of isolation in which two populations are separated by a physical barrier, such as a canyon, river, or lake, preventing them from interbreeding.
Geographic isolation
In cuttlefish, large males will protect females from other males to prevent them from mating. The small males, however, will mimic the color and shape of a female to swim under the large male and mate with the females, passing on their genes.
Natural Selection
Ostriches (Birds) and giraffes (Mammals) are both native to savannahs of Africs. They both share the same characteristic of a very long neck.
Convergent Evolution
Name most organelles in an animal cell. (At Least 8)
Nucleolus, nucleus, ribosome, vesicle, rough endoplasmic reticulum, smooth endoplasmic reticulum, Golgi apparatus, cytoskeleton, mitochondria, small vacuole cytosol, lysosome, centriole.
What is a Virus?
Non-Living
Not a cell
Needs a Host- living cells
Has DNA or RNA, not both
DNA held in Capsule
Uses projections to attach to host cell membrane
Can't metabolize without a host
