Experiment 1: Observation of Mitosis in a Plant Cell
In this experiment, you will look at the different stage of mitosis in an onion cell.
Remember that mitosis occupies only one to two hours of the cell cycle, whereas
interphase can take anywhere from 18
What are the major tools biologists use to study the history of life?
Phylogenies and fossil record.
Rapid morphological and ecological diversification of animals that occurred.
Major pattern in the
Lesson 6 & 7 Notes
Descent with modification, the species existing today have pre-existing
species and organisms have changed over time.
What did Darwin's natural selection do?
Provided a mechanism for how evolution occur by beak diversity in fi
How does speciation occur?
When populations of the same species become genetically isolated by lack
of gene flow and then diverge from each other due to selection, genetic drift,
What is a species?
Reproductively isolated fro
Lesson 4 & 5
adjacent populations exchange genetic materials but gene flow between
distant populations occurs only through intermediary populations.
How does speciation occur?
Reproductive Isolating Mechanisms
LECTURE 2 Notes
What did the rise of oxygen do?
Accelerated the evolution of eukaryotic cells and serial endosymbiosis.
What is endosymbiosis?
Anaerobic eukaryotic cell engulfed an aerobic bacterium that lost many
genes so it couldn't reproduce but eukary
