Evolution Assignment 1. You will research the following:

Fossils
Comparative Anatomy
Comparative Embryology
Biogeography
Molecular Biology
2. Your project should include descriptions of each as well as two examples.

3.You should present your research in a creative and detailed project. You may choose one of the following formats, or have another format approved by your instructor:

Slide-show presentation
Website
4. Be sure that your project:

is your own work and all text is written in your own words
includes citations of all resources used for your research
is presented in a way that is neat, organized, and clear
complete sentences should be used in all written descriptions and explanations

Choose the incorrect statement (a) the motor end plate membrane is only capable of generating graded potentials, but it is contiguous with the skeletal muscle sarcolemma, which can generate action potentials. (b) propagation of an action potential through the t-tubules into the sarcoplasmic reticulum triggers the release of ca++ into the cytoplasm of a skeletal muscle fiber. (c) the generation of suprathreshold endplate potentials in multiple muscle fibers could be due to the increased frequency of action potential generation at the axon hillock of a single motor neuron. (d) a greater amount of ach would be found in the presynaptic vesicles of a motor unit that fired several action potentials after exposure to botulinum toxin, than in a motor unit that fired several action potentials after exposure to the venom of the krait snake (which contains α-bungarotoxin).
