Which browser is required to use Honorlock for your exam?

Louis de Broglie proposed that all matter has a dual nature. The wavelength of any particle is related to its momentum by this equation: Which of these is the best explanation of why we don’t notice wave behavior in large objects like baseballs, but it is fairly easily detected in small objects like electrons?

In the first half of the 1900s, the Bohr model was abandoned in favor of the quantum mechanical (wave) model of the atom. The next two questions test your understanding of the quantum mechanical model of the atom.

In an early experiment that helped determine the nature of atoms, gas was enclosed in a long, narrow glass tube. A metal plate near one end of the tube was given a large positive charge, and a plate at the other end was given a large negative charge. The particles that collected at each end of the tube were studied. Thomson’s plum pudding model was developed as a result of these experiments. What was discovered about atoms as a result of these experiments?

If microwaves were used instead of visible or UV light, what would be observed?

A “Jaglion” is the offspring between a male Jaguar and a female Lion. Jaglions have only been born in zoos and animal sanctuaries. Jaglions are able to live to adulthood. It is unknown whether Jaglions are able to produce viable, fertile offspring. If researchers find that Jaglions produce offspring that cannot reproduce, would you conclude that Jaguars and Lions are the same species or different species? Remember the definition of species that we discussed in class and in the pre-class video.

On average, out of 1000 DNA base pairs, how many are the same for two randomly chosen humans?

What do we mean when we say that populations of chimpanzees have five times as much variation as populations of humans?

If you were to find that all humans from Africa had allele 1, all humans from Europe had allele 2, and all humans from East Asia had allele 3 at a locus you are studying, what might you hypothesize about gene flow in human populations over the past 200,000 years (since humans started migrating out of Africa)?

  The two sets of pie charts above show two possible results from a study like the Rosenberg study that we examined in class. Both possibilities show possible results for the same locus. Colors show different alleles. For each statement, select whether possibility 1, possibility 2, neither possibility, or both possibilities support the statement. Options may be used more than once.   Prediction 1) There is more variation within geographic regions than between geographic regions. [blank1]   Prediction 2) There is more variation between geographic regions than within geographic regions. [blank2]   Prediction 3) It is possible to identify someone’s geographic origin based on their allele at this locus. [blank3]   Prediction 4) It is impossible to identify someone’s geographic origin based on their allele at this locus. [blank4]
