33.) Salmon are known as ______; that is they are born in fresh water, mature in salt-water, and return to fresh-water to breed. Some eels are ______; being they are born in salt-water, mature in fresh-water, and return to the sea to breed.
34.) Neurons can be divided into 3 classes: ______, ______, and ______.
35.) ______is a form of asexual reproduction where the egg develops into a new individual without being fertilized.
36.) ______vision produces a broad overlap of fields of vision that allows for more depth perception (think predators). ______vision provides a wide field of vision but with less depth perception.

44.) A ______is a site where signals are transmitted from one cell to another (junction sites)—these can be electrical or chemical.
45.) ______coloration is a form of structural coloration where some wavelengths are reflected well and some are not. This causes apparent changes in coloration as the view of the organism changes

70.) Interspecific competition can result in a number of possible outcomes at the ecological level. In class we discussed several possibilities. Three of these outcomes were means by which competition was reduced among competitors (allowing coexistence), and one was the ‘ultimate’ outcome of extended competition between species. Name these three outcomes, briefly describe them, and provide an example of each.

75.) According to optimal foraging theory, a longer travel time to a patch will result in a longer time spent in the patch. Conversely, a shorter travel time to a patch may result in a short stay. Why is this the case? For both scenarios draw a graph containing energy gain lines for both a short trip and a long trip to the patch to show these relationships.
