Identifying the elements of hypothesis-based science this experiment is an example of hypothesis-based science. what question did the researchers ask? what question did the researchers ask? can predation result in selection for color patterns in guppies? do female guppies prefer to mate with males with bright color patterns or drab colors? do male guppies in pools with pike-cichlid fish have brighter color patterns than females in the pool? do killifish prefer to prey on juvenile guppies or adult guppies?

Describe the function of the endomembrane system? what organelles are involved?

Subduction zones form when an oceanic plate collides with another oceanic plate or continental plate. the continental crust is lighter and less dense than oceanic crust. continental crust's density is approximately 2.7 grams per cubic centimeter. oceanic crust is thinner and the average density is about 3.3 cubic centimeters. when the two crustal plates converge the oceanic plate always bends and subducts beneath a continental plate. once the oceanic crust subjects, the rocks are subjected to changes in heat and pressure. because of this, we would expect to find rocks in the area of a subduction. a) clastic b) igneous c) metamorphic d) sedimentary
