1. compare and contrast charging by contact, charging by
friction, and charging by induction.
2. the leaves of a metal leaf electroscope are slightly separated,
indicating that it is charged. when you bring a positively charged
rod near the sphere, the leaves spread farther apart. what charge
is on the electroscope? draw diagrams to explain your answer.

Examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. polyploidy is creating new species. the two populations are not interbreeding freely. hybrid offspring of the two populations begin to appear. one species will increase into a population size twice as large as the other species.
