Ecology students are required to do a lab research project, and two students decide to study the population growth of beetles in a sack of flour (food for the beetles). They collect the following data: week 0 , 2,4,6,8,10,12 beetles 2,80,225,275,950,1100,1100,900 Identify the independent variable Identify the dependent variable

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.
