An alpheid shrimp digs and maintains a deep burrow keeping it safe. Above ground, it is vulnerable to predators. A goby fish lives in the burrow with the
shrimp and sits at the entrance, keeping watch for predators. It signals the
shrimp with a flick of its tail when it is safe to come out; if a predator swims by,
the goby darts into the burrow and the shrimp retreats further inside. The goby
benefits by getting a burrow to live in and the shrimp knows when predators are
near. What type of relationship is this?

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.

The theories on the expansion of galaxies maybe re-examined to strengthen science should not be tested to strengthen science will weaken scientific knowledge if they change will become laws if they don't change
