There are several properties of water that make Earth a suitable environment for life, including water's high boiling point and high heat capacity. Which best explains why this characteristic of water is important for marine life? A)It allows water to remain in its liquid form even
relatively high temperatures.

B)It allows water to vaporize easily, powering the water cycle.

C)It allows water to be denser, making it easy for living organisms to move through

D)It allows water to resist freezing and thawing cycle

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.

Which of these is true for bacteria because they are prokaryotic cells? a. they can engulf body cells in order to make memory cells. b. they must invade viruses in order to reproduce. c. they are much larger than eukaryotic body cells. d. they can reproduce on their own outside of other cells.
