A contractile vacuole works just the same as the name suggests, in that it expands and contracts. The point of the contractile vacuole is to pump water out of the cell through a process called osmoregulation, the regulation of osmotic pressure. It occurs in freshwater protists, but mainly in the kingdom Protista as a whole.
Single seismograph can register the occurrence of an earthquake. Analysis of the waves can yield the distance between the sensor and the epicenter. This describes a circle with the seismograph at the center. ... Adding data from a third station pinpoints the epicenter as the only place where all three circles intersect
D surface tension because, adhesion is sticking, b makes no sense for this question, and heat has nothing to do with it either, because it distributes it's weight throughout its legs so it doesn't sink (it doesn't weigh much so this works.)
Hope this helps don't forget to hit that heart :)
<span>The population dynamics of the Warbler species differ from what's documented by Scott Sillett and colleagues one migration issues.
The Warbler species are non migratory species, while Scott Sillet and colleagues have been studying migratory species. The Warbler species were even taken to other islands, in some cases, in order to give them the </span>security of additional breeding populations, this because their population dynamics is not a migratory one. The studied species by Scott Sillet and colleagues, on the other hand, have migratory population dynamics: they pass their Summer time in <span>New Hampshire and and their Winter time in Jamaica.</span>
I would say A) Coevolution because the two species would evolve in response to one another. Flowers and their pollinators must evolve together. For example, if the flower has a mutation that no longer attracts the bumblebees, it will not reproduce. Then the hummingbird would have to find a new food source.
