You can use refraction which is the bending of light through a transparent material. Also the freezing and boiling points of water. One last one is the Cartesian five experiment, this shows the density of water. Hope this helped.
I looked it up and it should be D. Nerve cells :)
Some isotopes, however, decay slowly, and several of these are used as geologic clocks. Dating rocks by these radioactive timekeepers is simple in theory, but the laboratory procedures are complex. <span>All methods rely on the fact that certain elements (particularly uranium and potassium) contain a number of different isotopes whose half-life is exactly known and therefore the relative concentrations of these isotopes within a rock or mineral can measure the age.</span>
During the research Ambulocetus would be the first to consistently stay in water and Set over time they developed feet arms and <span>hands used to swim.</span>
Which organelle controls cellular activity comparable to the way the brain controls body activity? The cell membrane
