True because the surface of the water table may vary due to seasonal change
DNA/fingerprints are all unique, therefor it is easy to match a fingerprint to a person thus they use this mechanism in criminal investigations because only one person woul have matching DNA to the prints on the scene, and that is the criminal.
Hope this helps :)
<span>In nuclear physics, nuclear fusion is a nuclear reaction in which two or more atomic nuclei come very close and then collide at a very high speed and join to form a new nucleus. During this process, matter is not conserved because some of the matter of the fusing nuclei is converted to photons (energy).</span>
We have to find the force of gravity of an object that has a mass of 20 kg and then to choose the correct answer. The formula for the force of gravity is: F = m * g, where m is the mass of an object and g is the acceleration of the gravity ( on Earth : g = 9.81 m/s^2 ). F = 20 kg * 9.81 m/s^2 = 196.2 N, or approximately 196 N. Answer: A. 196 N<span>.</span>
That is known as the process of Osmosis
