The best way to do that is with animal kingdoms.
To protect the tree from harmful bugs, animals, or other predators.
Matter can change from one state to another when thermal energy is absorbed or released. A great example is Ice having its state changed to the liquid that is WATER. When ice is heated, it absorbs thermal energy and its temperature rises. At some point, the temperature stops rising and the ice begins to change to water, a liquid. As we all know, The change from the solid state to the liquid state is called melting.
Answer:
2. Alec Jeffreys
Explanation:
'DNA fingerprinting' or DNA typing (profiling) as it is now known, was first described in 1985 by an English geneticist named Alec Jeffreys. Dr. Jeffreys found that certain regions of DNA contained DNA sequences that were repeated over and over again next to each other.
Answer:
A more dense material will cause the light to bend more. (dense substances have a higher refractive index)
A less dense material will cause the light to bend less.
The speed of light decreases with more dense materials (the denser the material, the more slowly light travels through it.)
The speed of light increases with less dense materials.
