The intensity or refraction depends on the material
Explanation:
In the experiment, the purpose it to determine the effect of the material on the refraction index. The refraction index is the ration of the incident ray to the refracted ray. This relationship is known as Snell's law of refraction
where i and r are angles of incident an the refracted ray and n is the refractive index. The dense the material, the more the angle bends. This means that the angle of refraction, as measured by the protractor, is going to be large.
1.) It's best to have two pair of eyes for an experiment. Meaning one person to watch the chemicals while you're writing things down - especially if they're dangerous if mixed together. Basically it's best to take turns!
2.) They may have different results than you if you're in a lab - and it's always best to work together to get the job done! You can get the job done faster and more effectively if you work together! (:
I hope all is well, and you pass! Good luck, rockstar!
Answer:
they attach to the bones.
Answer:
B) Available energy decreases as trophic levels increase.
Explanation:
Each time an organism consumes energy, it absorbs it. When it dies the energy is released and only some of it is consumed the organism that eats the first organism. This continues and by the end there is very little energy left because most of it was released into the world.
