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.

You have cloned a gene for an enzyme that degrades lipids in a bacterium that normally lives in cold temps. you wish to use this
GaryK [48]
A) You would have to incorporate that gene into the bacteria's plasmid (genetic information that isn't in its main genome) so that it can use it and express its message. This is done using enzymes that cut that circular plasmid, insert the gene you want, and put the circular molecule back together. Once you have the bacteria with the plasmid in it, you replicate that bacteria, so all the resulting copies will have that gene and they'll express it.

B) If not enough protein is being produced it could be because you don't have enough bacteria, you'd need a bigger population. The medium the bacteria is in also should be optimal so that it can be as efficient as possible.

How is the age distribution pattern of the Hawaiian Islands - Emperor Seamount chain explained by the position of the Hawaiian h
levacccp [35]

Answer:

Find the explanation below.

Explanation:

The Hawaiian Islands is a series of islands positioned in what looks like a chain, which increases in age as one moves northwest. The Hawaiian hotspot was formed as a result of the collision of the tectonic plates in the outer part of the earth which caused the rise of a volcano, and which in turn gave off magma which came to rest on a seafloor. That eruption on the seafloor is the hotspot.

This hotspot remains unmovable while the tectonic plates are in constant motion around the hotspot, giving rise to further Islands. This explains the age distribution pattern of the Hawaiian islands which arrived at different times making some older than the others.
