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.
Answer:Red is Dominate white is Submissive
Explanation: because the first generation had majority Red but were able to produce White in the second generation white has to be submissive
anaerobic and does not require oxygen
Answer: These external agents of genetic change are called mutagens. Exposure to mutagens often causes alterations in the molecular structure of nucleotides, ultimately causing substitutions, insertions, and deletions in the DNA sequence.
Explanation: Point mutations are a large category of mutations that describe a change in single nucleotide of DNA, such that that nucleotide is switched for another nucleotide, or that nucleotide is deleted, or a single nucleotide is inserted into the DNA that causes that DNA to be different from the normal or wild type gene
