Answer:
If a light ray projected through a diamond, the light would refract snd it would act almost like a prism. It would make a rainbow, and the light would break up and disappear
Answer:
Translocation
Explanation:
Changes occur to the nuclear material from time to time. These changes are referred to as MUTATIONS. A mutation is a change in the nucleotide sequence of a gene. Mutations are of different types depending on how it occurs.
According to this question, the kind of mutation/abberation described is TRANSLOCATION. Translocation is a kind of chromosomal abnormality in which one segement of a chromosome containing certain genes breaks off and reattaches to a different chromosome.
This is the case in this question regarding the genetic composition of corns where genes for waxy and virescent kernel appearance occur in the same chromosome. It was found out that, in a stock of corn, these two genes are now on different chromosomes. This means that a segment of the chromosome containing one of the genes broke off and got reattached to a different chromosome. Hence, TRANSLOCATION MUTATION has occurred in this stock of corn.
a. Does putting the yeast on salt cause the beneficial mutation? Why or why not?
When the logarithmic growth of cells is interrupted by exposure to a 0.5 to 2 Molar salt solution the aueous solution consisting of KCl, NH4Cl, NaCl, MgCl2 are basically mutagenic in yeast .
Stationary phase cells are not mutated by the treatment.
b. If you screened your mutagenized yeast cell population on caffeine (another substance that normally kills them), could you find caffeine tolerant ones? (assume there is the potential for genetic resistance to caffeine).
For normal tolerance to caffiene the sty1 and pap 1 pathways are not necessary, but generally only sty1 is activated by mutation hence making yeast sensitive for caffiene.

I believe D but that's wrong it's definitely C

Answer:
It is the first ones, cannot support populations of species that require large areas. I think that is right.
