Question 22 (Essay Worth 3 points) (02.01 HC) A prediction of the theory of Plate Tectonics is that new volcanoes can form at th

Darina [25.2K]

Answer:

What would be the expected result of the experiment?

For the drawing of the map part, the scientific will find that effectively, a very large number of volcanoes are located near the meeting points of tectonic plates. The volcanoes that aren't now at the edge of the plate were most probably at the moment of their formation, and were moved away by the movement of the plate.

But I doubt the scientist would be able to identify many new volcanoes, because the creation of a volcano isn't something happening overnight.

How would you interpret the results if the scientist observes no new volcanic activity?

I would say that does NOT invalidate the theory because the observation period is extremely short. 10 years is an insignificant amount of time geologically speaking... the study would have to be conducted over at least 1,000 years to maybe have some results at all. Just imagine how many volcanoes there would be if a new one was created every 10 years along the side of a tectonic plate.

In cattle, RR = red, Rr = roan, and rr = white. What are the predicted color phenotypes for the offspring from crosses between:

timofeeve [1]

Answer:

a) 100% roan

b) 50% red, 50% roan

c) 50% roan, 25% red, 25% white

Explanation:

a) A red bull has the phenotype RR, a white cow has the phenotype rr. Let's do a punnett square. In its gametes, the bull only has R alleles to pass on, and the cow only has r alleles to pass on:

Bull

R R

r Rr Rr

Cow

r Rr Rr

The offspring can only be Rr, so all of them will be roan. (100% roan).

b) A red bull has the phenotype RR, a roan cow has the phenotype Rr. Let's do a punnett square. In its gametes, the bull only has R alleles to pass on, and the cow has an R allele and an r allele to pass on:

Bull

R R

R RR RR

Cow

r Rr Rr

50% of the offspring will be RR, and 50% will be Rr. So half of the offspring will be red, and half will be roan.

c) A roan bull has the phenotype Rr, a roan cow has the phenotype Rr. Let's do a punnett square. In its gametes, the bull has an R allele and an r allele to pass on, and the cow also has an R allele and an r allele to pass on:

Bull

R r

R RR Rr

Cow

r Rr rr

25% of the offspring will be RR, 50% will be Rr, and 25% will be rr. So half of the offspring will be roan, a quarter will be red, (RR), and a quarter will be white (rr)
