Answer:
<u><em>C. DNA from the S bacteria is necessary for bacterial transformation to occur.</em></u>
Explanation:
These series of experiments determined that DNA is the genetic material which gives rise to a particular type of cell. As we can see, the S bacteria with degraded proteins were able to grow when the proteins and RNA were degraded. But they were not able to grow when their DNA was degraded. This experiment proved that proteins or RNA are not the genetic material, rather DNA is the material related to inheritance.
I think it'd be B.. I might be wrong tho..
B. 245 million
from the end of Carboniferous Period to the beginning of the Triassic period
Answer:
See the answer below.
Explanation:
<em>Let the allele for eye color be represented by A. Blue is dominant over brown eye color, hence, blue allele would be A while brown eye allele would be a.</em>
Two parents have the genotype blue/brown which is equivalent to Aa.
Aa x Aa
AA 2Aa aa
blue eyes blue eyes brown eyes
a. Different possible outcomes: AA blue eyes, Aa blue eyes, and aa brown eyes.
b. Probability of a child from the cross having brown/brown (aa) genotype = 1/4 or 25%
c. Probability that the child would have blue eye color = 3/4 or 75%
