In a series of experiments, Avery treated heat-killed nonvirulent s bacteria with enzymes that degraded the proteins, dna, and r

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.

If a boy exhibits a sex-linked trait that is carried on the X chromosome, what must be true?
ad-work [718]

Answer;

C. His mother carried at least one allele for that trait

Explanation;

-Men have a single allele of each gene on the X chromosome, inherited from their mother, and a single allele of each gene on the Y chromosome, from their father.

-A sex-linked trait is a trait that is controlled by a gene or an allele located on the sex chromosome.

-X-linked traits are maternally inherited from carrier mothers or from an affected father. Each son born to a carrier mother has a 50% probability of inheriting the X-chromosome carrying the mutant allele.

The graph below represents the solar intensity measured over one day in northern Canada. What is the most likely date?
Dmitry [639]
It is important to note that the graph has 0 solar intensity for a long part of the day; around 16 hours. Only from 8 to 16 hours do we have significant sunlight.
This means that the length of day is very short during this time of the year;

The length of the day changes throughout they year; day is equal to night (12 hours each) during the solstices on March 21 and September 23 but during summer day is longer than night in the northern hemisphere; during winter it is smaller. THe smallest daylength is at December 21st (in the northern Hemisphere). This phenomenon is due to the tilt of the axis of the earth.

The correct answer is December 21; (if we talked about a place in the southern hemisphere, the answer would be March 21).
