Answer:

The correct answer is option A.

Explanation:

If a particular woman is a carrier (XhXH) for a sex-linked disease that means she has one copy of the recessive gene on X-chromosome(Xh) and one copy of the dominant gene on X- chromosome (XH).

For a male offspring of a carrier mother to not get affected by a sex-linked disorder there are 50 percent chances if his father is not affected. In this case, Male offspring receive an X chromosome only from mother. So it could be Xh or XH so this offspring has a 50% chance of being affected or unaffected.

Thus, the correct answer is option A.

larisa86 [58]

Answer:

The correct answer is - transformation.

Explanation:

Griffith's experiment was performed by Fredrick Griffith with Streptococcus pneumoniae. Streptococcus P. are rough non encapsulated streptococci that are converted into smooth encapsulated streptococci bacteria in presence of heat-killed smooth encapsulated bacteria.

This experiment was the first experiment that showed that this bacteria can get DNA by the process of transformation.

He suggested that the nonencapsulated bacteria had been transformed into the encapsulated smooth bacteria strain by the transformation process that was somehow part of the dead encapsulated strain bacteria.

Thus, the correct answer - transformation.

Which characteristic of viruses prevents them from being used as evidence to support cell theory?
Ne4ueva [31]

Answer:

Viruses replicate only inside host cells.

Explanation:

<u>Viruses are not used as evidence to support the cell theory because they are not considered a cell and cannot carry out vital life processes without getting into host cells. </u>

According to the cell theory, the cell is the basic unit of life, all living organisms are made up of cells and cells arose from preexisting cells. A virus that is not in a host cell is just a piece of DNA/RNA surrounded by a protein coat and is not capable of carrying out any life process for it to be considered living.

<em>Viruses are only able to reproduce and multiply when they get access to a living host. They use the genetic mechanisms of the host to replicate their DNA/RNA using the lytic or lysogenic cycle. Hence, they are not used to support the cell theory. </em>
