The answer is stem cells, they consist of classes of cells
that are undifferentiated and are able to be classified them into types like
specialized cells. They consist of having two main sources that will help them
develop and mature, these main sources are called the embryonic stem cell and
the adult stem cell.
Answer:
The correct answer is c.With an RNA virus, radioactive RNA would have been in the final pellet.
Explanation:
Hershey and Chase infected<em> E.coil</em> with bacteriophage which was having DNA as its genetic material. The bacteriophage was labeled with radioactive sulfur and radioactive phosphorus and it was radioactive phosphorus that was found in the bacterial cells or pellet.
As because DNA contains phosphorus, not protein therefore they it was proved that DNA is the genetic material. Similarly, RNA is also a nucleic acid which is genetic material for many viruses and contains phosphorus.
So if Hershey and chase might have chosen an RNA virus then radioactive RNA would have been present in the pellet. So the correct answer is c.
The chromosomes of offspring are not identical to those of their parents or siblings because <u>genetic information</u> is shuffled during meiosis.
Meiosis can be described as a cell division process by which gamete cells divide. The number of chromosomes is reduced to half in this cell division process.
During the process of meiosis, genetic information is shuffled between non-sister chromatids of the homologous chromosomes. This shuffling process is referred to as crossing over. A new combination of alleles is formed due to the process of crossing over.
It is due to the process of crossing over that the organisms produced are not identical to each other or the parents. Genetic diversity is important in order for populations to survive which is possible through the process of meiosis.

The father's father donates only the Y chromosome, not the X chromosome. The father's mother gives him his X chromosome.
Therefore, the father's father does not pass on any of the genetics of his X chromosome
