What are stem cells? Where are they found?
Debora [2.8K]
Following the treatment, the Fetal Stem Cells will travel throughout the body, detecting damaged cells and tissue and attempts to restore them. The Fetal Stem Cells can also stimulate existing normal cells and tissues to operate at a higher level of function, boosting the body’s own repair mechanisms to aid in the healing process. These highly adaptive cells then remain in the body, continually locating and repairing any damage they encounter.

lbvjy [14]

Answer:

  t(n) = 3·5^(n-1)

Explanation:

icang [17]
You did not included your list of selections.  Some general properties ascribed to DNA are storage and expression of information and variables through mutations.  Replication, Transcription, Translation and Mutagenesis are the major functions of DNA in a cell.  DNA nucleotides contain deoxyribose.  DNA is double-stranded in the conservative mode, the original double Helix remains a complete unit and the new DNA double Helix is produced as a single unit.  In the double=stranded DNA, Hydrogen bonds hold one complimentary strand to the other.  

Hope this helps, I love Science.
