I believe the answer is A
Answer:
This question lacks options, the complete question is: What do you think would have the greatest effect on the body—a harmful mutation in a pluripotent embryonic stem cell, or a harmful mutation in an adult multipotent stem cell?The correct answer is a harmful mutation in a pluripotent embryonic stem cell.
Explanation:
Pluripotent Stem Cells can self-renew and differentiate into any of the three germ layers, which are: the ectoderm, the endoderm and the mesoderm. These three germ layers subsequently differentiate to form all the tissues and organs within a human being. If during embryonic development, genetic mutations - alterations in genes - occur in the embryonic stem cell, they pass to daughter cells as a consequence of cell division, and an individual is generated whose cells differ at the genetic level. Multipotent stem cells are organospecific cells, that is, they can give rise to any type of cells but from a specific organ (a lung, a kidney or the brain). Their differentiation ends the moment they specialize and become a cell with a specific function within a specific tissue or organ. If there were a mutation in these cells, it would damage a specific designed tissue or organ.
Answer:
Stimulus
Explanation:
The answer is stimulus. In plural it would be stimuli.
Vertebrates have a bilateral symmetry due to which their entire body is divided into right and left halves while the invertebrates either have radial symmetry or the bilateral symmetry. Therefore, option D is correct.
The other basic differences between the vertebrates and the invertebrates are that vertebrates have a spinal cord and a backbone while invertebrates lack them, vertebrates have well developed brain, lungs or gills in respiratory system and closed circulatory system.
Answer:
DNA replication is the process by that DNA make a copy to the cell division.
Explanation:
- DNA replication is the double structure to the DNA molecule,it is biological process.
- DNA replication molecule the serve that template for the production to referred conservative replication.
- DNA replication occurs living the biological property of division and they performed complementary stand.
- DNA replication to that begin the specific location and origins in the genome, and growing from the origin.
- DNA replication is performed to the outside and artificially to the cell,in the DNA molecule.
- DNA replication is single strand by the DNA chain of nucleotide function, DNA contain the sugar .
- DNA replication is the basis of single strand to 3 prime and 5 prime end, these refer to the carbon atom in the chain attaches.
- DNA replication allow the strand to the one another strand to used in partner strand.
- DNA replication is to matched in the template strand at one time with the creation of bonds,they high energy bonds.
