The correct answer is self-renewal.
The hemopoietic stem cells, found in the red bone marrow, is a usual example of adults stem cells. These stem cells, divide into different kind of blood cells. The bone marrow also comprises a second kind of adult stem cell called mesenchymal or stromal stem cell. The adult stem cells have also been witnessed in various other kinds of tissues like skeletal muscle, brain, skin, blood vessels, heart, and the teeth.
These adult stem cells possess the tendency to differentiate into other kinds of cells, and can also differentiate in self-renewal to generate more of the similar kind of stem cells.
Self-renewal refers to the procedure by which the differentiation of stem cells takes place to produce more stem cells, continuing the pool of stem cells all through the life. Self-renewal is considered as the differentiation with the sustenance of the undifferentiated state.
Pair-bonding in a population of prairie voles can be prevented by . B) administering a drug that inhibits the brain receptor for vasopressin in the central nervous system (CNS) of males
<h3>
what is pair bonding?</h3>
Pair bonding is an evolutionary feature that may be important for reproduction as well as individual and species survival.
The proximate processes underlying many types of good social behaviours, such as pair bonding and maternal-infant behaviour, are shared by brain and endocrine systems.
The brain systems that rely on peptides, such as oxytocin, vasopressin, opioids, CRH, and associated hormones, are at the heart of pair bonding.
Neuropeptides also help to integrate the autonomic and endocrine effects of pleasant social encounters with behavioural states that promote social bond creation and maintenance.

Answer:
a) because after the cleavage of the phosphate groups, the phosphate at the 5´carbon atom is ready to bind the oxigen from the OH- in 3´carbon en the incoming nucleotide
b) The DNA ligase will need an energy source because after removing the RNA, the 5´carbon will not have the three phosphates to be cleaved so that the energy of those unions can be used to catalize the new union
