Answer:
1) intake of glucose molecules from the blood by specific transporters
2) high amount of glucose in the blood, sending signals toward the pancreas
3) binding of hormones with receptors on the liver
4) release of hormones from the receptors
5) synthesis of hormones by beta cells
Explanation:
During ingestion of the meal, insulin is produced in response to high blood glucose levels (concentration of glucose increases after digestion of food). Like other hormones, insulin performed its action through binding specific signals to specific receptors e.g, liver, muscle cells. The high glucose level in the blood send signals through hormones to liver, fat, and muscle cell receptors. These receptors release specific hormones to beta cells of the pancreas. In response to the signals from receptors, beta cells synthesize insulin to minimize glucose levels in the bloodstream.
Viruses reproduce by inserting their genetic code into the genetic code of a cell, from there, an active virus will copy itself over and over until that cell bursts, where the new viruses can repeat the process. Another type of virus inserts itself into the genetic code, but does not actively reproduce. It sits and waits for the cell to reproduce for it, by splitting in the way cells do.

I’m not sure of the rest give me a second. (I’ll add the rest in the comments section) But hope this helps! :)
Stem cell therapies are not new. Doctors have been performing bone marrow stem cell transplants for decades. But when scientists learned how to remove stem cells from human embryos in 1998, both excitement and controversy ensued.
The excitement was due to the huge potential these cells have in curing human disease. The controversy centered on the moral implications of destroying human embryos. Political leaders began to debate over how to regulate and fund research involving human embryonic stem (hES) cells.
Newer breakthroughs may bring this debate to an end. In 2006 scientists learned how to stimulate a patient's own cells to behave like embryonic stem cells. These cells are reducing the need for human embryos in research and opening up exciting new possibilities for stem cell therapies.
