What are facts about embryonic stem cell research?

All embryonic stem cells are undifferentiated cells that are unlike any specific adult cell.

Human embryonic stem cells are derived from in vitro fertilized embryos less than a week old

Embryonic stem cells are of great interest to medicine and science because of their ability to develop into virtually any other cell made by the human body.

Scientists have been attempting to isolate and culture human embryonic stem cells for more than a decade.

Human embryonic stem cells will offer insights into developmental events that cannot be studied directly in humans in utero or fully understood through the use of animal models

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.

explanation:

blue stars have the highest surface temp

stellar distances are usually expressed in light-years

the measure of a star's brightness is called magnitude

hope this !
