Answer: D - geographic isolation
Explanation:
1. The cells contain the same genes and express the same genes.
2. Multipotent (can differentiate to a limited number of cell fates/into a closely related family of cells).
3. Multipotent, totipotent, pluripotent (though I'm not 100% sure on this one).
4. Provide a source of cells for the body to replace certain types of cells that die.
That point is in southwestern Manitoba, Canada, about 125 miles
west of Winnipeg.
Note:
A latitude and longitude define a single point on Earth, so it's not possible
for a whole country to be located right there ... not even a very small country.
