What is unique about stem cells?(1 point) They are only found in plants.

They are unspecialized.

They are differentiated.

They are only found in embryos.

The answer is that they are unspecialized.

Explanation:

Stem cells can turn into multiple different cell types, therefore they have no specific cell that they will become. They are unique because they can turn into many different cells. (Example being one turning into a tissue cell while another turns into a cell for the lungs)

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

the wetland preservation movement began in the u.s. in earnest with the clean water act (cwa) of 1972. although not specifically written to protect wetlands, the cwa is comprised of a series of regulations designed to prevent pollutants from contaminating u.s. waters.
