How can a water strider (aquatic insect) walk across the surface of the water? * a)adhesion b)capillary action c)specific heat d)surface tension

D surface tension because, adhesion is sticking, b makes no sense for this question, and heat has nothing to do with it either, because it distributes it's weight throughout its legs so it doesn't sink (it doesn't weigh much so this works.)

Hope this helps don't forget to hit that heart :)

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.
