How do plants contribute to the water cycle?

Plants, especially trees, contribute to the water cycle via transpiration, where water evaporates from the surface of their leaves. Close to 10 percent of all water enters the water cycle due to plant transpiration. Animals contribute to the water cycle via respiration, perspiration and urination.

hope this helps :)

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.

her next move would be to use agarose gel electrophoresis to separate the dna molecules of varying length and create a dna fingerprint.
