In an experiment A scientist makes radioactively labeled probe using yeast DNA. She then discovers the probe hybridizes to a small segment of dna isolated from a fruit fly

satellites are frequently used to make observations of the orbit on earth

the fossil record provides evidence of a common ancestor to many species.

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.

above statement is not a true statement about the open ocean because the open ocean has low levels of nutrients. most of the photosynthetic activity on earth occurs in the open ocean within the photic zone. organisms in the deep ocean are exposed to frigid temperatures and total darkness but it does not begin at the low-tide mark.
