What evidence was found from soft tissue samples of a remarkable well-preserved tyrannosaurus rex that provided molecular evidence linking t.rex to a chicken? a. antibodies that react in a specific way with chicken proteins reacted in the same way with t. rex proteins. b. oxygen was found to be essential to t. rex’s survival in the same way that it is essential to a chicken’s survival. c. t. rex cell structure was found to be similar to the cell structure of chickens. d. t.rex cells were found to use glucose as a source of energy just like a chicken’s cells use glucose.

Review the graphs carefully. based on the information in figures 2.5 and 2.6, explain the relationships between led irradiance and carbon dioxide concentration over time for a chamber containing a water hyacinth. use the evidence from the graphs and your knowledge of science to support your answer. figure 2.5 shows the light intensity (led irradiance) over time for a chamber containing a water hyacinth. figure 2.6 shows the change in carbon dioxide concentration over time for a chamber containing a water hyacinth.
