Today, it's widely accepted that all of the two-legged meat-eating dinosaurs known as theropods— including t. rex and albertosaurus—had at least very simple fuzzy feathers covering their bodies. according to the tree you built, what distinguishes the feathers of modern birds and archaeopteryx from the feathers of other theropods?

Plant species a has a diploid number of 12. plant species b has a diploid number of 16. a new species, c, arises as an allopolyploid from a and b. the diploid number for species c would probably be a) 12. b) 14. c) 16. d) 28. e) 56.

How would you describe an allele that be expressed and determines an organisms appearance? a.uncapitalized b.responsive c.recessive d.dominant

How do high-energy electrons from glycolysis and the krebs cycle contribute to the formation of atp from adp in the electron transport chain? a. high-energy electrons interact with pyruvic acid to create a phosphate bond with adp, forming atp. b. high-energy electrons supply the needed energy to synthesize atp from the lower-energy adp in the electron transport chain. c. high-energy electrons supply a negative charge which causes the citric acid to oxidize, forming a phosphate group to bond with adp. d. high-energy electrons increase the temperature of adp so it easily reacts to form atp.
