A bear walks into the room. In response, you run away. Trace the events that occur from the initial release of epinephrine to the release of glucose into the blood to the generation of ATP (which ultimately leads to muscle contraction). In your answer explain the processes of a. epinephrine signal transduction leading to glucose release b. cellular respiration using glucose as the substrate and generating ATP c. acetyl choline signal transduction at the neuromuscular junction d. generation of the action potential e. muscle contraction that results

How is ribosomal rna useful as a molecular clock? a. a large portion of the dna ring is not vital to structure or function, allowing it to accumulate neutral mutations. b. its rate of mutation increases over time as organisms continue to evolve and differentiate from each other. c. a slow mutation rate makes it useful for determining evolutionary relationships between ancient species. d. it is only found in select organisms, making it easier to compare relationships between species that have it.
