Bullock’s and Baltimore Orioles interbreed where their range overlaps, and hybrids are viable and fertile. However, hybrids also molt twice a year, unlike either parental species, which molts only once per year. Molting is energetically expensive. Additionally, a phylogenetic tree of oriole species is displayed below. Using two species concepts that we discussed in class, explain whether Bullock’s and Baltimore Orioles are the same species or different species. Be sure to name and briefly define the two species concepts you are using (they do not need to come to the same conclusion)

1. beginning with all chambers of the heart in the "relaxed" phase, describe the cardiac cycle in mammals, with systole and diastole of the atria and ventricles. for each time point in the cycle you select, state the following: • whether the atria and ventricles are contracting or relaxing • whether the av valves and semilunar valves are closed or open • whether the pressure in the atria and ventricles is high or low
