the data cable below gives estimates for two populations in a candra ecosystem. polar bears are predators,
and arctic seals are their main prey.

recall from lesson 21 that only a small part of the energy in 2017 organism is passed to the organism that feeds on it. as a result, a prey population is almost always much larger than the predator population. one way to graph a predator/prey relationship is co label the left vertical axis with a scale for one population and the right vertical axis with a scale for the other.
use the data cable above to construct a line graph of the seal and bear populations over 10 years. make your graph on a separate piece of graph paper. label your axes, and include a key to distinguisha the
populations shown
question: what is the approximate size range for each population?

Match the following terms describing electrical events with the correct phases of the cardiac cycle. the ventricular muscle cells depolarize at the start of this phase. during this phase, na+ entry through the funny channels causes the pacemaker potential of sa nodal cells to gradually become less negative until it reaches threshold. the ventricular muscle cells repolarize right before this phase. the cytosolic concentration of calcium in the contractile cells of the ventricle is highest during this phase. a. isovolumetric relaxation b. ventricular ejection c. isovolumetric contraction d. ventricular filling
