Wildlife can be scarce in many large, densely populated cities. A few plants and animals can be found in theseareas. For example, rats, mice, pigeons, cockroaches, and other insects are common in cities. Trees can grow by sidewalks or in local parks. Some cities even have small populations of coyotes within city limits.
Do you think these cities meet the definition of an ecosystem? Explain your reasoning.

Scientists designed an experiment to learn about the functioning of the hydrologic cycle and the phosphorus cyde
did not disturb the other plot. They were able to accurately measure the amount of water that flowed out of the
in a forest. Using two areas of the same size and geologic features, they cut all the trees down from one plot and
two plots as well as measure the amounts of phosphorus found in the runoff.
(a) Describe what the differences would be in the volume of water running off the two plots and give ONE
(b) Describe the differences in the levels of phosphate found in the runoff of the two plots. Assume that both
reason why. Assume that the two areas received the same amounts of precipitation.
(c) Describe ONE negative effect that might occur in a stream that receives the runoff water and sediment.
(d) When a tropical rain forest is cut down and used as farmland, the fertility of the soil only lasts a few years.
plots started off with the same amount of phosphorus in the soil.
Give an explanation as to why there is little organic matter in rain forest soil and what would happen to the
material after deforestation.

A female, tortoise-shell, tailless Manx cat mates with a male solid black tailless Manx cat. Their first litter produced 1 tailless tortoise-shell female, 1 tailless black female, 1 tailed black female, 1 tailless orange male, 1 tailless black male and 1 tailed orange male. In the second litter, they had 1 tailed tortoise-shell female, 2 tailless black females, 1 tailless black male, 1 tailless orange male, and 1 tailed black male.

A six-year-old Caucasian boy was seen by a maxillofacial surgeon to be evaluated for surgical repair of severe jaw misalignment. The boy was deemed an appropriate candidate for surgery at this time, with a second surgery planned during his teen years to complete the correction. The boy was adopted, and no family history was available. He had no personal history of excessive bleeding or bruising. The pre-surgical CBC results including platelet count were within reference ranges. Pre-surgical hemostasis testing is as follows: Ryan L.
