  A scientist is attempting to engineer the secreted form of IgM from the transmembrane IgM shown in the schematic. Based on the structure of the μ heavy‑chain gene and its alternative splicing patterns, what specific modifications should be incorporated into the spliced mRNA variant to ensure production of a secreted IgM rather than a membrane‑bound form?

While assessing a patient, the nurse notes severe edema of the hands and feet from third spacing. The patient is having signs and symptoms of intravascular dehydration, and the total protein laboratory result is 4.6 g/dL (normal value is 6.0 to 8.3 g/dL). The nurse anticipates the health care provider will prescribe which IV solution for this patient?

* Questions 29-31 are based on the following: The main visitor attraction at Assateague Island National Seashore, other than the ocean and beaches, is a herd of wild horses (pictured above).  The horses are very acclimated to humans—they are often found blocking traffic and looking for handouts.  Another unique feature of the island is that it is home to what most people call “Sika deer,” which are actually more closely related to elk than to deer.  They stand about waist high and look a lot like young White-tailed deer. The horses were put on the Island by local farmers who were trying to avoid paying taxes on their livestock.  Over the years, horses escaped and formed a herd, and they have become the leading tourist attraction at the park.  The Sika deer were most likely brought to the island years ago by the Boy Scouts as part of some sort of agricultural project. As time has progressed, both species have had negative impacts on the relatively fragile barrier island ecosystem, causing increased erosion, the depletion of dune grasses, and numerous other problems.  In response to this, the National Park Service has pursued two different methods of population control: it allows hunting of the Sika deer, and uses fertility drugs to regulate the population of the horses.

* Questions 27-28 are based on the following statement made by Peter Singer, in reference to the idea of hunting wild animals to reduce their population sizes: “If it is true that in special circumstances [an animal] population grows to such an extent that they damage their own environment and the prospects of their own survival…then it may be right for humans to take some supervisory action; but obviously if we consider the interests of the animals, this action will not be to allow hunters to kill some animals…but rather to reduce the fertility of the animals. …[I]t would not be difficult to come up with something better than what is done now.” (Animal Liberation p. 234.)

* Questions 32-34 are based on the following: “Drive-through” trees are redwood trees with holes cut in their trunks large enough for cars to pass through.  This is done because people find it entertaining to drive through these incredibly large members of the plant kingdom.  Though there are still drive-through trees on private property in the pacific northwestern US, the National Park Service no longer operates any of these trees within national park boundaries.
