Homo erectus -- One Species or Multiple Species?: Some hypothesize that Homo erectus should be subdivided into multiple species, others support a single species hypothesis with a broad geographic distribution and population variation. There is support for both hypotheses!!! Which hypothesis do you support? and why? What evidence would cause you to shift your support to the other hypothesis? and why? For your answers, paleontological details (geography, diagnostic traits, geologic dates) count!

Birds migrate from areas of low or decreasing resources to those with high or increasing resources of food and nesting locations. Long distance migratory birds would travel in the most energy-efficient way and would migrate only if they can further optimize their energy budget. The ability to maintain a high and constant body temperature enables birds to exploit a remarkable range of habitats. Discuss how behavioral and physical adaptation could help the migratory birds manage their body thermoregulation with minimal energy consumption. [Total : 20 marks]

What is a goal of human therapeutic cloning?

to transfer cells from an unrelated individual into a patient needing a transplant

to create pluripotent cells for medical research only

to make a new individual, who is genetically identical to a patient needing a transplant

to create pluripotent stem cells using a patient’s nucleus

to extract ES cells from an embryo

Please summarize the function of RNA polymerase II carboxy-terminal domain (CTD) in RNA processing for proper mRNA function

Acyl-CoA dehydrogenase deficiencies are diseases related to the impaired ability to oxidize fatty acids via beta oxidation. Symptoms of these acyl-CoA dehydrogenase deficiencies include hypoketosis [low blood levels of ketone bodies], hypoglycemia [low blood glucose], and hyperammonemia [increased blood levels of ammonia] during long periods of fasting.

a.) Please explain why patients with acyl-coA dehydrogenase deficiencies have bouts of hypogycemia  [1- 2 sentences is sufficient].

b.) Please explain why patients with acyl-coA dehydrogenase deficiencies have bouts of hyperammonemia [1- 2 sentences is sufficient].

40. Titanium, a hapten, is now being used frequently in human joint replacement. In terms of an immune response to titanium, you would expect

     a.   an innate immune response.

     b.   no immune response because titanium is not a large enough, complex molecule.

     c.   an allergic response because titanium is a metal

     d. no immune response because titanium is not part of any microorganisms

     e.   an adaptive immune response because titanium is foreign to the body.

41. Which of the following best characterizes antigens?

     a. Antigens may be proteins, polysaccharides, glycolipids, or glycoproteins that stimulate an immune response.

      b. Antigens come only from foreign microorganisms.

      c. Antigens are proteins called antibodies.

      d. Antigens are immunoglobulins the body produces in response to exposure to foreign

            organisms.

      e.   Both A and C

22.   Mrs. Jones titer shows high level antibodies but she has never had Chagus disease. Mrs. Jones is scared, although she has had no sign of illness, even after being exposed to this contagious disease. She is exhibiting:  

a.         natural acquired active immunity.

b.         natural acquired passive immunity.

c.         an allergic reaction.

d.         innate immunity.

            e.         artificial acquired passive immunity.

18. All of the following are benefits of fever, EXCEPT:

        a.   mobilizes defenses by promoting chemotaxis

        b.   inhibit bacterial growth and reproduction

        c.   catalyses metabolic reactions

        d.    increase metabolic rates

        e.   accelerates tissue repair
