Communication by the nervous system depends on the flow of information through chains of neurons that are functionally connected by synapses. The most common synapse in the human body is the chemical synapse.

1. Define chemical synapse. 3 points
2. Describe the chain of events that occur at a chemical synapse. (HINT: Your answer should begin with an action potential arriving at an axon terminal.) 5 points
3. What events account for the synaptic delay? 2 points
4. Give one example of a chemical synapse that we have discussed in BIOL 2120K. 3 points

A novel chimeric monoclonal antibody (Nocatmab) has been developed for the treatment of tetanospasmin toxicity, one of the most potent and dangerous toxins known in modern medicine. Each molecule of Nocatmab inactivates four molecules of tetanospasmin. Knowing that the lethal dose for tetanospasmin is 2.5 ng/kg for a human adult, and that the MW (Molecular Weight) of tetanospasmin is 150,020 amu, can you calculate the minimal dose of Nocatmab (MW 348,055 amu) required to treat a subject who weighs 63 kg and has recieved a lethal dose of tetanospasmin?

Economic laws have been true throughout human history. As an example, consider the following passage, from Professor Samaddar’s lectures on the economy of Ancient India:“Weaving in India has been encouraged from time immemorial... As is the case now-a-days, labourers working overtime were given extra payment... and special rewards were given for working on holidays.”

Using a supply and demand diagram in the market for labour, clearly explain why Indian workers working overtime or during holidays were paid extra.(15%)

Your organization, located in Manitoba, will be enhancing the group benefits plan offered to employees in two months by adding accidental death and dismemberment (AD&D) coverage and vision care coverage. The organization will pay 50% of the cost of the AD&D premiums and 50% of the cost of the vision care premiums, with the employees paying the other 50% of each premium. The Manager of Human Resources, Sophie Martin, has requested that you, as the Payroll Supervisor, prepare a communication for the employees, explaining how these new benefits will impact their net pay.

Public health emphasizes the importance of safe home, work, and community environments. Reliable access to clean drinking water, a toilet, and fuel is critical for human health. Minimizing exposure to hazards and injuries at work is is also essential for safety and well-being.

1. Describe how neoclassical and institutional economists approach the study of consumption. How do these approaches differ? What do you think are the advantages of each approach?
2. As your textbook notes, economists inevitably approach their studies with certain assumptions about, among other things, human nature. What kinds of assumptions about who we (humans) are and what we fundamentally desire have you seen so far in this course? Do you agree with these assumptions or disagree, and why?
