Describe how/where protein digestion occurs in the body and how zymogenic serine proteases contribute to the process.

After researching neurotensin , decide which part of that peptide pathway to target so a  drug will enhance learning and memory.

a) Which part of the peptide pathway will you target?

b) How will your drug affect that target? Remember to use your core pharmacology concepts to help you decide this.

4) Prepare a 1 page poster (A3 size) advertising your new drug. Your poster must include the following required elements:

a) The name of your new drug (be creative!).

b) A brief description of the peptide pathway your drug acts on, and how this peptide affects learning and memory.

c) An explanation of the mechanism of action for your drug. Use a flow diagram to help explain this.

d) A catchy marketing slogan to advertise your drug. (For the purposes of this exercise, we will disregard the normal regulations that govern the marketing of pharmaceuticals in Australia!).

e) Reference information. You can choose your preferred referencing style, and where you place this information on your poster (although it must be on the same page as the poster, not on the back). There is no minimum number of references.

Explain how smoking alters the anatomy and physiology of the respiratory tract and leads to emphysema.

Given: bicoid genes are maternal genes; kruppel genes are gap genes, even-skipped genes are pair rule genes, gooseberry genes are gooseberry. Predict the effect of scenarios below on expression levels of each of these gene classes in the embryo described (will expression increase, decrease, or be unaffected?) and explain the reason for your prediction.
a. a fly embryo has a mutation that blocks expression of the kruppel gene

b. a fly embryo has a mutation that blocks expression of the bicoid gene.

c. a fly embryo has a mutation that increases expression of the even skipped gene.

For this week's discussion, choose an animal that you find interesting, and report one adaptation that it possesses. Be sure to report the environmental condition that the adaptation helps the animal to overcome and the references you used to locate the information.

Post-Lab Questions

State your hypothesis (developed in Step 8) here. Be sure to include what you think the pH will be, and why.

What is a neutralization reaction?

When might neutralization reactions be used in a laboratory setting?

At what point was the solution in beaker “B” neutralized?

What do you think would have been the results if a stronger solution of sodium bicarbonate was used? Would it take more or less to neutralize? What about a weaker concentration of sodium bicarbonate?   

Which of the following is arguably the world's first true microbiologist?

Determine which of the following observations are testable. For those that are testable: Determine if the observation is qualitative or quantitative Write a hypothesis and null hypothesis What would be your experimental approach? What are the dependent and independent variables? What are your controls - both positive and negative? How will you collect your data? How will you present your data (charts, graphs, types)? How will you analyze your data? Observations 1. A plant grows three inches faster per day when placed on a window sill than it does when placed on a on a coffee table in the middle of the living room. 2. The teller at the bank with brown hair and brown eyes is taller than the other tellers. 3. When Sally eats healthy foods and exercises regularly, her blood pressure is 10 points lower than when she does not exercise and eats fatty foods. 4. The Italian restaurant across the street closes at 9 pm but the one two blocks away closes at 10 pm. 5. For the past two days, the clouds have come out at 3 pm and it has started raining at 3:15 pm. 6. George did not sleep at all the night following the start of daylight savings.

Biology Ecology Unit

1.

A.) Describe how the phenomenon of bioaccumulation occurs in an ecosystem. What chemical/physical properties make a compound bioaccumulate? Which organisms are affected the most and why?

B.) Which scientist is first credited for bringing this phenomenon to light, what book did she write? Briefly explain the reaction and ultimate outcomes that resulted.

2. Explain how the wildlife values of different seral (successional) stages change during the process of succession in the lowland forests of Western Washington in terms of forage, browse and cover.   Be sure to describe how this relates to the diversity and structural complexity of these stages.

Exercise 7: Experimental Variables Determine the variables tested in the each of the following experiments. If applicable, determine and identify any positive or negative controls. Observations 1. A study is being done to test the effects of habitat space on the size of fish populations. Different sized aquariums are set up with six goldfish in each one. Over a period of six months, the fish are fed the same type and amount of food. The aquariums are equally maintained and cleaned throughout the experiment. The temperature of the water is kept constant. At the end of the experiment the number of surviving fish is surveyed. A. Independent Variable: B. Dependent Variable: C. Controlled Variables/Constants: D. Experimental Controls/Control Groups: 2. To determine if the type of agar affects bacterial growth, a scientist cultures E. coli on four different types of agar. Five petri dishes are set up to collect results: ? One with nutrient agar and E. coli ? One with mannitol-salt agar and E. coli ? One with MacConkey agar and E. coli ? One with LB agar and E. coli ? One with nutrient agar but NO E. coli All of the petri dishes received the same volume of agar, and were the same shape and size. During the experiment, the temperature at which the petri dishes were stored, and at the air quality remained the same. After one week the amount of bacterial growth was measured. A. Independent Variable: B. Dependent Variable: C. Controlled Variables/Constants: D. Experimental Controls/Control Groups:
