QUESTION 7 - Du0chenne muscular dystrophy (DMD) is recessive sex-linked disorder, which causes muscle degeneration and premature death. A couple is pregnant with a boy and neither have DMD. The father's family has no history of DMD, but the mother is unsure of her genetic family history as she was adopted. The mother decides to take advantage of some of the new genomic screening tests and learns information about a large number of her genes. She finds that she is a carrier of the DMD affected allele.

A. What is the mother's genotype? Explain your reasoning.

B. What is the father's genotype?  Explain your reasoning.

C. What is the likelihood of the male foetus having DMD? Use a punnet square to explain your answer.

QUESTION 8 - A 79-year old woman, who was visiting her 82-year old husband at the hospital where you work, cuts herself on the sharp edge of a rubbish bin. In a few days, she developed a wound infection. Lab cultures were completed and methicillin-resistant Staphylococcus aureus were shown to be present. Consider this story in relation to microbiology principles, and complete the circle of infection by identifying the infectious agent, the reservoir, the mode of transmission and the portal of entry.

QUESTION 9 -

1. Write the name of each vessel type pictured in the table below in the corresponding box.

2. For TWO of the vessels, complete the row to include (a) the key identifying feature of that vessel type, (b) the layer in which this key identifying feature is found, (c) indicate whether the key identifying feature is notable because it is present in large amounts OR present in small amounts OR absent and (d) how this key identifying feature relates to the function of that vessel.

QUESTION 10 -

A. Indicate which phase of haemostasis is depicted in each of the pictures below.

B. Provide a brief description of each phase, using the diagrams to help explain your answer. Note: it is not necessary to label parts of the diagrams, but you may do so if it will help you explain the phases. 

QUESTION 11 - The action of the enzyme lactase is depicted in this diagram. For each location (a-d), choose the MOST appropriate term from the table below and write the corresponding number on the diagram.

QUESTION 12 - Complete the paragraph below using terms from the list provided. For each blank, choose the term that BEST fits. More words than necessary are provided, and terms may be used more than once.

Digestion of carbohydrates begins in the _________ via the action of the enzyme _________. Enzymatic action is a form of _________ digestion. Carbohydrates must be broken down into _________  before they can be absorbed into the bloodstream.  Lactase is an example of a _________ that is produced by the brush border of the            _________.

QUESTION 13 - Complete the table below to outline TWO feedback mechanisms (blood pressure and another of your choice). Your second mechanism must be one that is mediated by a hormone of the hypothalamus- pituitary axis; record both the mechanism and the hormone in the table below.

For both blood pressure and your chosen mechanism, you will need to (a) describe the main role of each feedback mechanism, (b) identify the receptor, control centre and effect or and (c) specify whether this is a positive or negative feedback mechanism. Body temperature is provided as an example of the level of detail required.

QUESTION 14 - The paragraph below relates to this graph, which describes changes in membrane potential over time.

A. Fill in each of the blanks to complete the paragraph using terms from the list provided. More words than necessary are provided, and terms may be used more than once.

B. Circle and label the appropriate parts of the graph as directed below.

At the start of an Action Potential, an ion channel opens in the membrane. Overall movement of _________  ions is into the cell.  The reason for this is that their concentration is higher_________ the cell; and the inside of the cell is more _________ charged.  Circle and label the point where the voltage-gated ion channel opens on the graph with a 1.

The Action Potential has progressed. Now those channels close, and another group of ion channels open.  Overall movement of the second ion, _________, is out of the cell.  The cell membrane is now undergoing _________.  Circle and label this process on the graph with a 2.

The _________ period is the period of time in which the nerve membrane cannot respond to a stimulus (start another action potential) no matter how strong the stimulus is.

QUESTION 15 - The results of dipstick urinalysis of two urine samples are listed below. Sample 1 belongs to a 25 year old male computer programmer. Sample 2 belongs to a 22 year old female triathlete.

A. For each parameter, fill in the normal values. (Hint: Refer to the Week 10 laboratory activity to get you started).

A. What personal protective equipment should be worn when handling someone else's urine? Why?

Choose ONE of the samples above and use the free response section below to answer the following questions.

B. Compare the normal and sample values. List any abnormalities you observe in the section below.  Are they higher or lower than normal?

C. Give a situation in which you might expect to see these changes in an otherwise healthy individual.

D. What might have been happening in the nephron to cause these abnormal results? Explain your observed abnormalities by linking them with the part of the nephron involved and the process involved (ie filtration, secretion or reabsorption). Ensure that any relationships between the abnormal readings are made clear in your response.

QUESTION 16 - Regarding ventilation, which process is active - inhalation or exhalation? Explain your answer.

Contraction of which muscle/s produces the movement labelled "2"?

At label "3", is pressure outside greater than or less than pressure inside the lungs?

Is the pressure in the space labelled "4", higher or lower compared to the atmospheric pressure?

At label "8", is pressure outside greater than or less than pressure inside the lungs?

Name any ONE muscle that contracts to cause the extra movement required when you need to expire forcefully (indicated by the arrows labelled "6" and "7").

QUESTION 18 - Describe the changes in volume and pressure inside the chest cavity during a normal exhalation. Explain why these changes are occurring, and the effect upon airflow.
