A virus such as influenza is only one type of pathogen that can invade the human body and cause disease. Different pathogens interact with different components of the immune system in different ways.

(a) Describe the role of skin and mucosae as surface barriers and the mechanisms that enable these anatomical structures to prevent infections.

(b) Discuss three examples of how the lymphatic and immune systems work together both structurally and functionally to fight infections such as influenza.

One of the many immune system functions is to protect individuals from pathogens such as the influenza virus. Explain how innate immunity (non-specific defense) and adaptive immunity each respond differently to exposure to influenza virus?

1.How did plants contribute to the first mass extinction event? Please answer in detail.

2.Take a look at the Revive and Restore project. What are two animals they are attempting to bring back? How? Will these be identical to the original? Is this project worth doing?

5. Below is a table showing composition data for clove oil, obtained using two different detection methods (with the same sample), FID and mass spectrometry. Explain why the composition (based on relative peak areas of the GC trace) is different for these data sets. Are either of these the “real” composition of the clove oil?

Hint: Response factor

The main topic or concept will be “CELLULAR RESPIRATION and PHOTOSYNTHESIS”. From this main concept, you will branch out and link to the other concepts.

Link the concepts with connectors and labels if there are concepts that are linked between units. Note: the connecting arrows do not have to be linear, they may be curved.

You may choose to use the ILC Mind Mapping Tool to create your concept map.

Tips for constructing a Concept Map:

• Start with a major theme or concept. This is usually at the top of the page or in the middle of the page, but it does not have to be.
• Shift is from more complex to less complex idea or major to minor. These ideas or concepts should be contained in boxes or ovals and should only be one or two words.
• Connecting lines are drawn between concepts to recognize their relationships. Linking words are placed on the lines stating the relationship between concepts. Linking words: Contains, is a part of, involves, uses, etc.
• Cross links can be made between one part of the concept hierarchy or classification and another.
• Optional: Colour can be used to follow relationships or as a visual aid.

Sample Concept Map

Below is an example of a concept map that explores concepts related to the conservation of momentum.

Regulation of Glycogen Metabolism (McKee page 317-323)

1. Compare activities of glycogen phosphorylase and glycogen synthase based on storing glucose energy in a cell
2. Describe the stimulus for the pancreas to release glucagon based on blood glucose concentration
3. Describe the target for the glucagon signal based on the cell type that has receptors for glucagon
4. Describe the activity of glycogen phosphorylase based on glucagon stimulation of the cell
5. Describe the activity of glycogen synthase based on glucagon stimulation of the cell
6. Describe the result of glucagon stimulation based on glucose release to the blood
7. Describe the activity of glycogen synthase based on insulin stimulation of the cell
8. Describe the activity of glycogen phosphorylase based on insulin stimulation of the cell

What are the ways in which electrical and chemical synapses differ? What implications do these differences have on how they are used in the nervous system?

What is an EPP? What is a MEPP? What is a subthreshold EPP? How do they differ?

What does it mean to say that neurotransmitter release is quantal? How do studies of EPPs reveal this fact? What does one quantum of neurotransmitter represent?

What experiments show that calcium influx is the trigger for neurotransmitter release? What criteria define a neurotransmitter? What experiments address each of these criteria?

What determines whether a postsynaptic cell is depolarized or hyperpolarized by a neurotransmitter?

What are the two different categories of neurotransmitter receptors? How do they differ?

What is an EPC? How is it related to an EPP?

What does the reversal potential of an EPC represent? Why is it important to know?

What is the difference between an EPSP and an IPSP? What determines what kind of PSP it is?

According to the World Health Organization (WHO), Infertility is the inability to conceive a child. A couple may be considered infertile if, after two years of regular sexual intercourse, without contraception, the woman has not become pregnant (and there is no other reason, such as breastfeeding or postpartum amenorrhoea). Primary infertility is infertility in a couple who have never had a child. Secondary infertility is failure to conceive following a previous pregnancy. Infertility may be caused by infection in the man or woman, but often there is no obvious underlying cause.

Evolution occurs as a result of natural selection. You have looked into the fossil evidence of the transition as well as the genetic basis of the genes responsible. For this section, theorize and describe how natural selection selected for the adaptation and why it was successful for the organisms in question.
