Document Summary

Geology: science and study of the earth: minerals and rocks around the region, volcanic landforms and processes, hydrologic processes, hillslope and mass wasting processes, fluvial processes and landforms, glacier processes and landforms. Hydrology: study of movement and distribution of water throughout the earth. 3 major components: core: centre of earth (75% = oxygen and silicon, oxygen - 47, silicon 28% Iron 5. 0: aluminum 8. 1, calcium - 3. 6, sodium 2. 8, potassium 2. 6% We know this because of seismographs and earthquakes. Inner core = solid iron and some nickel: mantle: solid shell of ultramafic minerals surrounding the core. Ultramafic: lots of magnesium and iron (mg, fe: crust: thin outer layer composed of mafic and felsic. Felsic = ca, al, si rocks, mostly igneous (made from fire) Continental crust: ~35 km thick (2 layers upper felsic and lower mafic) Oceanic crust: ~7 km thick (composed of mafic rocks dark rocks, black) Mohorovicic discontinuity (the moho ): boundary between crust and mantle = sharp.

Matt and Maria have now received and begun to eat their Chinese takeout. They have accomplished biting off a portion of a piece of their General Tso's chicken and rice and proceeded to chew and swallow. For this report, you will describe the path the chicken and rice follows and the physiological processing that take place to convert the chicken and rice into their nutritional components that can be used by the body for energy and homeostatic processes. Consider the following as you proceed through your research and discussion of this topic.

1.Through which organs, and in what order does the bolus of food travel?

2. How long does the food remain in each segment of the digestive tract and what physiological processing takes place during this time?

3. What role does the autonomic nervous system play in controlling the movement of food through the digestive tract? What other physical or physiological factors can impact the movement of food though the digestive tract?

4. What specific enzyme or other digestive substances are associated with each segment of the digestive tract and which cells produce these substances? What specific components of the chicken and rice (proteins, carbohydrates, etc.) are processed by each of these substances?

5. What role do the accessory digestive organs play in the process? What are the specific cells of each of these accessory organs and what substances do they produce? Where in the digestive tract are the substances introduced into the digestive process?

6.What is the ultimate fate of the digested chicken and rice? What was the initial biological structure of the nutritional components first consumed (example proteins breaking down to their simpler components) and what are the resulting products resulting from digestion that are now ready and available for use by the body for energy and homeostasis?

7. What is the fate of the solid and fluid components that are not absorbed into the body? When and where does control of movement of digestive tract content transition from the autonomic nervous system controlled smooth muscles to peripheral nervous system control of voluntary skeletal muscles?

1. Deep sea thermal vents are characterized by extremepressures, very high water temp (exceeding 100 celsius) and veryhigh concentrations of minerals. What type of prokaryotic organismsare most likely to be found there and why?

Archaea; tetraethers are morethermally stable.

Archaea; the partial membranessurrounding the DNA provide more protection.

Bacteria; the peptidoglycans in thecell walls keep them from overheating.

Bacteria; they use the energy from the minerals to power theirchloroplasts.

2. Farmers often practice crop rotation to help enrichagricultural fields. Why are beans and other legumes often used inthe rotations?

Legumes remove toxins from thesoil.

Less carbon dioxide.

Bacteria in legume root nodules arenitrifiers.

Legumes enrich the soil by formingheterocysts.

Beans fix nitrogen.

3. The fungus Penicillium produces a compound thatblocks peptidoglycan assembly. Why is a fungus trying to killbacteria?

The compound produced by the fungusis used for nitrogen fixation, the antibacterial properties areaccidental.

The fungal compound is produced inresponse to a bacterial invasion of the fungal hyphae.

Fungi and bacteria are bothdecomposers and compete for resources.

Fungi eat bacteria.

4. If Chlamydia is often asymptomatic, why is it necessary totreat it?

Pelvic inflammatory disease is apotential complication and can render women sterile.

Tertiary chlamydia causesneurological problems.

Chlamydia infection is a major riskfactor for cervical cancer.

Vertical transmission of chlamydia causes birth defects.

5. A mutant strain and the wild-type have different growthrequirements, they are given below.

Wild-type growth factors: A,B,C,D
Mutant growth factors: A,B,C,D,E

Select all the true statements concerning this situation.

It is possible to formulate a mediathat will allow the mutant to grow but not the wild-type.

A minimal medium will allow themutant to grow.

The mutant is auxotrophic.

Replica plating would be used toidentify the mutant.

An early stop codon may have occurred in the mutant.

6. Cell X has 45% adenine in it's genome and a thickpeptidoglycan cell wall. It is most likely a(n)

cyanobacteria

fungal endospore

low CG Bacteria

thermophilic archaean

actinobacteria

7. Are transformation and transduction the same process?

No; only transformation passes ongenes for pathogenicity.

Yes; they both involve theacquisition of viral genes.

Yes; both processes transferspecific gene products to a specific bacterium.

No; although both involve gene transfer the sources of thegenetic material differ.

8. In terrestrial environments, nitrogen fixation only occurs insoils. Why is this the case?

	Free oxygen acts and atranscription inhibitor of nif genes.
	The enzymatic activity of thenitrogenase complex is inhibited by oxygen.
	UV-radiation denatures thenitogenase enzyme complex.
	nif genes are sensitive tolight.
