Why are water tables dropping around the world? What are some negative impacts of falling water tables?

Three classes of proteins are responsible for tagging proteins destined for degradation by the proteasome complex. Name the enzymes and briefly describe the function of each enzyme involved.

1. Patients with inflammatory bowel disease (IBD) have been shown to have gastrointestinal (GI) microbes distinct from healthy patients that are matched for age/weight/diet and other variables. One hallmark of IBD is the leakage of IgA from the GI tract into the bloodstream. How would you determine if the GI microbiota of IBD patients can cause IgA leakage (in detail)? Assume that you have access to GI microbiota samples from IBD patients and matched healthy controls, a colony of germ-free mice, and a blood test for IgA. (3 pts)

THIS IS ALL THE INFORMATION PROVIDED

• How to manage soil resources?
• How to manage genetic resources?
• How to manage pests sustainably?

These Questions are from the Textbook "The Environment and You"

You will investigate how unnatural amino acid mutagenesis works. Take time to examine what changes needed to be made to the tRNA to allow for an unnatural amino acid to be used instead of the native substrate. Also focus on what codons are used to recognize the modified tRNA. How many different codons are there that can be used? What are they called?

What would be areason why a cell does not have death phase in a bacterial growth curve?

3. Air Quality                                                                              Chapter 10

• Which are the sources of air pollution in the stratosphere?
• Which are the sources of air pollution in the troposphere?
• What is the cause for acid rain?

Questions are from the Textbook "The Environment and You"

ESSAY QUESTION

The Central Nervous System is considered “immunologically privileged.” What does this mean?What are the features of the anatomical structures that that enable this status. What are the factors that can cause a breech into the status of this system?

How do these characteristics play a role in the efficacy of treating infections in the Nervous System,and can they contribute to the occurrence of latent infections within this system?

2. Climate Change and Global Warming                                   Chapter 9

• What are the causes of global warming?
• What are the consequences of global warming?
• What are the mitigation and adaptation policies?

Questions are from the Textbook "The Environment and You"

During mismatch repair, how does the cell “know” which strand to degrade and repair? Why will it lose this ability after a certain amount of time? Provide a reason that might explain why it is safer to degrade the new strand of DNA rather than the parental strand.

Why do you think that phosphorylation and dephosphorylation has evolved to the point that it has such a prominent role switching proteins on and off in signaling pathways? (as opposed to, for example, using the allosteric binding of small molecules)

One species of plant produces blue, light blue, and white flowers. To determine the inheritance pattern, the following matings were performed:

blue x blue to blue

white x white to white

blue x white to light blue

This example represents a pattern: (choose the best option)

a. Associated with the X chromosome

b.Incomplete Dominance

c. Codominance

d.Mendelian

Describe (in detail) similarities and differences in pond structure between Green Library and OE Ponds. Choose one abiotic and one biotic factor that affects primary productivity. In the context of your results, explain how these factors affect photosynthesis and respiration as well as Net Primary Productivity (NPP) and Gross Primary Productivity (GPP).

Green library pond: Is bigger, more space for species, minimum shade, recives a lot of light, water is more clear (assuming less disposal of nutirents.

OE pond: Is smaller, less space for species, a lot of shade/ almost no sun exposure, water is dark (assuming more nutrient disposal.
