1. What is the importance or advantage of studying "Drug Repurposing" for a better understanding of the human disease drug discovery process?

2. Provide two examples of human diseases where researchers used this concept or research strategy. What is the cellular mechanism of disease, or signaling pathway targeted by these researchers? Please cite two sources using PubMed!

3. What are the potential disadvantages or challenges of drug repurposing?

1. List possible causes of CCD that Mark, Dave, and Tanya were discussing and briefly describe how each can contribute to honeybee health:

a.

b.

c.

d.

e.

f.

2. Do you think genetically modified (GM) crops could contribute to symptoms of CCD? Explain.
3. What changes in agricultural practices could improve the environments of the honeybees?
5. What actions could the general population take to support the health of honeybees and other pollinators?

1)The following are the steps for B-cell activation. The steps are in an incorrect order.

1. B cells display antigens in MHC class II receptors on the cell surface.

2. Antibodies released by plasma cells bind to antigen so they will be destroyed by other cells of the immune system.

3. B cells rearrange their DNA to create a unique B-cell receptor.

4. B cells become activated by interacting with helper T cells.

5. B cells undergo clonal expansion.

6. B cells digest antigens that bind to the antibodies on their surface.

What are the steps in their correct order of occurrence?

2) How are antigens processed before binding to MHC class I molecules?

a-  They are digested in the cytoplasm of the cell by the proteosome.

b-  They are digested by enzymes in the endoplasmic reticulum

c-They are digested by enzymes in the late endosomal compartment

d- They are digested by enzymes in the endocytic vesicle.

3)  Both MHC class I receptors and MHC class II receptors are synthesized on the rough ER. What keeps MHC class II receptors from binding to antigens while in the ER?

a- The MHC class II receptor has its binding site covered by a protein called the invariant chain. Until that is removed, it is unable to bind to any antigens.

b- There are no antigens in the ER compartment for MHC class II to bind.

c- The MHC class II molecules are kept in a separate compartment of the ER so that they cannot mix with antigens yet.

d- Any antigens bound to the MHC class II molecule are removed by enzymes in the Golgi complex.

1. Define the term “population” in ecology:

2. In this assignment we will be discussing the species of honey bees; come up with an example of a honey bee population (Make sure to use the ecological meaning of the term “population:”

3. Do you think honey bees are K-selected or r-selected species? Explain.

4. Honey bees are keystone species. Define the term “keystone species” and explain why it applies to honey bees:

Phenformin is a drug that was once prescribed to treat type-2 diabetes. However, it was banned by the FDA because patients started presenting complications from lactic acidosis. If phenformin increases anaerobic metabolism, provide a rationale for lactic acidosis in phenformin-treated patients. Your answer should include a metabolic pathway diagram in your rationale.

Write the net biochemical equation for the biosynthesis of the non-essential amino acid aspartate from pyruvate, carbon dioxide and ammonia from the necessary elementary reactions or steps. (you must include all necessary elementary steps for full credit)

I have to write an outline for a persausive speech about vaccines. I am for vaccines, My arguments so far include that the autism-vaccine doctor got his license taken away and 2. it is important to get vaccinate because people with auto immune diseases cannot fight off diseases as well as protecting infants and teens from serious diseases like measels Topic: General purpose: Specific purpose: Central idea: Introduction: Body Main point 1 Support Support Main point 2 Support Support Main point 3 Support Support

What is the G-factor in the strain gage, and why do we need to use materials with a high G-factors
in strain gages used for medical purposes.

A mutation that causes cystic fibrosis has quite a high rate of people that are heterozygous and do not show symptoms of the disease. What does this tell you about the function of the cystic fibrosis gene?

The recombination frequency between genes A and B is 4%. The recombination frequency between genes B and C is 17.3%. If in a progeny of 1926, only 6 double crossovers have been observed, what is the coefficient of coincidence?______ And the interference?______
