A. What happens when self-determination mechanisms break down? This would be when your body mistakes your self-tissues for foreign agents. Can you give specific examples of when this occurs and what the end result is?b. Find a primary literature article that discusses in more detail one of the autoimmune responses you have identified in Question 3. This can be an article that describes a new finding in the disease, something to do with treatment of the disease or anything you might find intriguing to read about in more depth. Briefly describe the contents of the paper in a paragraph summary including what results the authors found and what impact it has on the field of immunology. c. Cytokines are of critical importance for communication. Indicate a role for the following cytokines during an infection and which cells can produce that cytokine: IFN a/b, IFN-g, TNF-a, IL-12, IL-6 and IL-10. Based on what you find, can you briefly comment on how cells interact together to produce this cytokine network?

Considering the yellow and green pea color phenotypes studied by gregor mendel: a. what is the biochemical function of the protein that is specified by the gene responsible for the pea color phenotype? (1 point) b. a null allele of a gene is an allele that does not specify (or encode) any of the biochemical function that the gene normally provides (in other words, either no protein at all or only non-functional protein is produced from it). of the two alleles, y and y, which is more likely to be a null allele? (1 point) c. in terms of the underlying biochemistry, why is the y allele dominant to the y allele? (2 points) d. why are peas that are yy homozygotes green? (1 point) e. the amount of protein produced from a gene is roughly proportional to the number of functional copies of the gene carried by a cell or individual. what do the phenotypes of yy homozygotes, yy heterozygotes, and yy homozygotes tell us about the amount of sgr enzyme needed to produce a yellow color? explain your reasoning.

Of seawater increases with decrease in the temperature. therefore, the cold water sinks to the deeper layers at the bottom
