Explain how diet plays a role in host susceptibility to infection, focusing on the role of diet in the development of inflammatory bowel disease
What will be an ideal response?
Answer: Diet alters the normal flora, allowing opportunistic pathogens a better chance of multiplying and increasing the overall susceptibility of the host to known pathogens. For example, inflammatory bowel disease (IBD) is strongly correlated with diet and is caused by an imbalance in the normal microbiota. For example, a diet rich in animal protein can contribute to the presence of harmful metabolites in the large intestine that contribute to leaky gut and inflammation.

Answer the following statement true (T) or false (F)
A maternal effect mutation bicoid (bcd) is recessive. The bcd allele makes no Bicoid protein. In the absence of the Bicoid protein, product embryogenesis is not completed and eggs fail to hatch into viable larva
Consider a cross between a female who is heterozygous (bcd+/bcd) and a homozygous mutant male (bcd/bcd). a. How is it possible for a male homozygous for the mutation to exist? b. Predict the outcome (normal and/or failed embryogenesis) in the F1 and F2 generations resulting from this cross.
