Imagine that you are walking through the desert and you get scratched by a thorn on a mezquite, unfortunately for you the thorn was previously covered with pathogenic bacteria X by droppings of vultures perched at the top. You developed a nasty skin infection that rapidly turns into a systemic one. You survive, and your doctor says that you have very good quantity of IgG anti-bacteria X that would probably make you immune to another infection.
Using a cartoon describe to chronologically what cells
would first respond to skin infection and explain how and when the adaptive immune system will get involved.

3. In some species, sexual ornaments may evolve to signal to females that the male will providehigh levels of paternal care. However, in other species, such as the red-crested cardinal picturedbelow, there is a negative correlation between the expression of the ornament and paternal care.a) In such species, how might we explain female preference formales with redder heads? b) Imagine that females in the population vary in body condition.How might we expect female mate preferences to vary with femalebody condition? Explain your answer. c) What effect might this have on the strength of sexual selectionfor redder heads?

- 1. Mice and Genetics Research: Imagine you are working in a genetics lab with the house mouse Mus musculus, a model organism for genetics research. You want to determine whether a trait you have discovered in mice is dominant or recessive. Explain how you would design an experiment to answer this question. Predict what types of outcomes are possible. Which would indicate that the trait is dominant? Which would indicate that it is recessive? 2. Model Genetic Organisms: Why are mice considered a model genetic organism? Would humans fit this descriptionarrow_forwardIn certain parts of Africa where malaria is prevalent there is an apparent advantage to being heterozygous for the recessive allele that causes sickle-cell anemia. Suppose a couple, both heterozygous for this allele, plans to have four children. What is the probability that all four will be heterozygous for the sickle-cell allele (assuming that none are from multiple births)? Explain how they can determine this using a Mendelian cross.arrow_forwardDon't give AI generated solution Fill in the blanks to complete the process of cellular respiration ? give typing explanationarrow_forward

I am aware of how they work in isolation e.g response to temperature, light, salinity, drought, nutrients and toxins, but not how the signalling occurs simultanously i.e transcription factors or ezymes present in two systems at once protecting the plant from both things.arrow_forwardtended Response (F24) O 3:58:01 remai Use the table below to construct a phylogenetic tree for a group of alien organisms found on the planet Kepler 22B by the astronomer D. Liscious. Ph.D. The common ancestor of all these organisms was green, silicon-based, with 2 legs, 4 dataports, 1 sex, and did not possess powered flight, x-ray vision, or interdimensional awareness. Assume the hypothesis of parsimony is valid and that all taxa are extant except for Taxon A, which is extinct. (10 pts) You should draw your tree on a piece of paper. Then, take a photo of it, save as a file, and upload it here. Please make sure your tree is neat and easy to read. Table 1. Kepler 22B taxonomic diversity with derived characters.

This might mean that, due to the rain shadow effect, the windward sides of mountains might be wetter, while the leeward sides of mountains might be drier. Using what you know about plant taxonomy and ecological relationships, propose a justified, ecological hypothesis on how plant community composition would change on each side of the mountain. Your answer should contain two parts: The hypothesis and the ecological justification addressing the bold points above.arrow_forward
