Type a 500-600 word response to this topic to be submitted for assessment:

While an immune response to a pathogen such as a Covid 19 will involve many features of immunity we have learn about, a critical aspect will be the T cell response. T cells, once activated can differentiate into one of the various effector T cell subsets that are known and in particular to this conversation, the CD4 T subsets, Th1, Th2 and TH17 cells and the CD8 cytotoxic T cell subset.

Now focusing mostly on the adaptive T cell immune response to a viral infection, describe the key immunological events that would occur upon infection with a virus (generic) that would lead to a effective cytotoxic T cell response and how this would assist in clearing the virus.

A binary string is a “word” in which each “letter” can only be 0 or 1

Prove that there are 2^n different binary strings of length n.

Note:

• Your goal is to produce a properly constructed proof by induction, but this does not mean you have to follow
• Mathematical induction, step-by-step..
• Write the statement with n replaced by k
• Write the statement with n replaced by k+1.
• Identify the connection between the kth statement and the (k+1)th statement.
• Complete the induction step by assuming that the n=k version of the statement is true, and using this assumption to prove that the n=k+1 version of the statement is true.
• Complete the induction proof by proving the base case.
• point-by-point.
• ANOTHER IMPORTANT NOTE:
• Make sure you are addressing the given statement: "there are 2ⁿ different binary strings of length n” !!! So your solution should primarily be discussing binary strings. Yes, the fact that 2^k+1 = 2^k∙2 will be useful in your solution, but it should not be the sole content of your solution, as by itself that equality is a fact about exponents, not a fact about binary strings.

Create a Word file containing the following: The full name of the “test subject” The test subject is a person, not yourself, who can say the names of the products. The best test subject is one who is adamant about being an expert who can distinguish brand A from B. You cannot be the test subject because you generate the sequence, and the test subject cannot see it for an unbiased test. Pets and babies are not allowed as they cannot speak the names of the products for recording the responses of the test subject. Names of two similar products Cannot be easily identified by appearance, shape, or color. Examples A description of the process chosen from Randomization Methods to randomize the order the samples will be served. The list of the random order the 20 samples will be served. The test subject cannot be exposed to the order the samples are served.

A. Choose the word that makes this sentence correct: The higher/lower the narrow-sense heritability of a trait, the faster you would expect that trait to respond to selection.

B. Explain your answer from part A. Identify the equation you could use to predict the response of a trait to selection (1 pt.). Describe mathematically how changing the narrow-sense heritability would lead to the outcome you identified in part A
