Histamine is involved in which immune response?

Give the poles and zeros of the causal filter represented by the impulse response: h(n) = 4 * (δ(n) + δ(n-1) + δ(n-2))   

The Pfizer-BioNTech and Moderna vaccines are mRNA vaccines. The mRNA in the vaccines contains the genetic information for the viral spike protein. A student is talking with some family members who are concerned about getting the vaccine, and one of them says the following: “It’s just a myth that the vaccines actually protect against COVID-19. The only way to get your immune system to recognize and respond to a viral infection is to get the actual virus. The immune system can’t learn to recognize the piece of RNA or a single viral protein, which is what the vaccine manufacturers claim.” Identify the misunderstandings these family members have about the way the vaccinations work and explain how they can cause a protective immune response.

We shall consider the general method, employed by an adversary,  to prove that no algorithm can always decide a given problem X using less than M questions. For that purpose, the adversary maintains Q, and R_1 … R_M, such that : 1. X(Q) is false2. X(R_i) is true for all i \in 1 … M and such that after k questions from the algorithm:3. Q is consistent with all k answers from the adversary 4. for all i in 1 … M, except for at most k such, it holds that R_i is consistent with all k answers from the adversary.For each declaration from the algorithm, how should the adversary respond?

The _________is a test in which a needle is used to withdraw a small amount of amniotic fluid and cells from the sac surrounding the fetus and later tested.

[Trader Joe’s] a) What specific challenges or concerns should the CEO be aware of as she charts a path to get alignment with her senior team over the next year, and beyond?  Which article(s) from our course might you recommend for her to read?  Explain why you selected your recommendation (any article in our course, whether required or reference) and why it is applicable to this situation. b) How can the new CEO mitigate the risks of these challenges and maximize the chances of successful implementation of the new digital strategy?

Which identity status, common among young adolescents, is determined by adults rather than by personal exploration? For example, a high school graduate’s parents decide she is going to become a doctor and she attends medical school despite not wanting to become a doctor.

Consider the 4 numbers 31, 33, 35, 37.  Assume I think of a particular permutation  (say 37, 33, 31, 35), and that you must find that permutation by asking questions that are answered by “yes” or “no”. To solve that task, what is the smallest number of questions that will always suffice?
