5. Prove the Following: a. Let {v1, . . . , vn} be a finite collection of vectors in a vector space V and suppose that it is not a linearly independent set. i. Show that one can find a vector w ∈ {v1, . . . , vn} such that w ∈ Span(S) for S := {v1, . . . , vn} \ {w}. Conclude that Span(S) = Span(v1, . . . , vn). ii. Suppose T ⊂ {v1,...

(8 pts) Endotoxin is a major cause of septic shock. Describe (2 pts) where endotoxin comes from, (4 pts) the specific steps the innate and acquired immune system takes to respond to endotoxin in the blood stream. Explain the steps from the recognition of endotoxin by the innate immune system to the response by the acquired immune system. (2 pts) how the immune system response leads to septic shock.
