Concept explainers
The complement system is composed of soluble proteins that catalyze bacterial opsonization and cell lysis. Complement is triggered by antibody interactions or by interactions with nonspecific activators, such as mannose-binding lectin. Complement activation may be a product of either innate or adaptive immunity. Complement may enhance phagocytosis, cause target cell lysis, or induce an inflammatory response.
Describe the complement system. Is the order of protein interactions important? Why or why not? Identify the components of the mannose-binding lectin pathway for complement activation. Identify the components of the alternative pathway for complement activation. How do these complement activation pathways differ from the classical pathway?

- Identify the indicated structure (Saprolegnia). a. antheridium O b. oospore c.sperm d. auxospore e. tetraspore Of. zygosporearrow_forwardUsing information from the primary literature (several references have been provided as a starting point below) please answer the following question: Based on your review of the literature on rewilding, what are the major scientific pros and cons for rewilding? Please note that the focus of this assignment are the (biological) scientific issues associated with rewilding. As will be discussed in class, there are a number of non-scientific issues involved or implicated in rewilding, all ultimately affecting the public acceptability of rewilding. Although these issues are important – indeed, critical – in this assignment you should focus on the biological science issues and questions. Details: You must enumerate at least two pros and at least two cons. Your answer should be no more than 500 well-chosen words, excluding references. Think carefully about how best to organize and structure your answer. Aim for high information density: say a lot, but say it succinctly. Recall Nietzche’s…arrow_forwardUsing information from the primary literature (several references have been provided as a starting point below) please answer the following question: Based on your review of the literature on rewilding, what are the major scientific pros and cons for rewilding?

- Now draw a rough sketch of what the control data might look like if in addition to the specific binding, there was also a considerable amount of nonspecific binding (again using a normal dose/response curve) (do % total bound ligand vs concentration)arrow_forwardWhat are functions of cuboidal cells in the kidney? Select all that apply. Concentration of gases Dilution of chemicals Secretion of molecules Nutrition to tissues Support of tissues Absorption of moleculesarrow_forwardquestion1 In plants, epithelial tissue is only found as the outermost cell layer and acts as a barrier. In humans, epithelial tissue is found inside the body as well as on the surface. What function(s) does/do epithelial tissue carry out in humans? Select all that apply.
