Chemical secretions are one of the main defensive mechanisms in insects. The osmeterium is a unique organ in larvae of Papilionidae (Lepidoptera), which is everted upon disturbance, secreting odoriferous volatiles. Here, using larvae of the specialized butterfly Battus polydamas archidamas (Papilionidae: Troidini), we aimed to understand the mode of action of the osmeterium, the chemical composition and origin of the secretion, as well as its defensive efficiency against a natural predator. We described osmeterium’s morphology, ultramorphology, structure, ultrastructure, and chemistry.

Find all elements of our ring R that have norm 1. Show that no element has norm 2 or 3. Solution a) This element is clearly non-zero, and not a unit. If it is a product of two non-units, then its norm is a product of two integers of absolute value greater than 1, a contradiction b) for this we will assume that P is the principal We need to show that P s not principal, since P^2= (2) (easy to check by direct computation) its order in the class group divides 2, Now P has one generator , then the norm of this generator is 2 so we can say in the equation it has no principal it means if it has no principal with elements it has no norm so we orove for 3 similarly.

At a sudden contraction in a pipe the diameter changes from D_1 to D_2. The pressure drop. Delta p, which develops across the contraction is a function of D_1 and D_2. as well as the velocity, V, in the larger pipe, and the fluid density, and viscosity, mu. Use Du K and n as repeating variables to determine a suitable set of dimensionless parameters. Why would it be incorrect to include the velocity in the smaller pipe as an additional variable? Solution Let DP= F(D1,d2,v,RHO,MU) units dims pressure F/L^2 L V =L/t D = L rho = FL^-4T^2 Mu= F L^-2T First dimensionless group using D1 V mu are recurring variables Pi1 = DelP * D1^a V^b MU^c since this is non dim, obtains Pi1 = DELP *D1/(V*MU) Similarly for P2: new entering variable D2, obtain D2/D1 Similarly Pi3, using rho as entering variable, Pi3 = Rho*D1*V/Mu.

Write short descriptive answer to the following questions Discuss whether the Internet (Web) enjoys freedom of speech similar to the Print media or, Broadcast or, both or, none. Discuss three reasons why the Internet could be considered a relatively easier medium to protect freedom of speech. Describe two examples of contents on the Web (other than that are already censored by laws) that should be considered for censorship. Provide reasoning for your answer. Various organizations and members of Congress suggest requiring Web sites that contain material \"harmful to minors\" to move to a new domain \" xxx\". Give (with justification) two reasons in favor and two reasons against such a requirement. Solution 1.Now a days Internet offers extraordinary opportunities for \"speakers,\" broadly defined. Political candidates, cultural critics, corporate gadflies -- anyone who wants to express an opinion about anything -- can make their thoughts available to a world-wide audience far more easily than has ever been possible before. Mass Media (one to many): Similar to mass media (radio, television, print media), Internet allows the broadcaster to reach a large audience. But, unlike mass media, Internet enables any user to be a publisher or broadcaster since editorial control is shifted from a small elite; editors and producers, to every user. Where mass media represent a closed, edited, communication system, Internet holds an open, interactive communication sphere where everyone can be both speaker and listener. 2..

Why should anyone else care about what I do with my sewage on my own property? Integrate specific examples from course material in your response. Solution Anyone is going to care what you are going to do with house hold sewage generation and disposal of sewage into the environment because sewage may causes high environmental problem - climate change due to presence more non-degradable phosphorous & organic compounds. Human impacts on environmental change via sewage are leading to the following imbalance in the ecosystem at trophic levels. Household-sewage and toxic lead pollutants are other factors responsible for death of the photosynthetic microalgae & macroalgae result in dead zone with photosynthetic biomass. This dead zone formation is mainly have higher impact on nitrogen cycle level of water and nitrogen cycle is going to increase due to higher farm fertilizers mixing into the aquatic zone via storm water finally bacterial activity is going to reduce “dissolved oxygen level” available to the other aquatic species dramatically via aerobic respiration.

Why do viral particles, zymosan on fungi, endotoxin (LPS) from gram negative bacteria, bacterial DNA, and bacterial flagellin each induce the same proinflammatory response, and especially the production of IL-8, IL-12, IL-1, IL-6, and TNF-alpha? What is the link between this and c-reactive protein levels in the blood stream? Solution The immune system is comprised of two branches: innate and acquired immunity. The innate immune system is the first line of host defense against pathogens and is mediated by phagocytes including macrophages and dendritic cells (DCs). The innate immune response relies on recognition of evolutionarily conserved structures on pathogens, termed pathogen-associated molecular patterns (PAMPs), through a limited number of germ line-encoded pattern recognition receptors (PRRs), Upon PAMP recognition, PRRs present at the cell surface or intracellularly signal to the host the presence of infection and trigger proinflammatory and antimicrobial responses by activating a multitude of intracellular signaling pathways, including adaptor molecules, kinases, and transcription factors. Several classes of PRRs, including Toll-like receptors triggers functional maturation of dendritic cells and leads to initiation of antigen-specific adaptive immune responses. Macrophages activated at sites of tissue injury produce a number of cytokines into the bloodstream, most notable of which are the interleukins IL-1, IL-6 and IL-8, and TNF-, which induces hepatocytes to synthesize acute phase proteins (APP) including C- reactive protein. The level of CRP in blood plasma can rise as high as 1000-fold with inflammation. Thus the greatly raised level of c- reactive protein in the blood stream can be viewed as a strategy to overcome the poplulation of pathogens..

Which of following is not a class of the phylum platyhelminthes? Trematoda Turbellaria Nemertea Monogenea. Cestoda Which one of the following statements regarding the origin of metazoans has the most support? Ancient metazoans, similar to members of the phylum Placozoa, have been ruled out as ancestral metazoans. The choanoflagellates share features with the sponges, like having collars of surrounding a flagellum and being colonial. These shared features suggest a link to at least metazoan lineage. Metazoans are derived from many separate of unicellular organisms. Modern sponges have a genetic makeup that reflects their ancestral status. The traditional view of cnidarians relative to germ layers is that cnidaria possess two germ layers, ectoderm and endoderm. only one germ layer, the ectoderm, that differentiates into the two tissue layers. two germ layers, ectoderm and mesoderm. definitely all three germ layers including the mesoglea as it is derived from ectoderm. two germ layers, endoderm and mesoderm. Throughout most cnidarian groups, the basal or pedal disc serves to be the base of the tentacles. harbor sensory cells. generate buds. perform extracellular digestion. attach the cnidarian to the substrate.

What are two ways that meiosis could produce gametes that contain genetic material that is different from the parent cell? What are two ways that meiosis could produce gametes that contain genetic material that is different from the parent cell? What are two ways that meiosis could produce gametes that contain genetic material that is different from the parent cell? Solution Answer: The two ways that meiosis could produce gametes which differ genetically from its parent cells are as under: (1) During meiosis, homologous chromosomes undergo independent assortment. This means that the chromosomes associate in no way with one another. Thus, the gametes so formed may have any combination of paternal and maternal chromosomes. (2) Crossing over results in the exchange of genetic material between homologous chromosomes, resulting in recombinant chromosomes. It occurs during the pachytene stage of meiosis I. This process gives rise to new recombinant varieties and thus the gamete so produced differ genetically from the parentals..

what is the process in society that made this change to advertising objective throughout history? what objective in the list of advertising objectives bears a qualitative change in it or represents a new level of diff Solution Over the years, the advertising objectives has changed with change in societal structure and its morality. Advertising is a process to attract customer towards a product or service and it takes the route to arouse various emotion of the target audience. As the societal value has changed over the years, so has changed the pattern of advertisement to lure the consumer. In earlier days, when advertisindg came into picture, the society used to be closely knitted and had joint families. Hence, it was possible to capture a large audience at a go and that too with a well directed common messaage that includes the societal value of being together. As time progressed, families broken apart and nuclear families arose in the scene-so advertisers started targeting individual people\'s choices and came up with 2-3 versions of a single advertisement that can attract different customers having a same choice but with different mentality. Moreover, the division of society into high income group, middle income group and lower income group made the advertiser think in different ways.The concept of niche-advertising crept in- advertisers started targeting people based on their income. Then came the era of internet that changed the advertising objective all together. Initially the case was to attract the customer towards a product now marketers try to present their product at a place and time when customers need it, Today consumer is busy, having various options to compare - so reaching to the customer at a right time and at a right place is very necessary-so came the practice of using direct mail communication, tracking customer search history to know his/her preferences and present him/her with the exact product they want, came the concept of testimony from satisfied customer to gain confidence of other customers. Qualitative changes over the years that represents a new level of difference: - Niche advertising- Targeting preferences of individual class - Personal Targeting through internet- helped to save conumer efforts and made the experience rich..
