DNA : DNA is the genetic material of organisms. It contains the genetic information coded within itself . And genetic information is passed onto over generations. Also DNA provides template for formation of RNA and also replicates itself when cell gets divided. DNA is composed of purines and pyrimidines connected through hydrogen bonds on a sugar phosphate backbone. These bases form codon for protein synthesis. RNA : RNA is ribonucleic acid which differs from DNA in sugar composition and in RNA thymine is replaced by uracil in RNA. RNA is of three types . mRNA which js useful for formation of Protein . rRNA OR RIBOSOMAL RNA is useful for ribosomes. and tRNA or Transfer RNA is important component of protein synthesis. So RNA is the key component of proteins in the cell. PROTEINS: Proteins we can say is one of the building blocks of cells in an organism. All enzymes required for physiological processes are proteinaceous in nature. So they are required for every minor processes of an organisms. CARBOHYDRATES : Carbohydrates are also one of the most important biological macro molecule. Several sugars are involved in energy generation in the cell. So carbohydrates basically are involved in generation of energy in the cell. ATP is produce by sugar metabolism only. LIPIDS : Lipids are also source of energy in cell and equally important biological macromolecule for teh cell. Stored lipids in the cell provides energy and from from lipids various metabolic pathways are important.

1.Chemical composition of DNA is -It is long chain polymer composed of monomers called nucleotides.Each nucleotide is composed of three subunits.These are a)Nitrogen base,b)Sugar,c)Phosphate. a)Nitrogen bases:Pyrimidines and Purines b)Sugar:Ribose sugar c)Phosphate:one central phoshporous with 4 oxygen atoms 2.Replication and its importance: DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule. The importance of this process is that it occurs in all living organisms and it is the basis for biological inheritance.If DNA never replicated,meiosis and mitosis would slowly halves the size of the genome until each cell would die,which probably would not take long. 3.Function of Protein synthesis: Protein synthesis is important because proteins control the activities of cells.Without these many of the processes in the body would fail or not work properly. 4.Comparison of Transcription and Translation: Transcription is the synthesis of RNA from a DNA template where the code is converted into a complementry RNA code whereas Translation is the synthesis of a protein from an mRNA template where the code in the mRNA is converted into an aminoacid sequence in a protein. 5.List and functions of three types of RNA: a)mRNA or Messanger RNA --Its function is that it transcribes the genetic code from DNA into a form that can be read and used to make proteins.mRNA carries genetic information from the nucleus to the cytoplasm of a cell. b)rRNA or Ribosomal RNA --Its function is that it directs the translation of mRNA into Proteins. c)tRNA or Transfer RNA--It brings or transfers aminoacids to the ribosomethat corrosponds to each three nucleotidecondon of rRNA.The aminoacids then can be joined together and processed to make polypeptides and proteins. 6)Compare and contrast DNA and RNA: DNA is a long polymer with deoxyriboses and phosphate backbone,having four different nitrogeneous bases:adenine,guanine,cytosine and thymine.Whereas RNA is a polymer with a ribose and phosphate backbone,having foue nitrogeneous bases:adenine,guanine,cytosine and uracil. 7)Semiconservative nature of DNA:In this replication would produce two copies that contained one of the original strands and one new strand.

Food and jobs comes hard in hand. To which a labor is convict to do under skill jobs as well for survival. At the time of the great depression Americans had to fight for what little they had, and as the movie showed many people went hungry. Modern Times looks toward the future, but not with enthusiasm. Often described as a satire of the machine age, It has in fact a broader theme: the dehumanizing effects of many aspects of modernity, including industrialization, bureaucracy, urbanization, and law enforcement. 3) From the movie a prospect employee should not forget about the social ills and failings of own day even if present age is seems far better than that was shown in the film. A dilbert-like early scene shows the Tramp trying to take a break during work hours in the washroom — only to have a big-screen image of the boss’s head suddenly appear on the washroom wall and order him to quit stalling and get back to work. Modern audiences watching this scene may reflect ruefully on the everyday reality of electronic surveillance in the workplace. Now, obviously there’s nothing new about widespread poverty and want, but unemployment as we know it today is a comparatively recent development — a byproduct of the modern workforce economy that requires everyone to \"get a job.\" 4) The major ethical dilemma consists whether out of povertty stealing is right or wrong. However this movie glorifies the struggle of the poor rather than vilifying them for stealing food to survive. By glorifying the struggle the movie takes on yet another social issue: when the poor steal to eat it is not criminal, just survival.

Web sever environment: A Web server is a program that uses HTTP (Hypertext Transfer Protocol) to serve the files that form Web pages to users, in response to their requests, which are forwarded by their computers\' HTTP clients. Dedicated computers and appliances may be referred to as Web servers as well.The process is an example of the client/server model. All computers that host Web sites must have Web server programs. Leading Web servers include Apache (the most widely- installed Web server), Microsoft\'s Internet Information Server (IIS) and nginx (pronouncedengine X) from NGNIX. Other Web servers include Novell\'s NetWare server, Google Web Server (GWS) and IBM\'s family of Domino servers. Web servers often come as part of a larger package of Internet- and intranet-related programs for serving email, downloading requests for File Transfer Protocol (FTP) files, and building and publishing Web pages. Considerations in choosing a Web server include how well it works with the operating system and other servers, its ability to handle server-side programming, security characteristics, and the particular publishing, search engine and site building tools that come with it. Advantages of using a web server within your development environment: Problems posed by web server environment and methods to solve: Various high-profile hacking attacks have proven that web security remains the most critical issue to any business that conducts its operations online. Web servers are one of the most targeted public faces of an organization, because of the sensitive data they usually host. Securing a web server is as important as securing the website or web application itself and the network around it. If you have a secure web application and an insecure web server, or vice versa, it still puts your business at a huge risk. Your company’s security is as strong as its weakest point. Although securing a web server can be a daunting operation and requires specialist expertise, it is not an impossible task. Long hours of research and an overdose of coffee and take away food, can save you from long nights at the office, headaches and data breaches in the future. Irrelevant of what web server software and operating system you are running, an out of the box configuration is usually insecure. Therefore one must take some necessary steps in order to increase web server security. Below is a list of tasks one should follow when securing a web server. 1. Remove Unnecessary Services Default operating system installations and configurations, are not secure. In a typical default installation, many network services which won’t be used in a web server configuration are installed, such as remote registry services, print server service, RAS etc. The more services running on an operating system, the more ports will be left open, thus leaving more open doors for malicious users to abuse. Switch off all unnecessary services and disable them, so next time the server is rebooted, they .

The middle ear bones in mammals are derived from bones in the dentary bone (mandible) of Therapsids. In the Therapsid dentary, there were three bones used in the jaw hinge: the angular, articular and quadrate. The tympanic, malleus, and incus are homologous to the angular, articular, and quadrate Tympanic = Angular Malleus = Articular Incus = Quadrate In early Therapsids, the quadrate, angular and articular were directly connected to the dentary bone in the jaw hinge. These bones were essential for jaw movement. These bones were also utilized for crude hearing capabilities. The next stage of evolution came with the separation of these bones and the dentary. After the bones separated from the jaw, they formed the postdentary rod. It is believed that these the mammalian middle ear bones evolved at least twice. It is believed that monotreme and therian ancestors evolved very similar middle ear bones, but in two separate paths. In monotreme ancestors, there is a mandibular trough, that is believed to have accommodated the postdentary rod. This rod is believed to have been connected to the trough by ligaments. This rod was used for hearing and the quadrate, angular, and articular were no longer needed in the jaw hinge. In therians, the mandibular trough no longer held the quadrate, angular, and articular. These bones were held to the jaw by ossified Meckel’s cartilage. This bridge of cartilage and bone extended away from the dentary and approached the area that would make up the modern ear cavity. The evolution of the mammalian middle ear and jaw joint were pivotal steps in the evolution of mammals. It is also a great example of how classical comparative anatomy, paleontology and developmental biology have come together to piece together how this remarkable transformation of jaw joint to ear ossicles was able to come about. The homologies of the malleus, incus and stapes to the articular, quadrate and columella, and tympanic ring and gonial to the angular and prearticular suggested by comparative anatomy 175 years ago have been recently confirmed by molecular and developmental biology. The recent discovery of new mammali form fossils has allowed careful documentation of the shift from primary to secondary jaw articulation, creating an opportunity to follow the transformation of the post-dentary skeletal elements. This fossil data has been complemented by the study of marsupial development, providing insight into the changing role of the malleus and incus, and the relationship of the primary and secondary jaw joints. We now have a number of unanswered questions. What are the signalling molecules involved in the interactions between the condylar process and the glenoid fossa that create the novel mammalian jaw joint? What are the mechanisms that lead to transformation of Meckel’s cartilage into a ligament allowing isolation of the ear from the jaw? What controls the distribution of secondary cartilages? What controls the timing of differentiation an.

There is an old saying “Do not put all eggs in one basket” Why? Because risk is high.By keeping eggs in different baskets, we reduce risk We try to do same thing through diversification. By investing our capital in different assets , we try to reduce risk. Diversified folios reduce the risk and also the ratio of Risk to reward. If w1, w2 , w3 …wn are weight in the portfolio for assets 1, 2,3 ….n Then,w1+w2+w3+……………………+wn=1 R1, R2,R3,…….Rn are the return of the assets 1, 2 , 3 ….n S1, S2, S3……Sn are the standard deviation of the assets 1, 2, 3 …n Portfolio Return=w1R1+w2R2+w3R3+…….+wnRn Portfolio Variance=(w1^2)*(S1^2)+(w2^2)(S2^2)+………….(wn^2)*(Sn^2)+2w1w2*Cov(1,2)+2w1w3* Cov(1,3)+………+w(n-1)wn*Cov(n,(n-1) Cov(1,2)=Covariance of returns of asset1 and asset2 Portfolio Standard Deviation =Square root of Portfolio variance Risk of a stock is measured by standard deviation. Hence reduction of standard deviation through diversification means reduction of risk. We can take a simple example of two assets 1 and 2 Return of asset1=R1=15% Return of asset2=R2=12% Standard deviation of asset 1=S1=10% Standard deviation of asset 2=S2=8% Correlation of asset 1 and 2=Corr(1,2)=0.1 Covariance(1,2)=Corr(1,2)*S1*S2=0.1*10*8=8 Assume for simplicity, equal amount is invested in asset 1 and asset 2 Hence, w1=w2=0.5 Portfolio Return; 0.5*15+0.5*12=13.5% Portfolio Variance=(0.5^2)*(10^2)+(0.5^2)*(8^2)+2*0.5*0.5*8=45 Portfolio Standard Deviation=Square root of Variance=(45^0.5)= 6.708204 We can see, the risk of portfolio as measured by Standard Deviation has reduced significantly to 6,7 whereas the assets in the portfolio had standard deviation of 10 and 8 Risk / Return ratio of the portfolio=6.7/13.5=0.496 Risk/Return ratio of asset1=10/15= 0.666667 Risk/Return ratio of asset2=8/12= 0.666667 Risk return ratio of the portfolio is lower WHY INVEST IN DIFFERENT INDUSTRIES TO DIVERSIFY? Return of same types of assets are highly correlated. Suppose, if you invest in 10 different Technology Companies, you may not be able to reduce risk, because all the companies will have similar return and highly correlated. We have seen in the equation of Portfolio Variance, one factor=2 w1*w2*Cov(1,2) If there is high correlation between return of asset1 and 2, the Covariance(1,2) will be high . Hence this factor 2w1w2Cov(1,2) will be high. As a result portfolio standard deviation will be high and diversification will not serve any purpose. Hence, in order to get benefit of diversification, we need to invest in different type of industries so that the correlation between different assets are low. Consequently, the portfolio risk (measured through standard deviation) is low. Solution There is an old saying “Do not put all eggs in one basket” Why? Because risk is high.By keeping eggs in different baskets, we reduce risk We try to do same thing through diversification. By investing our capital in different assets , we try to reduce risk. Diversified folios reduce the risk and also the rati.

(IEP or individual educational plan is an official document which carries the information depicting the personal/specific educatinal goals of children with special needs. It is not only a document, but refers to a protocol/programme which clearly demarcates the specific needs of a student. It has some features such as specilization, personalized, validity, usability as a shared document, information about requirement of a specific teacher/mentor or subject expert etc.) Answer 17: The statement is true. Technically, based upon the physical, physiological and psychological development of children, the age group of 6-11 has been globally accepted as the time of adolescence for growing children. This age group is associated with discrete phsycial growth (puberty), psycholgoical growth (feelings, emotions etc) and physiological growth (activation of reproductive organs).

Question 1 answer is A Global trade allows wealthy countries to use their resources - whether labor, technology or capital - more efficiently. Because countries are endowed with different assets and natural resources (land, labor, capital and technology), some countries may produce the same good more efficiently and therefore sell it more cheaply than other countries. If a country cannot efficiently produce an item, it can obtain the item by trading with another country that can. This is known as specialization in international trade. Question 2 answer is C All options are correct Question 3 answer is D Revenue tariffs are levied to raise money. Question 4 answer is D.(cannot promote third world development, unless governments offer some incentive for importing from third world economies). Question 5 answer is A Question 6 answer is C Solution Question 1 answer is A Global trade allows wealthy countries to use their resources - whether labor, technology or capital - more efficiently.

Precipitation hardening, or age hardening, provides one of the most widely used mechanisms for the strengthening of metal alloys. The fundamental understanding and basis for this technique was established in early work at the U. S. Bureau of Standards on Duralumin. The importance of theoretical suggestion for the development of new alloys is clear from the historical record. At the end of the 19th century, cast iron was the only important commercial alloy not already known to western technology at the time of the Romans. When age hardening of aluminum was discovered accidentally by Wilm, during the years 1903 -1911, it quickly became an important commercial alloy under the trade name Duralumin. The strength and hardness of some metal alloys may be enhanced by the formation of extremely small uniformly dispersed second-phase particles within the original phase matrix in a process known as precipitation or age hardening. The precipitate particles act as obstacles to dislocation movement and thereby strengthen the heat-treated alloys. Many aluminum based alloys, copper- tin, certain steels, nickel based super-alloys and titanium alloys can be strengthened by age hardening processes. In order for an alloy system to be able to be precipitation-strengthened, there must be a terminal solid solution that has a decreasing solid solubility as the temperature decreases. The Al-Cu (Duralumin is an aluminum alloy of 2XXX group) phase diagram shown in Figure 1 shows this type of decrease along the solvus between the and + regions. Consider a 96wt%Al – 4wt%Cu alloy which is chosen since there is a large degrease in the solid solubility of solid solution in decreasing the temperature from 550°C to 75°C.

Protists are beneficial to the ecosystem in generating oxygen as they are photosynthetic & single celled in aquatic system result in higher dissolved oxygen finally other trophic levels are in equilibrium Some protists are natural scavangers & profoundly promote \"decomposition of natural organic matter & dead bodies\" therefore nitrogen balance in the ecosystem Some protist are harmful to the ecosystem and they cause disease to various animal and humans result in ecological imbalance in trophic levels of food web Economic importance of protists: Bio-medical importance of protists: Ecological importance of protists: Ques-4: Green algae: These are the algae, which were originated predominantly from the endosymbiotic cyanobacteria, and these algae possess both plastids and chloroplasts for photosynthesis to perform their nutrients synthesis. Volvox is multicellular green algae and possesses cell differentiation as an evolutionary reproductive adaptation. The cells are associated with flagella outside for motility and vacuoles & chloroplasts inside. They mediate cell –to- cell communication through sensory perception obtained from “eyespot” finally neighboring cells join through “cytoplasmic strands” that promote cell –to-cell communication. Recent research has illustrated that cellular adhesion molecules (Algal-CAMs) are found in multicellular Volvox. However, the bulk transport has not observed in the Volvox, a primitive feature still yet to develop in them. Brown algae are the algae, which possess secondary chloroplasts as their functional units to perform their photosynthesis and these algae are commonly originated from the endosymbiotic red algae. Examples are diatoms. Phylogenetic relationship with land plants: Red algae do not possess property of photosynthesis & as they do not contain green pigments Ques-3: Outer coverings: Sphingolipids Pellicle Phospholipids & glycolipids Solution Protists are beneficial to the ecosystem in generating oxygen as they are photosynthetic & single celled in aquatic system result in higher dissolved oxygen finally other trophic levels are in equilibrium Some protists are natural scavangers & profoundly promote \"decomposition of natural organic matter & dead bodies\" therefore nitrogen balance in the ecosystem Some protist are harmful to the ecosystem and they cause disease to various animal and humans result in ecological imbalance in trophic levels of food web Economic importance of protists: Bio-medical importance of protists: Ecological importance of protists: Ques-4: Green algae: These are the algae, which were originated predominantly from the endosymbiotic cyanobacteria, and these algae possess both plastids and chloroplasts for photosynthesis to perform their nutrients synthesis.

Now a normal O2 molecule has 12 electrons in the valence shell so, O2+ has 11 electrons in its valence shell. The first two go in the s2s and the next two go in the s*2s. Now two go in the s2p. Now thats 6 of the electrons. 4 electrons go in the p2p level and the remaining one goes in the p*2p level. Now count that up and the bond order is 1/2 the number of bonding electrons minus antibonding electrons: Order = 1/2 (8 - 3) = 5/2 Solution Now a normal O2 molecule has 12 electrons in the valence shell so, O2+ has 11 electrons in its valence shell.
