Evaluate the positive and negative effects of globalization in China Globalization, which is the process of enabling financial and investment markets to be operated widely and internationally, usually refers to the increasing global relationships of culture, people, and economic activities (Simon. J, 2002). It is generally used to represent economic globalization including the global distribution of the production of goods and services, through reduction of barriers to international trade such as export fees, and import quotas. â€Å"Globalization has become one of the most talked about debates of the past 10 years and as been the subject of numerous books and videos and the cause of many global demonstrations in most of the major cities all†¦show more content†¦And with the process of reformation and opening and in-depth socialistic modernisation, China is becoming increasingly closer to the world’s whole economy. To be sure, globalization has three main positive effects on China. First of all, globalization contributes to attracting foreign investment for the opening to the whole world. For western countries, China’s development has provided a huge market for them. At present, China has become one of the world’s biggest investment countries via foreign trade, and basically it is a country with complete inflow of capital. Second, globalization helps with the expansion of external trade. With more than 20 years’ efforts, external trade has become an important increasing point of China’s domestic economy. Overholt (2005) commented that about a quarter of economic growth every year depends on the external trade with China. Third, globalization is helpful with absorbing rural surplus labour force (Dauderstadt M, 2005). So far, China is still a less-developed country with a large population. In the process of industrialisation, large rural population and surplus labour force are a serious problem to solve all the time. However, in recent years, the success of a great many township enterpr ises and the development of joint ventures have brought a chance to transfer rural labour force. Compared with creating opportunities, globalization inevitably brings some challenges as well. Some of them are already evident, and some haveShow MoreRelatedAbstract.

Answer: Part 1 Virus Bacteria Fungi ta protoctista Not living in environment, reproduce within host Single celled with spherical, rod or thread like Multicellular, heterotrophic organism Single celled or multicellular Does not respire Prokaryotic, have cell wall, cell membrane and DNA as genetic material and does not have cell organelles (Abbas, Lichtman Pillai, 2012) Eukaryotic, have cell membrane and defined nucleus Eukaryotic, contains nucleus and other smaller organelles, genetic material is packed in envelop Have only genetic material RNA/DNA Reproduce via binary fission Can reproduce sexually or asexually Reproduce via binary fission, asexual reproduction Eg. HIV, Hepatitis B Eg. E. coli, Streptococcus sp. Eg. penicillin Eg. Plasmodium falciparum Conditions necessary for bacterial culture in laboratory A growth medium with necessary nutrients is the primary requirement of bacterial culture. Usually agar gel is used, as it contains all things required by bacteria. Commercially produced media with all nutrients are used in the laboratories along with sterile water. Some organisms have special needs which are met by adding additional nutrients in the medium prepared. Most of the organism requires moderate conditions for grow including moderate temperature, 37C, neutral pH, around 7 and oxygen concentration in the case of aerobic organisms (Asthagiri Arkin, 2012). Safety precaution include washing hands, sterilizing with alcohol after using pathogenic culture, disinfecting work area with alcohol after use, working with culture under UV cabinet, using gloves, using micropipettes, clear labeling and discarding waste materials after disinfecting it (Talaro Chess, 2012). Figure: Bacterial culture (Source: Jain, 2012) Role of antibiotics in controlling bacterial disease Antibiotics are the secondary metabolites of microorganisms which either kill bacteria or block their growth while present in the culture. The bacteriostatic organisms usually blocks the growth of organism, withdrawal of antibiotic revive the function of the organism. In contrast, bactericidal antibiotic works by killing organism. They do not affect host cells (Jain, 2012). A number of factors can hamper the function of bacteria. One of them is the bacterial resistance. The resistance toward an antibiotic can be transferred to bacteria by transferring R plasmids. Figure: Antibiotic controlling bacterial growth (Source: Laskin, Sarialani Gadd, 2012) Method of transmission 1. Bacterial disease Campylobacter infection is caused by the Campylobacter sp. bacteria via contaminated food. The route of transmission is oral in this case. It causes inflammatory dysentery, diarrhea to the patient, causing dehydration. Fluoroquinolone, tetracyclines are effective antibiotic treatment against the infection (Laskin, Sarialani Gadd, 2012). 2. Viral disease Influenza virus causes flu with runny nose and related symptoms. As it is an air borne virus, the route of transmission is nasal route. It can be treated via anti viral drug treatment, which also includes antibiotic usage. 3. Parasitic disease Plasmodium falciparum is a parasite which uses two hosts in their life cycle. The parasite completes most part of its life cycle in anopheles mosquitos salivary gland and transmitted to human body by bite of infected mosquito and causes malaria. Treatment includes administration of chloroquine, mefloquine (Talaro Chess, 2012). Part 2 Natural immunity Natural immunity refers to innate or non specific immunity which is raised by body after encountering the physical and cellular barrier of defense system. Artificial immunity Artificial immunity is induced by the exposure of the patient to a vaccine, substance containing the inactivated pathogen. Active immunity When a person is exposed to a live pathogen, the resulting natural immunity of body immune system against the pathogen is known as the active immunity (Male, 2012). Passive immunity Passive immunity is induced by the antibodies which are ready-made. The active humoral immunity when transferred to the antibodies administered outside of the body, the passive immunity is developed. Role of T and B cell in immunity The T and B cells are the key players of adaptive or acquired immune system. After encountering any foreign particles, the T lymphocytes are the stimulator of adaptive and B cells are the stimulator of humoral immune system. B cells engulf the pathogens and present through MHC complex which is then bound by specific T cells and stimulates the differentiation of more T cells, on the other hand, secreted lymphokines influence differentiation of B cells into plasma and memory B cells. Plasma cells act in active immunity (Male, 2012). Polio vaccine provides immunity against the Polio virus. Two kinds of vaccines are available in market. IPV is inactivated polio vaccine in which the organism is injected in an inactivated state, against which the antibody is generated in body. OPV is oral polio vaccine, in which the live vaccine is injected in attenuated state; the organism has lost the capability of infection. IPV has been reported to immunize 99% people after 3 doses and OPV has been reported to protect 95% individual after 3 doses (Stansfield et al., 2012). Figure: Role of B and T cells in Immunity (Source: Jain, 2012) Part 3 Forensic screening Screening of genetic disease Prenatal screening Forensic screening is used for detecting criminal offenses or catastrophe victims and used for legal purposes. DNA foot printing is used in this case which uses DNA sequences from victims or accused persons sample Genetic screening is done for detecting genetic mutation, RFLP, AFLP, SNP are used for diagnosing genetic disease Prenatal testing is done for identifying any kind of genetic mutation in fetus. It is beneficial as it helps to detect the actual offensive person and helps in legal work It helps to identify genetic disorder which is beneficial if identified at first stage Pros of this testing is getting awareness of any detrimental disease of fetus Sometimes ethical issues raises regarding the forensic screening as it deals with personal information of suspect or victim (Jain, 2012) Sometimes it raise ethical issue if the stem cell therapy is necessary Sometimes it brings ethical issues, if the fetus is diagnosed to have genetic disorder, in that case the ethical concern is regarding the survival of fetus Flowchart of Insulin production by RDT Figure: Insulin production in RDT (Source: Rajagopal, 2012) Moral and ethical issues of Recombinant DNA technology The moral and ethical issues arise regarding the recombinant DNA technology arises while working with human genome. The modern techniques in RDT are capable of changing human characteristic at the gene level which is changing the natures decision. Changing human hereditary characteristic is an ethical issue, everyone would try to get the best characteristics and there would be issues regarding superiority, especially while working with stem cells. Thus human cloning has been banned (Jain, 2012). Reference List Abbas, A., Lichtman, A., Pillai, S. (2012).Cellular and molecular immunology. Philadelphia: Elsevier/Saunders. Asthagiri, A. Arkin, A.
