Raudah P. Mangbisa Grade VIII-Nilo VIRUS A virus is a small infectious agent that replicates only inside the living cells of other organisms. Viruses can infect all types of life forms‚ from animals and plants to bacteria and archaea. Characteristics: Like living organisms‚ viruses contain nucleic acids and proteins. Inside living cells‚ viruses can reproduce‚ but not by the process of mitosis like most living cells. Viruses lack some characteristics of living organisms. Outside of living cells‚ viruses are

This is because gold is very resistant to bacteria. Bacteria are microscopic single-celled organisms. Bacteria are prokaryotes‚ meaning the entire organism consists of a single cell with a simple internal structure. The DNA of a prokaryote is neatly packed in the nucleus. The bacterial DNA floats freely in a twisted threadlike mass called the nucleoid. Gold is unaffected by almost everything. The only materials that can affect gold are man-made. Since bacteria are a natural organism‚ it cannot react

Hypothesis 3: Mel Giedroyc will use tag questions‚ empty adjectives and politeness strategies in order to appear more welcoming on her radio show I hypothesised that on her radio show‚ Mel Giedroyc would use much more stereotypical ‘women language’ than her male host Bush as well as Nick Grimshaw. This is supported by Robin Lakoff’s gender deficient model which proposes that women speak in such a way that benefits men and makes them look good. She also developed the ‘politeness principle’ in which

Within linguistic theory‚ two extreme positions concerning the relationship between language and thought are commonly referred to as ’mould theories’ and ’cloak theories ’. Mould theories represent language as ’a mould in terms of which thought categories are cast ’ (Bruner et al. 1956‚ p. 11). Cloak theories represent the view that ’language is a cloak conforming to the customary categories of thought of its speakers ’ (ibid.). The doctrine that language is the ’dress of thought ’ was fundamental

Aims The purpose of the two experiments was to determine the fundamental effects that temperature has on the growth and survival of bacteria. During the first experiment five different bacterial broth cultures of Escherichia coli‚ Pseudomonas fluorescens‚ Enterococcus faecalis‚ Bacillus subtilis and Bacillus stearothermophilus were individually incubated at temperatures of 5‚ 25‚ 37‚ 45 and 55°C for one week in an aim to distinguish the effect temperature has on growth and survival of the five different

diseases can kill many people that are drinking water on the tap water and mostly on the drinking fountain; people might drink on a drinking fountain which is dirty because of the different people that are drinking and spiting their saliva on to it‚ bacteria can easily contaminate the water that is coming out from the drinking fountain. Bacteria’s are also found everywhere in the surroundings; even the sink in our home might have bacteria’s because of the dirty place‚ and in the school also have bacteria’s

Application of lactic acid bacteria There are four major categories for the current uses and applications of LAB: food‚ cosmetic‚ pharmaceutical‚ and chemical applications. In food industry Recent years the interest increased in using LAB by using bacteriocin-like inhibitory substances (BLIS) because of their potential use as a natural antimicrobial agent to enhance the food safety of food products and increase the nutritional values of the food. Foods that fermented by LAB such as cheese

The Life Cycle Hypothesis Formulated by Franco Modigliani of MIT. 1. The theory basically says that individuals plan their consumption and savings behaviour over the long term with a view of allocating incomes in the best possible way over their entire lifetimes. 2. This implies different marginal propensities to consume out of permanent income‚ transitory income (temporary) and wealth. 3. The basic idea is that individuals will spend the different incomes differently with a view
