I. INTRODUTION The worldwide the bacterial community includes billions of microorganisms. Microbiologist and other scientists are constantly working of identifying species and classifying them by morphological, biochemical and molecular tests. This is valuable to the medical community, as some of these microorganisms are pathogens, but also to other industries such as pharmaceuticals, foods and drinks production, ecological, agriculture and biotechnology as humans have used bacteria for years…

the detriment that this severe pathogen brought to American Chestnuts, researchers and environmentalists have sought ways to relieve the problem, most notably through the study of the role of the mycovirus CHV-1, or Cryphonectria hypovirus, as a biological control agent, as previously discussed (7). Cryphonectria hypovirus naturally evolved with both Asian and European Chestnut…

The simple but revolutionary organism Drosophila melanogaster has intricate properties that are studied to find its relations with human genes. Not only is D. melanogaster a model organism for its rapid growth, inexpensive culturing, and easy modifications, the Drosophila can provide more in-depth scientific analysis that can solve human diseases. The model organism D. melanogaster is studied to find ground-breaking research in neurology, sleep, cancer, and drug discovery. The multivariable…

when it is that season of the year when flowers are scattered everywhere. Flowers are sunshine, food and medicine for the soul. A flower is sometimes called a bloom or blossom, it is the only reproductive structure found in flowering plants. Its biological function mostly it is to outcome reproduction through a mechanism of the amalgamation of sperm with eggs. They may go through what is called outcrossing and selfing. In addition to easing the reproduction of flowering plants, humans use…

plant. (Campbell, pg. 175). Inside the chloroplasts, thylakoids contain pigments such as chlorophyll that play major role in photosynthesis. (Citovsky, Lecture 10). Photosynthesis are composed of light reactions and Calvin cycle. Light reactions required the light to initiate photoexcitation. Photoexcitation happened when the light strike on chlorophyll, the electron will be excited and transferred around the antenna pigment molecules. Electrons will then be transferred to a reaction-center…

both reducing sugars and amino acids at high temperatures while dry cooking. The carbonyl group of the sugar interacts with the nucleophilic amino group (amine; -NH2) of the amino acid peptides or proteins to eliminate a molecule of water, a brown pigment, called “melanoidin” is formed after polymerization and odor and flavor of molecules resulted. In the process, hundreds of different flavor compounds are created. These compounds in turn break down to form yet more new flavor compounds, and so…

30 minutes. Placing it in hot water to speed up the process. • Drain out the leaves leaving the coloured water. • Cut filters into strips slightly longer than the jar itself and place in the jar • Leave it for about an hour and watch as the colour pigments in the leaf separate to reveal the hidden colours Integrated Experiences: Health: Discuss what the digestive system does and how it is similar to the photosynthesis process Creative Arts: Have children add pressed flowers and leaf rubbings…

condensation of primary amines and carbonyl compounds.It was first time presented by the Hugo schiff (Cimerman et al, 2000). Schiff bases are one of the most important class of organic drugs widely used in variety of different fields such as analytical, biological, and inorganic chemistry.The schiff bases heve been designed to synthesize more and more novel lead molecules possessing least toxicity with highest efficacy.Schiff bases have importance since the last decade that it pulled the…

the beet in each concentration of each alcohol for 15 minutes. We then found the concentration of Betacyanin in each alcohol solution by measuring the absorption in the spectrophotometer. The higher the absorbance, the higher presence of Betacyanin pigments in the alcohol solution. My results for the 1-propanol solutions have an ascending absorbance from 0.001 to 0.364; however, this is after omitting the 40% alcohol concentration that has an unusual absorbance of 0.220.…

in the late 17th century. Pamela R. Willoughby describes Linnaeus’ scientific observations in her book “The Evolution of Modern Humans in Africa: A Comprehensive Guide”. Willoughby states, “Linnaeus made a bold move to suggest that humans had a biological connection to other animals” also that “Homo sapiens should be separated into geographic groups according to the ‘races’ recognized during his lifetime.” Many philosophers and scientist expanded upon h Linnaeus’ ideas in this time period.…
