EA & JB 2 Identifying Neisseria sicca INTRODUCTION Bacteria are microorganisms constituting a large domain of prokaryote. They are typically a few micrometers in length and have a number of shapes ranging from spirals to rods and spheres. Bacteria are known to be among the first forms of life to appear on Earth, and are present in almost all habitats. They inhabit water, soil, radioactive waste, acidic hot springs, and Earth’s crust…

III. RESULTS AND DISCUSSION III.1 A. dorsata and T. itama bee bread composition Laboratory analysis of A. dorsata bee bread showed that percentage of protein reached 13.82% (wet weight) and 19.96% (dry weight), lipid 7.80% (dry weight), fiber showed a value of 3.38% (dry weight) and 44.52% (wet weight). All of components in A. dorsata bee bread are placed in the range given by Compos et al., (2008) (Table 1). Table 1. Detailed composition of A. dorsatabee bread (dried mass). Main components…

Within past few years, obesity has badly struck the people of all ages. Amid busy lifestyle and hectic routines, the use of processed food has been terribly increased due to which most of the youth is currently facing the problem of obesity. While gaining weight is a no-hassle job, losing weight is certainly an uphill task. If you are facing the issue of unhealthy weight gain and want to get rid of the unwanted bundles of fats, this is the right time for you to make right choice. Obesity can…

Comparisons: Effect of crushed vs. whole tablet: The crushed tablet reacted faster because its surface area is smaller, allowing the particles to react faster with the water. The crushed tablet also produced frothy bubbles all over the water, whereas the reaction (bubbles) of the whole tablet was primarily around the tablet in the water. Temperature effect: The reaction was extremely slow in the cold water as molecules do not move as fast in cold water. Once you increased the temperature you…

Citrate tubes, and made a zigzag pattern on the slant, lightly inoculating with a needle and incubated them all at our optimal temperature. The following lab we will watch the slant for any color change and growth. The following lab date we had a Phenylalanine Agar slant and inoculated heavily doing a zigzag motion and the lab class after that we added 2 or 3 drops of 12% ferric chloride solution to the tube and observed for color change. The reaction we were looking for should have happened…

Introduction As the field of nutrition has developed over the years, it has become common practice for recreational and elite athletes to use diet and supplementation to enhance their training adaptations and performance due to competition in sport increasing and demanding more from the athletes to reach above and beyond to optimise their natural abilities. Due to the fact being, protein is essential to promote muscle growth, repair damaged cells and tissues, synthesise hormones and for a…

The benefits and risks of the scientific method of genetically modifying crop species Since the emergence of agriculture over 10,000 years ago, humans have been altering the genomes of the crops they produce in order to increase the crop quality in many ways, with fruit size and palatability being two obvious examples. Whether this occurred incidentally through the techniques used to cultivate the plants or intentionally through artificial selection, humans have created strains of domesticated…

The protein insulin is unique in many ways. Insulin is considered to be a hormone and also a protein. The word insulin is derived from Latin origins. Insulin was the first protein to have its sequence determined, and this was discovered by Frederick Sanger. Dorothy Crowfoot Hodgkin determined the spatical conformation soon after (Warburg, 2015). It is very important to understand how proteins work because they are essential to our health. Without proteins our bodies would not be able to form…

1. In your own words, define what is a mutation? Abnormal inherited or acquired permeant alteration in the sequences of the nucleotides of the deoxyribonucleic acid of an organism may or may not change organism phenotype, it occurs with a frequency of less than1% among a population. 2. Are mutations bad or good for you? Justify your answer in either case Mutations could be good, bad, or may have little or no effect. Beneficial mutations: Some mutations if they happen they have a positive…

As the results show, the increase of caffeine caused the mouse to complete the obstacle course in a slower time than without any caffeine. What does this really mean? The caffeine had a detrimental effect on the mouse’s cognitive and motor skills. In humans, low amounts of caffeine can be very beneficial by increasing alertness, improving concentration, and boosting overall energy. However, high amounts of caffeine cause adverse reactions, such as anxiety, restlessness, insomnia, elevated heart…
