Scientists that i truly admire I have two scientists who I admire Thomas Alva Edison and Humphry Davy. Thomas Alva Edison is one of the best investors; Thomas Alva Edison was conceived in 1847 out of a residential community in Ohio. His instructors thought he was a moderate student, so his mom showed him herself, moving his enthusiasm for science. In 1869, subsequent to moving to New York, he enhanced a machine called the 'ticker'. It was utilized for handing-off data about the share trading…

Dr. James A. Peck, a clinical psychologist who specializes in addiction, offers the following lesson in brain chemistry: “Crystal meth forces dopamine and norepinephrine to be blasted through the brain, so when you stop using meth, there’s a definite effect on your brain, which creates the anhedonia. The jury is still out as to whether it is permanent. We do have P.E.T. scan studies showing that for some users, it takes up to two years for the brain function to return to where it was prior to…

Collection and Identification of an Environmental Bacteria to the Genus level Introduction: Bacteria can be found virtually anywhere, and interaction with these organisms occurs daily (Fitzpatrick & Allison, 2014). However, though the interaction between human and bacterium is continual, it is not always known what type of bacteria a person is coming into contact with. Therefore it is important to understand, and to have knowledge about, the characteristics of bacteria in our environment. As…

fatal. One of the major health issues that is associated with exposure to radioactive substances is cancer. The most common cancer that stemmed from the disaster at Chernobyl is thyroid cancer. Due to the high exposure of iodine-131 found in food, the thyroid gland accumulated iodine from the bloodstream, which in turn led to the increase in thyroid cancer (The Chernobyl Forum, 2006). But, according to World Nuclear Association (2015), other than thyroid cancer, many of the other health issues…

All cells are derived from pre-existing cells - through the process of meiosis and mitosis 4. In a multicellular organism, the activity of the entire organism depends on the total activity of its independent cells 3 Significance of technological advances to developments in the cell theory Assess the impact of technology including the development of the microscope on the development of the cell theory The development of cell theory has been heavily impacted by the improvement of technology. The…

deficiencies and to determine the nutritional and health status of children aged 6-59 months and women of reproductive age (pregnant and non-pregnant women aged 15-49 years). The micronutrients being examined include Vitamin A, vitamin B12, iron, folate and Iodine deficiencies and associated factors among the targeted population. Key indicators identified by the SLMS team comprise of anaemia and malaria…

thyroid gland is an endocrine gland located in the anterior part of the neck (Virtual Medical Centre, 2008). Cretinism is classified into two types known as Endemic Cretinism and Myxedamatous Cretinism. Endemic Cretinism is caused by insufficient iodine intake, and Myxedamatous Cretinism is mental detainment and causes…

While the birth rate increases approximately one percent every year, the death rate increases too. The united nation say’s that around twenty-one thousand people die every day due to hunger or hunger-related causes, the food just does not get to all the people around the world. World hunger is an old problem that has been around ever since the sixteenth century and possibly earlier than that. There is around eight hundred and seventy million people in the world that do not have enough food and…

potential. Water moves from areas of higher water potential (higher free energy and more water molecules) to areas of lower water potential (lower free energy and less water molecules). Water diffuses down a water potential gradient. Questions 1A 1. Iodine enters the bag because the substance begins to turn a dark purple color and the bag gets bigger. Glucose leaves the bag; we know this because we use a glucose indicator to find out if glucose seeped out. 2. The substances moved and out of the…

enzymatic activity and inconclusive or atypical results. Slight water residue was observed in the test tubes prior to use in the experiment, and may have contributed to the overall lack of enzyme activity (i.e. water may have diluted the enzymes). The iodine solution added to the spot plates just before the amylase-starch solution was added may have also contributed to the inconclusive results as it may have oxidized too quickly and the bond it should have formed with starch was not…
