Rationale The big issue is that I want to see if chemical reactions will happen faster if they happen at different temperatures. So, I will see if iodine solution and starch solution will react faster if they are at room temperature, at 40 degrees and if they are cold. So, I will be recreating the Iodine Test Background Research: The...

Abstract Heavy metals beyond the threshold concentration in nature are often considered as phytotoxic. They cause damage to environment by affecting the soil fertility, biomass, crop yield and the human health. There are various approaches put forth by researches, but the most cost-efficient emerging remedy is been seen as phytoremediation; where the plants are itself involved partially or substantially in...

ABSTRACT Salts are essential for life which primarily composed of sodium chloride (NaCl). It has been widely used in various ways such as food seasoning, food additives and even in beauty line for cosmetic products. However, through industrialization and human activities, the concentration of radioactive materials and toxic elements in salt might exhibit above the legal limit amount, resulting hazardous...

ABSTRACT The effect of salt stress under the two salinity levels and control (0, 100mM, 150mM) on three varieties of wheat SASSUI, SEHAR, MARVI was conducted. The data showed that the NaCl salinity stress significantly affected the growth of wheat seed arrtibutes by reducing the shoot and root length. Regarding the germination, the maximum germination was found in genotype SASSUI...

“All substances are poisons; it is the dose that makes the poison.”, Philippus Aureolus Theophrastus Bombastus von Hohenheim stated. Heavy metals are commonly characterized as metals with a high toxicity level in high concentrations generally with high atomic numbers, atomic masses, or densities, and those metals are located on the 3rd-15th groups and through the 4th-6th periods. Moreover, heavy metals...

Inquiry-based learning (IBL) is a student-centered Pedagogic strategy, a process that is ideally led by students. This strategy aims to teach students science by doing it, to attain conceptual change, or accommodate new knowledge, as Jean Piaget's theory of cognitive development claims. To achieve that, students work collaboratively. Build on previous knowledge and one another’s work engaging in active self-directed...

Introduction Steel often interacts with hydrogen in a variety of ways, especially because steel is used typically in structural components. Today these applications may vary from bridges to the transportation of natural gas, making the knowledge of this interaction useful [1]. Due to its high chemical reactivity, hydrogen can diffuse into the surface of steel and then appear ionically or...

Diffusion and barriers affect the impact diseases have significantly. Diffusion is the spread of people, ideas, cultural practices, etc. from one place to another. Barriers are usually associated with something negative, the closing of something. But in the case of diseases it may have positive effects. When barriers such as distance did not allow humans to travel long distances, the...

Introduction While coacervates are not alive, they are good representations of how early life may have formed from simple organic substances under the right conditions, which eventually led to the formation of prokaryotes. Under suitable conditions, life-like structures can form naturally from relatively simple materials. In the 1920’s, a scientist named Oparin predicted that biological molecules would form in an...

Introduction The purpose of this procedure is to study the impact of various levels of salt in relation to the enzyme catalase during the breakdown of hydrogen peroxide. Catalase is important to the body because it breaks down hydrogen-peroxide from its toxic form (H202) into water and oxygen. Salt, or sodium-chloride, is a necessary electrolyte in maintaining homeostasis within the...

Introduction Between the years of 1960 and 2000, the presence of obesity in adults aged 20 to 74 years old in the United States increased from 13.4% to 30.9% (Bravata, 2003). There were an estimated 325000 deaths due to obesity and a staggering number of $39-$52 billion dollars in direct health care costs to treat obese individuals (Bravata, 2003). According...

Abstract The purpose of the investigation was to examine the correlation of enzyme production in response to the evolutionary impact of AMY1 gene copy numbers in individuals. Based upon research obtained in previous studies, there was an assumed positive correlation between gene copy numbers and the production of salivary amylase protein levels in mg/mL. Variances in copy numbers can be...

Abstract pH is a logarithm used to measure the alkality and acidity of food. Meat of high quality has ultimate pH at the range of 5.4–5.6, Meat quality is significantly affected by preslaughter factors. The pH raw meat ranges from 6.10-6.71 while for processed ranges from 6.64-6.90. Meat with a pH above 6.2 tends to have tightly packed water-retaining fibres...

Mark Kurlansky, author of Salt: A World History, once claimed “salt is so common, so easy to obtain, and so inexpensive that we have forgotten that…salt was one of the most sought-after commodities in human history.” Rather than going through what salt is today, Kurlansky decides to recall the history of salt. The book cites the different events that occurred...

Electric or Hydrogen? Both sound like exemplary options, however, looks can be deceiving. Electric vehicles are vehicles that use electric motors as a source of propulsion, while hydrogen-powered vehicles use a fuel cell that uses hydrogen and oxygen molecules which react and form electricity. This electricity is used to run the electric motors. While both hydrogen and electric-powered cars have...
