iron-deficiency [13]. This is because polyphenols found in coffee and teas are known to be major inhibitors of iron absorption [13]. Masala tea also known as black tea and in masala tea there is tannis that inhibit absorption of iron [13]. These include chlorogenic acid‚ which is found mainly in coffee‚ cocoa and some herbs [13]. Summary from Healthline website‚ the polyphenols in coffee and tea inhibit iron absorption by up to 90% [13]. The more polyphenols you consume‚ the more they may inhibit

Introduction: The purpose of this lab is to use staining techniques and biochemical testing to identify an unknown bacteria using Bergey’s manual. Bergey’s manual of Systematic Bacteriology is a dichotomous key primarily used to identify a bacterial species. Biochemical tests are used to differentiate different species of bacteria. These tests are effective in determining the characteristics of the microbe being tested. Such characteristics include citrate utilization‚ gelatin hydrolysis‚ nitrate

horrible acts go on‚ we think to ourselves “How can someone be capable of doing this?”. Well the answer is mix of Monoamine Oxidase‚ or better known as “The Warrior Gene” and abuse. In this paper I will explain what the Warrior Gene is‚ how physical and emotional abuse affects it‚ and what it means for our Criminal Justice System today. So what is Monoamine Oxidase? Monoamine Oxidase breaks down important neurotransmitters that happen in our brain. Some of these neurotransmitters include serotonin‚ dopamine

of them. Among so many types of chocolates‚ dark chocolate contain the most antioxidant. New research published in the open access journal Chemistry Central Journal demonstrates that chocolate is a rich source of antioxidants and contains more polyphenols and flavanols than fruit juice. According to Stibich (2009)‚ dark chocolate is made from cocoa which contains flavanols‚ a type of flavanoid. Flavanoids are naturally-occurring compounds that occur in plant food. They act as anti-oxidants and help

Thirdly‚ genus Vibrio would show positive oxidase test. But‚ upon repeating the oxidase test for 5 times‚ a negative result was obtained. Moreover‚ there was no growth in the TCBS agar which is a selective media for Vibrio genus. Therefore‚ the bioluminescent bacteria isolated‚ could not be either Vibrio Fischeri or
