Salt pregnancy test positive and negative

Are you wondering if you are pregnant or not? Or Are you suspecting to be pregnant due to an unprotected sex you had lately? Here is a simple way to check by yourself if you are pregnant or not. It requires only salt. You do not have to visit a doctor or any health personnel. It is as simple and easy as ABC. Salt is considered to be a very clean chemical compound since it is crystalline in nature. This characteristic nature of salt makes it a very good and popular chemical compound for testing if an individual is pregnant or not. Also, its chemical content is highly effective in detecting a hormone known as human chorionic gonadotropin (hCG) which is normally found in the urine of pregnant ladies or women. This hCG (human chorionic gonadotropin) I am talking about is often released during pregnancy by the placenta. Things you would need for the salt pregnancy test: 1. A transparent glass bowl (you can use any other bowl but most people prefer transparent glass bowl in order to

Gram staining well explained (UPDATED)

What is Gram Staining? Anthrax gram stain Gram staining is a common technique used to differentiate two large groups of bacteria based on their different cell wall constituents. The Gram stain procedure distinguishes between Gram positive and Gram negative groups by coloring these cells red or violet. Gram positive bacteria stain violet due to the presence of a thick layer of peptidoglycan in their cell walls, which retains the crystal violet these cells are stained with. Alternatively, Gram negative bacteria stain red, which is attributed to a thinner peptidoglycan wall, which does not retain the crystal violet during the decoloring process. READ ABOUT: Acid-Fast Stain- Principle, Procedure, Interpretation and Examples How Does Gram Staining Work? Gram staining involves three processes: staining with a water-soluble dye called crystal violet, decolorization, and counterstaining, usually with safanin. Due to differences in the thickness of a peptidoglycan layer in the

Study: Coronavirus Can Survive Higher Temperatures

The new study reveals the coronavirus may be strong enough to withstand higher temperatures and won't die from it. Coronavirus Can Survive Higher Temperatures Previously, experts hoped that the coming warmer months of summer can help eliminate SARS-CoV-2, which is the novel coronavirus strain behind the current pandemic. Based on previous similar pandemics and the typical cycle of the yearly flu season, their hopes made sense since these viruses usually start infecting people during the latter half of winter and start fading away when the summer comes. As such, experts were hoping that even if summer does not outright kill the new coronavirus strain, they were hoping that summer would slow it down, at least until we develop a definitive vaccine for it. Unfortunately, a new study reveals that the virus may be strong enough to withstand the summer's warmer and higher temperatures. This is the conclusion that researchers at the University of Aix-Marseille in France

Kenyan Man Arrested With Weed Chapati

A Kenyan man surprised authorities after being caught feasting on a rare chapati made of cannabis flour. This is an indirect consumption of the drug. Many smoke or eat a famous cookie also made from the cannabis flour. Marijuana, which is deemed illegal by the Kenyan government, has realized a significant growth of users among youths. READ ABOUT: Did you know Kenya Has the Strictest Plastic Bag Ban in the World Marijuana users in the country have been crusading for its legalization.

Carbohydrate (glucose) Fermentation Test: Uses, Principle, Procedure and Results

The carbohydrate fermentation test is used to determine whether or not bacteria can ferment a specific carbohydrate. Carbohydrate fermentation patterns are useful in differentiating among bacterial groups or species. It tests for the presence of acid and/or gas produced from carbohydrate fermentation. Basal medium containing a single carbohydrate source such as Glucose, Lactose, Sucrose or any other carbohydrate is used for this purpose. A pH indicator (such as Andrade’s solution, Bromcresol purple (BCP), Bromothymol blue (BTB) or Phenol red) is also present in the medium; which will detect the the lowering of the pH of the medium due to acid production. Small inverted tubes called Durham tube is also immersed in the medium to test for the production of the gas (hydrogen or carbondioxide). The term fermentation is often used to describe the breaking down or catabolism of a carbohydrate under anaerobic conditions. Therefore, bacteria capable of fermenting a carbohydrate

Phenol Red Fermentation Test – Principle, Procedure, Uses and Interpretation

Fermentation media are used to differentiate organisms based on their ability to ferment carbohydrates incorporated into the basal medium.Phenol Red Broth Medium with various added carbohydrates serves as a differential medium by aiding in differentiation of various species and genera by their ability to ferment the specific carbohydrate, with the production of acid or acid and gas.The carbohydrate source can vary based on test requirements. The common broth media used are:Phenol Red Glucose BrothPhenol Red Lactose BrothPhenol Red Maltose BrothPhenol Red Mannitol BrothPhenol Red Sucrose Broth Objective To determine the fermentation reactions of pure cultures of microorganisms. Principle Carbohydrate fermentation is the process microorganisms use to produce energy. Most microorganisms convert glucose to pyruvate during glycolysis; however, some organisms use alternate pathways. A fermentation medium consists of a basal medium containing a single carbohydrate (glucose, lacto
