research 1 Watery rose apples as vinegar Abstract The study was done to make use of the waste rose apples. Two kilograms of rose apples were gathered and washed. Then‚ they were squeezed and the extracted juice was fermented by adding two teaspoons of yeasts. After two weeks‚ it smelled like vinegar but is tasteless. Five weeks after‚ the product was already vinegar. It is concluded then that rose apples (or tambis in bisaya) could be processed and make into vinegar. Background of the study The

The synopsis of this article relates to how a group of researchers from Riverside‚ California have revealed a molecular mechanism that directs the chance and role of cells during the process of animal development. The researchers’ discovery shows remarkable findings that are promising in the advancement of cancer and stem-cell research. The hypothesis of this article relates to even though each individual cell contains the complete DNA code‚ only small portions of this DNA code are activated. Therefore

Johannes Kepler and Rene Descartes that the speed of light was infinite‚ having the ability to travel at any distance immediately. A notable physicist named Galileo Galilei was one of the first scientists to ponder this phenomenon of light‚ and how to determine the speed of this unknown. In order to do so‚ Galilei formulates an experiment with an assistant. While standing on one hilltop‚ and his assistant standing on another farther away‚ both held a lamp that could be uncovered and covered whenever

HOW DEMAND DETERMINES OUTPUT IN THE SHORT RUN Typically‚ firms that supply intermediate goods such as steel rods or other inputs let demand not price determine the level of output in the short run. To understand this idea‚ consider an automobile firm that buys material from a steelmaker on a regular basis. Because the auto firm and the steel producer have been in business with one another for a long time and have an ongoing relationship‚ they have negotiated a contract that keeps steel prices

NaOH and Determination of Unknown Acid KEYWORDS: quantitative analysis‚ titration‚ buret‚ endpoint‚ standardization‚ half-equivalence point‚ calorimetric titration‚ potentiometric titration ABSTRACT: The concentration of sodium hydroxide was determined by colorimetric titration‚ and the identity of an unknown acid was determined by potentiometric titration. In the first titration‚ a strong acid standard‚ potassium hydrogen phthalate (KHP)‚ was used‚ to determine the concentration of a strong

Luck Determines How You Think and Play Julie Camacho EN 111‚ Section 15 Professor Sarmiento February 12‚ 2015 Luck Determines How You Think and Play Golf seems like a pretty easy sport for it does not require any intense exercise of such. What most people do not know is that golf deals with concentrating and managing anxiety. A person playing golf may build anxiety from the fear of making a wrong move as the audience gazes at him or her. The golfer may react a little differently if he or she were

Acid Rain and the Effects of our Monuments and Churches The two controlled experiments that I chose to do‚ do not involve trees or plants‚ which I think a lot of people will be doing. I wanted to explore the devastation that acid rain does to our historic monuments and beautiful churches. My first controlled experiment is based on the Statue of Liberty. It is made of copper so I am using pennies in my experiment. (nps.gov. n.d.) My observation is that acid rain corrodes metals
