yellow colour disappears. Avoid excessive washing‚ as this may weaken the impregnation. After the last washing‚ discard supernatant‚ leaving about 0.1 ml of the sample. Add 0.01 ml of Mayer’s albumen glycerol solution and mix gently to avoid foaming. Incubate the cells in this solution for about 30 min. Transfer the precipitate with ciliates evenly on 2 or 3 grease-free cover glasses (24×24 mm) and distribute across the surface using a mounting eyelash or fine insect needle. Remove excess liquid carefully

destination the Gardenia Bakeries in Laguna where different taste of bread made. After we arrived in Gardenia‚ we wait for about 30 minutes because the accommodation of seats in the film showing was limited so they divide the students into two. So it’s our time to eat lunch‚ relax‚ taking pictures‚ nap and retouch. After 30 minutes the film showing started. We watched about 5 minutes about the history of Gardenia‚ Gardee‚ Gardenia’s mascot‚ was a very welcoming sight at the lobby. Turning-off cellphones

Title Experiment 17 Reaction Kinetics- Determination of the Activation Energy of the Reaction Between Oxalic Acid and Potassium Permanganate. Objective To determine the activation energy of the reaction between oxalic acid and potassium permanganate. Theory and Background Activation energy is the minimum amount of energy that is required to activate atoms or molecules to a condition in which they can undergo chemical transformation or physical transport. In terms of the transition-state

generation‚ and in every generation there is improvement in communication because of the advent of technology‚ but‚ “I fear the day that technology will surpass our human interaction. The world will have a generation of idiots” by Albert Einstein. Can really technologies make human become idiot? Actually‚ people become more creative in molding the thing that was invented before such as cellphones or mobile phones. As recent study in year of 2009 and 2018‚ the mobile phones was invented in the year of 1940s

BIOL2220 Lab 3: Hill Reaction Introduction In 1937‚ Robert Hill discovered that isolated chloroplasts can generate oxygen when they are illuminated in the presence of a suitable electron acceptor‚ even in the absence of carbon dioxide. This finding was a landmark in the study of photosynthesis because it established that the source of the electrons used in the light reactions is water. It also confirmed that the released oxygen is derived from water instead of carbon dioxide. In chloroplasts

Tips for Everyone wants privacy in their life and they often secure their things from others but what about your WIFI connection? You don’t want your neighbors or street boys use your internet connection as you are paying yourself and if they get access to the network they might have access to your browsing history and data you stored locally. So how do you secure your connection and block unwelcome visitors and stay away? It doesn’t require you to become IT professionals but simple things will secure

Abstract This experiment is to study the effect of temperature on the rate of reaction between potassium permanganate with oxalic acid. We used 2cm3 of 0.02M potassium permanganate and 4cm3 of 1M sulphuric acid into a test tube. In another test tube‚ we placed 2cm3 of oxalic acid. We placed the test tubes in a water bath at 40‚ 45‚ 50‚ 55 and 60oC respectively. When the solutions have attained these temperatures pour the oxalic acid into the acidified permanganate solution and recorded the time

Redox Reactions Reactions involving oxidation and reduction processes are very important in our everyday world. They make batteries work and cause metals to corrode (or help to prevent their corrosion). They enable us to obtain heat by burning fuels--in factories and in our bodies. Many redox reactions are complex. However‚ combustion and synthesis (from elements) are two ordinary examples which require very little description. Just a little more involved are the displacement reactions‚ with
