Iodine is a test for starch while Benedict’s solution is a test for reducing sugars. When solution A is tested by benidicts test‚ the clear blue solution changed to a little reddish and brick red precipitate is formed.this result show that solution A is a reducing sugar. When carried out iodine test with solution A‚ the colourless solution remain unchanged . this tell us that starch is absent is solution A. When solution B is tested with Benedicts test‚ the clear blue solution remain unchanged‚ we

Introduction: Living‚ microscopic‚ unicellular organisms can be identified as microorganisms. Fungi‚ Protista‚ Bacteria‚ and Archaeans are four kingdoms in the phylogenetic tree of life that consist of microorganisms. Amongst these microorganisms the prokaryotes were the first ones to arrive through evolution. The rest of the life forms as we see them evolved from these simple creatures‚ prokaryotes. The smaller prokaryotes were swallowed by bigger prokaryotes setting the stage for the origin of

SOCIAL DILEMMS CRISCYNTHIA MCWILLIAMS INTRODUCTION TO SOCIAL PSYCHOLOGY DORIE RICHARDS FEBRUARY 18‚ 2013 Our perception of ourselves can be one of many but the most important of our perception is determined by our behavior. What we think about ourselves is who we become. If we think we are inadequate‚ we will begin to act that way. If we feel positive‚ we will act that way. The trail forward towards

Osmosis and Diffusion During the past few weeks in my Ag Biology class we have been learning about and reviewing both osmosis and diffusion. We did two different labs‚ one on osmosis; the other on diffusion. The first lab we did was our diffusion lab. We learned that diffusion is moving something from an area of high concentration to a low concentration. We were showed that Mio and other flavor drops perform diffusion when put in water as an example. For the lab part we put a mixture of starch

Ellen Ryan Biology IA Task G1 Investigation into the biodiversity of organisms at different heights on a rocky shore. PART (1) Ellen Ryan Introduction This experiment was carried out in order to better understand Hong Kong’s ecology and biodiversity‚ specifically focusing on field-based whole organism biology in an area with little human interferences. Method 1. Lay a horizontal transect on the mid-shore (1.75m) 2. Repeat for high-shore (2.25m) 3. At regular intervals of 1m

Osmosis: How fast can you move? The Rate at which Osmosis Occurs when Exposed to Various Toxicities Within the human body many things are occurring at all times. Without these small‚ seemingly insignificant processes all human life would cease to exist. One of the aforementioned activities is Osmosis‚ or the movement of water across a selectively permeable membrane eventually establishing equilibrium on both sides of the concentration gradient (Freeman 90). During this specific experiment involving
