Experiment for the measurement of carbon dioxide and oxygen concentrations and their functions during the act of breathing. Introduction: Humans‚ like all living organisms need‚ O2 in order to live‚ they take the necessary O2 from the atmospheric air. The O2 is transferred from the blood to all cells of the body and serves for oxidation of nutrients for example glucose. By oxidize the nutrients released energy‚ which is necessary for the functions of the human body. During oxidation produces

English Studies 102 Baba’s Gifts by Jenny Robson and Nomthandazo Zondo 1. The third person narrative voice has been used. The narrator is focalising through one particular‚ which is the main character‚ MaNdlovu. The readers see everything through her. “MaNdlovu looks about the yard and yes‚ it is clean.” 2. MaNdlovu has to tell her husband that they must start using protection (condoms) during sexual intercourse‚ as Dlamini works in the city‚ and spends most of his time there‚ which MaNdlovu

structure of the enzyme is mainly dependent on the active site and variable groups. Extreme temperatures or extreme pHs can alter the structure of an enzyme. Enzymes function to lower the activation energy to break the bonds. They achieve this by putting stress and pressure on the bonds or creating a microenvironment for the substrate. Enzymes are regulated by inhibitors or activators and can be inhibited by the products of the reaction‚ called feedback inhibition. Enzymes are catalytic proteins;

AP Biology August 23‚ 2012 Egg Osmosis Lab Definition of osmosis: The diffusion of water across a selectively permeable membrane from high to low concentrations Hypothesis: If I place an egg in vinegar‚ then the outer layer of the egg is going to become slimy and look like rubber. It will also become larger and bubbles will form on and around the egg. Hypothesis: If I place an egg in corn syrup‚ then the egg will become small and the outer layer will not look like rubber any longer. Day one:

Activity: 1. Get 1 bag of M&M’s. 2. Guess how many M&M’s are in your bag of M&M’s. Write it down. That is your hypothesis. (DO NOT OPEN BAG) 3. Open your bag of M&M’s and answer your questions (data collection/experimentation) 4. Also‚ be sure to count the total number of M&M’s in your bag and the number of each color M&M in your bag. Fill in the following information as you work: Question: Hypothesis: Repeat this experiment 2 more times. Fill in Table:

the DNA form in a nucleus when a cell isn’t undergoing mitosis (ie when a cell is in interphase)? The term for the DNA form in a nucleus when a cell isn’t undergoing mitosis is known as chromatin. 4. Why is mitosis important for multicellular organisms? Mitosis is important for multicellular organisms for many reasons. For an example‚ one reason is that wounds and cuts can be healed and repaired by adding new cells in the cell division

∆x x Figure 1.1: The slope of a line (usually given the symbol m) is the ratio of the change in the y value‚ ∆y to the change in the x value‚ ∆x. We define the slope of a straight line as follows: Slope = ∆y ∆x v.2005.1 - September 4‚ 2009 1 Math 102 Notes Chapter 1 where ∆y means “change in the y value” and ∆x means “change in the x value” between two points. See Figure 1.1 for what this notation represents. Equation of a straight line Using this basic geometric property‚ we can

Diffusion and Osmosis Through Dialysis tubing We did this experiment to test the diffusion of different substances through dialysis tubing. We used what we knew about diffusion to make predictions on what we thought the mass of the dialysis tubing to be after submerging them for 30 mins and we knew that diffuse occurs from highest concentration to lowest concentration. Since the dialysis tubings are filled with different substances than what they are being put into then they should all gain
