The results above show group wajaisha from class 1a obtained different results compared to my group. Wajaisha’s group used pH 4 and my group also used pH 4. The results that we obtained were after five days we had 35 cells present however wajaisha’s group obtained 42 cells after five days. My group obtained a value of 28000000 per litre and wajaisha’s group obtained 33600000 per litre. Our results may have been slightly different due to us not being able to record the number of cells present on the

take place in cells. Enzymes can be found in both liver and potato. They provide a site where reactants can be brought together to react. These reactants are called substrates that fin into the enzyme. The changing of heat‚ surface area‚ chemicals‚ and pH will denature the shape of the enzyme‚ not allowing it to do its function. Testing on peroxidase- an enzyme- will be done on an animal enzyme (chicken liver) and a plant enzyme (potato). For testing Hydrogen Peroxide (H2O2) will be poured over the enzymes

Ranking Salt Solutions by pH 6-2: Ranking Salt Solutions by pH In this assignment you will be asked to rank aqueous solutions of acids‚ bases‚ and salts in order of increasing pH. This is most easily done by first identifying the strong acids that have the lowest pH‚ the strong bases that have the highest pH‚ and the neutral solutions that have a pH near 7. The weak acids will have a pH between 1 and 6 and the weak bases between 8 and 14. The exact order of weak acids and

density of water is 999.97 kg/m³ . Variables: Manipulated Variable Method of controlling Volume of water The volume of the water is measured by dropping water into the cylinder. Random error such as parallax error would occur. So I took the measurement three times. 0.00001m³ of water is added to the cylinder each time. . The experiment is conducted for volume of water of 0.00001m³‚ 0.00002m³‚ 0.00003m³‚ 0.00004m³‚ 0.00005m³‚ 0.00006m³‚ 0.00007m³‚ 0.00008m³‚ 0.00009m³ and 0.00010m³. Responding

ADI Lab Report Every living thing is made up of cells. All cells have some part in common. Some multicellular cells are highly specialized and carry out some very important functions. One of the special cells are red blood cells‚ their functions‚ transporting oxygen from the lungs to the cells in the body. Red blood cells look like little discs. Red blood cells can change their shape‚ this ability allowing them to squeeze through capillaries without breaking. Our task is to Design and carry out an

Introduction and Purpose: This lab focuses on how weight affects the time it takes for a rotocopter to fall from a drop height of 1 and 2 meter(s) respectively. The primary goal of this lab is to investigate and explain the relationship of these two factors. During the process of conducting this experiment‚ learning to design a lab will also be achieved. Research Question: What is the effect of weight on the time it takes for a rotocopter to fall from a drop height of 1 and 2 meter(s)? Variable

themselves. ⋆ Their presence does not affect the end product. ⋆ They only need a small effort to change a large amount of substrate. ⋆ Enzymes are very specific and usually only speed up a single reaction. ⋆ Their rate of activity depends on the PH of the substance‚ the temperature of the substance and the concentration of both the substance and the enzyme. An enzyme fuses with its substrate and this makes an enzyme-substrate complex. Once this reaction has occurred‚ the complex will break
