Abstract In this lab‚ we tested the effects of temperature on fungal amylase and bacterial amylase (Aspergillus oryzae and Bascillus Licheniformis). We used 4 different temperatures in Celsius 0‚ 23‚ 58‚ and 89 for both fungal and amylase. For 10 minutes‚ every 2 minutes we would use 3 drops of each amylase and mix it with iodine to observe the presence of starch at each temperature. We conducted this experiment for both bacterial and fungal amylase. Results were reached based on the color of the

Temperature Effects on Radish (Raphanus sativus) Root Development Abstract Several studies have been conducted to establish how temperature‚ seed germination‚ and root growth are related. Because temperature plays a main role in many growth processes‚ we decided to focus on how it affected root growth. Radish (Raphanus sativus) seeds were chosen due to their ability to produce a distinct bulbous tuber‚ and their relatively short growing time. Three test groups were placed under different temperature

experiment to find the optimum temperature and pH for starch on amylase. The experiment was carried out in one day. The researcher and a partner did the experiment based on a lab manuel from class. Data was collected from the experiment and to be displayed on graphs. Then the optimum pH and temperatures were to be calculated based on the findings. The hypothesis was disproved due to the optimum pH of 5 but the other findings supported the hypothesis of the optimal temperature being 45 degrees Celsius.

Chapter 6 Measuring Vital Signs Unit 1: Temperature‚ Pulse‚ and Respiration UNIT RATIONALE Important indicators of your patient’s/client’s health status are known as vital signs. Vital signs give you information about breathing‚ body temperature‚ and the heart. They are a good indication of how well the body systems are functioning. As a health care worker‚ you need to observe patients whenever you are near them. Your knowledge of vital signs and how to measure them helps you know when to report

METHODOLOGY After formulating the hypothesis that the molecular weight affects the rate of diffusion‚ three different kinds of substances --potassium permanganate (KMNO4)‚ potassium dichromate (K2Cr2O7) and methylene blue (C16H18N3SCl)‚ were used to test the validity of the hypothesis. Potassium permanganate is an inorganic chemical compound which is in violet liquid form; potassium dichromate is an orange inorganic chemical reagent and methylene blue is a chemical compound commonly used for staining

Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration. Because of the selective permeability of the membrane only water and other very small particles (iodine) can be diffused through simple diffusion. The solution out of the dialysis tubing had a higher distelled iodine concentration of solutes (iodine + H2O) than did the starch solution. So iodine move into the cell and react with starch molecules to formed starchiodine‚ the blue compound

different temperature on the cell respiration. Introduction： Cell respiration is the controlled release of energy from organic compounds in cells to form ATP‚and then release waste products. The process of cell respiration can take place in the presence or absence of oxygen. In either case‚the first stage of cell respiration is glycolysis.The effect of temperature on cell respiration mainly depends on the effect of temperature on of enzyme activity.Generally speaking in a certain temperature range

The effect of temperature on the permeability of cell membranes Introduction For my coursework‚ I intend to assess how temperature affects the plasma membrane of a cell. For this I will use the cell of a beetroot. Background What is a cell membrane? The cell membrane‚ also called the plasma membrane is a semipermeable lipid bilayer which is the surface of all cells that surrounds the cytoplasm. The membrane is called a bilayer as it has a double layer of phospholipids. Within the cell membrane

The effect of Temperature on the Xylem of Tomato Plants Question: How does temperature affect the Xylem in Tomato Plants? Introduction: Throughout this experiment I will be testing the size of the Xylem in Roma tomato plants when exposed to different temperatures. I will be placing six Roma Tomatoes in six different area which will each be in different temperatures. After three weeks of constantly watering the tomato plants with blue dyed water I will cut the plant from the root and examine
