zmosis The IB Lab Report Measuring osmosis 1. Introduction My experiment is about osmosis on a potato and if or the quantity of salt affects osmosis. I would do the experiment with 5 potatoes cut into squares all the potatoes weight the same so the weight can`t be a variable the I put the potatoes on 5 different plastic cups with different amounts of salt and then I weight them again to see if the quantity of salt affected the osmosis of potatoes 1a. Research question ¿Does the quantity

MARGINAL AND ABSORPTION COSTING Marginal costing is a technique in which production units are valued at marginal cost of production and fixed costs are written off as period costs. It follows that‚ stocks are valued using only the variable cost of production whereas fixed costs are treated as relating to the period and must be taken off in total. Management accounting is based on marginal costing. TERMINOLOGY USED. Gross contribution: Is the difference between sales value and variable costs

Bioinformatics Lab Report Hypothetical Phylogenetic Tree: Using a cladistic approach‚ we constructed a hypothetical phylogenetic tree of many different plant taxa by comparing their morphologies. We first decided to sort the various types of plants into groups based on morphological features. After sorting these plants into five different groups we began to determine how the plants differed from eachother in the group and what features set them apart. From this we started to create

Lab Report Enzymes (must be typed) Name: Amanda Gallegos Date: 2/15/15 Section: BIOL 101GL What is the Hypothesis of this experiment? (3 points) -The highest temperature will affect the reaction rate of enzymes. What is the dependent variable? (1 point) -Change of rate/product/color/absorbency. What is the independent variable? (1 pt) -The temperature. Explain in detail the procedure that you followed (including amount of substrate‚ enzyme etc‚ and the whole procedure including incubation times)

OTHER TYPES OF THE NUCLEAR TECHNOLOGY APPLICATIONS THAT HAVE THE POTENTIAL TO EVOLVE IN SOUTH AFRICA AND WHY THIS WOULD BE FEASIBLE South Africa as a developing country and is one of the world leader in supplying food and raw material. It has very a lot of arable land and large reserves of natural resources. The warm climate favours the production of most crops and livestock which is in demand by the population. The country’s economic backbone lies between the performance of the mining and agricultural

bile ducts. The digestive enzymes and the bile acids will allow to transform the chyme‚ liquid including food pre-digested by the digestive juices coming from the stomach. Absorption: For its activity‚ the body will absorb certain elements such as carbohydrates‚ lipids‚ proteins‚ electrolytes‚ vitamins‚ as well as water. Absorption of the products of digestion is mainly in the small intestine‚ and mainly in the duodenum and jejunum. -The tongue is an accessory organ anchored to the floor of the mouth

Introduction In this lab we had to design a system that would test if changing the mass‚ angle of release and length would have any effect on the period of a pendulum. Hypothesis As the length‚ mass and angle of release change‚ the period (T) will change for each one of these factors.

Biosphere Lab Report A biosphere can be defined a lot of different ways. Our interpretation of a biosphere is the area in which life can be contained within. In the case of the earth‚ it means as high as a bird can fly and as deep as fish can swim in the ocean. A biosphere is a closed system that has a constant flow of energy between the organisms living within it and it needs nothing outside of itself but sunlight to continue to be sustained. At the University of Arizona‚ they attempted to build

LAB REPORT HYPOTHESIS 1: Plants transpire the most when the environment has light and less humidity JUSTIFICATION: Water evaporates more readily because light stimulates the opening of the stomata and photosynthesis would occur. HYPOTHESIS 2: Transpiration would occur the second most when there’s light and lots of humidity. JUSTIFICATION: The light would allow photosynthesis to occur and the stomata to open but little if any diffusion of water out the leaf would occur. HYPOTHESIS 3:

Enzyme Lab Report Introduction The objective of this experiment was to determine if changes in pH or temperature affected the activity of enzymes‚ specifically the enzyme sucrase. Enzymes are protein molecules that act as biological catalysts to increase the speed of the reaction or to lower the activation energy of that reaction. However‚ the activity of an enzyme can be affected by physical factors such as pH and temperature because these factors alter the structure of the enzyme (Freeman‚ 2011)
