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

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

Khanya Ramey Tuesday Nov. 24 Intermolecular Forces Intermolecular Forces Lab II. Goal: The central goal of this experiment is to depict the intermolecular forces of four different properties of solubility‚ evaporation‚ viscosity‚ and boiling point. The reason for achieving the goal is so we can further understand solubility‚ Evaporation‚ viscosity‚ and the boiling point of liquids. III. Experimental procedures In this Lab there were four different stations to experiment with‚ my partner

Effects of Alcohol‚ Caffeine‚ and Temperature on the Heart Rate of Daphnia magna Joseph Ezra Gallo BY124L MW 8:30-11:30 Introduction Ectothermic animals are animals whose body temperature is affected by their surroundings. This means that if the environment is cold the animal will be cold. If the environment is warm the animal will be warm. This is because the animal doesn’t have the capability of regulating its body systems to keep a constant body temperature. When an ectothermic animal is

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:

The concept is very similar to sudden expansion in pipe flow‚ except that hydraulic jumps occur in open-channel flow. At

9/16/14 Physics 01L Density Abstract This experiment was conducted in order to determine the density of the Aluminum metal samples provided in the lab. Specific tools such as the vernier caliper and balance scale were used to measure and record the values found. Given that density is a measurement of mass over volume‚ both of these quantities would have to be determined experimentally‚ prior to proceeding with the calculation of the density‚ for each of the

Rachel Bohnenberger Professor Van Doorn ENVS 150-002 27 April 2015 GMOs Lab Report Introduction As the population of Earth increases exponentially‚ so does the demand for more food. One of the solutions to the question of how more food can be produced is Genetically Modified Organisms‚ or GMOs. There is an ongoing debate about whether or not GMOs are more beneficial or harmful to society. Some of the benefits to GMOs are: growing plants‚ such as corn‚ that are resistant to weeds and pests‚ larger

Determining the Catalytic Properties of the Enzyme Peroxidase Extracted from a Turnip Under the Conditions of Temperature‚ pH‚ Boiling and Competitive Inhibitors By Robin Caserta BIO 101 September 30‚ 2013 ABSTRACT The enzyme‚ peroxidase‚ extracted from a turnip was tested for its efficiency in binding to its substrate and its stability under several conditions. To do this‚ we tested effects on peroxidase activity‚ first‚ with different amounts of the enzyme‚ next at temperatures of
