My results and the graph indicate that as you add the caffeine to the daphnia‚ the eart rate of the daphnia increases for example the daphnia’s heartbeat is 120 without caffeine‚ however when caffeine is added it is increased to 168. My graph shows a positive correlation and the error bars are also very small which shows that the results have a small range which suggests that my results are accurate and reliable. I think that the experiment was conducted well however there may be some ethical issues

Osmosis investigation Aim: To investigate how sugar concentration affects the mass or size of a potato and find out the sugar solution. Introduction: Osmosis is the movement of water molecules across a partially permeable membrane form a region of high water concentration to a region of low water concentration until the concentration on both sides is equal. This means that osmosis is like diffusion involving water molecules. Osmosis occurs across a partially permeable membrane‚ with holes

Chemical reactions can happen slowly or fast. The speed of the reaction rate can be changed. Some of the factors that can affect the reaction rate are surface area‚ temperature‚ and concentration and pressure. Surface area is the exposed‚ outer layer of a solid. Increased surface area increases reaction rate because more particles on the surface of a solid come in contact with the particles of another substance. For example‚ if you place a donut stick into water‚ the donut will react slowly with

investigate the effects of temperature on the growth rate pine seedlings. Experiment 1 A batch of 60 pine seedlings (Batch I) was grown in a greenhouse under controlled temperatures. Ten plants were grown at each of six temperatures from 50 C to 300 C. These plants remained at their original temperatures 24 hours each day for two weeks. All other conditions were the same for all seedlings. The growth rates are shown in Table 1. Table 1. Growth rates for pine seedlings in Batch I Experiment II A

Managing cultural diversity in an organization i. Introduction The world is now on the way to reach with globalization‚ all the countries in the world try to share their labors‚ try to create their relationship‚ and they are all trying to work to together among the different nations.

Cultural diversity is a shared way of life of a number of people who have common knowledge of values‚ morals‚ beliefs or behaviors. In culture knowledge can be derived from experiences‚ attitudes‚ religion‚ different roles or skills. In cultural diversity there is a sense of behavior that has been learned from experiences or patterns passed through communication from one generation to the next. Sub-Culture is group within or smaller than a cultural group which has people of different ethnic background

One can predict that the tube with the highest concentration of yeast will produce the most carbon dioxide and will have the fastest rate of alcoholic fermentation. Results Two separate experiments were conducted to determine the effect of yeast concentration and pH level on the rate of fermentation. The first experiment involved the placement of different concentrations of yeast‚ glucose‚ and distilled water in four different tubes. Pipette pumps were

The effects of environmental temperature on respiration rates of mice were observed in this experiment. I hypothesized that when environmental temperature decreased‚ the respiration rate of mice would increase. I predicted that if environmental temperature decreased‚ the respiration rate of mice would increase. The respiration rate of the endotherm was measured using the Qubit/Vernier system and the S152 CO2 gas sensor‚ a device that measured the CO2 concentration in the air. The independent variable
