This investigation tested the hypothesis: The rate of osmosis will increase as the temperature increases 2x2x2cm cubes of potato were weighed and then placed into 100mL of 10% NaCl solutions for 10 minutes. After 10 minutes the cubes were again weighed to determine the amount of mass that they lost/gained and thus get an indication of the rate of osmosis. The results collected showed that the rate of osmosis was highest in the 70°C solution and lowest in the 20°C solution

gills only allow them to take in oxygen from the water. The percentage of oxygen is the water is significantly lower than the amount of oxygen in the air. Fish have adapted to be able to filter oxygen from the water despite its low percentage. Gas exchange in fish occurs in their gills which is supported by a bony arch. Fish take water in through their mouths. Water enters via a fish’s open mouth‚ its opercula close and stop water from leaving before being forced through the gill filaments. Once the

The respiratory rate is a very important tool through which it is possible to recognise early signs of deterioration of a patient (Philip‚ Richardson & Maurice Cohen 2013‚ p. 570). Despite this‚ there is an increasing amount of cases in which healthcare professionals‚ nurses in particular‚ do not routinely assess and document this important vital sign correctly (Massey & Meredith 2010‚ p. 538). This essay will discuss the reasons why healthcare professionals are likely to omit assessing and documenting

experiment is to determine the rate law and the activation energy for the reaction between persulfate ion‚ S2O82-‚ and iodide ion‚ I-: S2O82-(aq) + 2 I-(aq) 2 SO42-(aq) + I2(aq) The rate law can be written as Reaction rate = (1) Where m and n are the orders with respect to S2O82- and I-‚ respectively‚ and k is the rate constant. Determining the rate law involves determining the values of m and n. The temperature dependence of the rate constant is given by (2)

The purpose of this practical is to investigate how the pulse rate of humans changes when they exercise. Someone who is physically fit can supply their muscles with enough blood‚ carrying glucose and oxygen‚ for an activity at a lower heart and breathing rate. The fitter you are the lower your resting heart rate. You and your classmates will be the humans investigated. SAFETY: If you know you have any condition that affects you doing exercise‚ please make sure your teacher knows before you start

Introduction The nation’s high unemployment rate is a result of a severe drop in demand for goods and services. It’s not a reflection of longer-term structural changes in the economy but rather cyclical changes in the economy. The demand for goods has been limited because of tight credit‚ decreases in government budgets‚ suppression of demand by consumers and foreign markets‚ and the inability by the fed lower interest rates. Even with the low level of interest rates the Fed is currently practicing a tight

The national unemployment rate fell to 4.4 percent in October the lowest level of unemployment since May 2001. This is a sign of unexpected strength in the job market. [The unemployment rate is based on a survey of households‚ rather than the survey of employers used to calculate the payroll number. Unemployment does not include full-time students‚ the retired‚ children‚ or those not actively looking for a paying job.] The unemployment level is defined as the labor force minus the number of people

The discount rate Main article: Discount rate The rate used to discount future cash flows to their present values is a key variable of this process. A firm’s weighted average cost of capital (after tax) is often used‚ but many people believe that it is appropriate to use higher discount rates to adjust for risk or other factors. A variable discount rate with higher rates applied to cash flows occurring further along the time span might be used to reflect the yield curve premium for long-term
