Christine Otieno Estimating Osmolarity of plant Cells(potato and celery)by percentage change in weight Using different sucrose concentrations Introduction The purpose of this experiment was to estimate Osmolality of plants cells i.e. Potato and celery by converting the observed change of weight in different sucrose concentrations. The hypothesis assumes that the solute concentration of the plant samples would be indirectly proportional to the weight; there would be decrease

ABSTRACT The effect of different levels of radiation was determined using four set-ups-10kR‚ 30kR‚ 50 kR‚ and the control (no radiation). The four set-ups were observed for nine weeks and growth (in cm)‚ germination‚ and survival rate was measured. Results showed that at the right level of radiation level (10 kR)‚ radiation have a positive effect on the plant growth and has the same germination and survival rate from the control set up. The 30 kR set up and 50 kR set up are relatively smaller

Soren Chemicals Case Study 1. What is the addressable market size for Coracle? Is the first-year goal of $1.5 million sales reasonable? Answer: Currently there are 3 major players in the residential pool clarifier market‚ Keystone chemicals‚ Kymera and Jackson Laboratories as well as several distributors who are diluting and private lebeling Soren’s Kailan MW for residential use. Soren’s Jen Moritz estimates that these players have between 15 and 20 percent (15-20%) of the residential pool market

“Physiological regulation of fluid compartment volumes and chemical composition is critical for normal cell function.” It is important that the human body has the ability to maintain a constant internal environment referred to as homeostasis (Waugh and Grant 2010). Claude Bernard was a 19th century French physiologist who first discovered the concept of homeostasis. But it was Walter Cannon‚ a 20th century American physiologist who devised the word “homeostasis” (Marieb and Hoehn 2007). Temperature

Osmosis coursework Aim: To investigate the effect of different concentration of a sugar solution on the amount of osmotic activity between the solution and pear pieces of a given size. Define osmosis: Osmosis is a net movement of water/ solution molecules from a region of high concentrated area to a region of lower concentrated area through a semi-permeable membrane which lets smaller molecules such as water through but does not allot bigger molecules like glucose to pass through. The molecules
