Daniel Thompson 10/31/14 NT1110 Unit 7 Assignment 1 Complementary Metal Oxide Semiconductor‚ or CMOS‚ is a widely used type of semiconductor. CMOS semiconductors use both NMOS(negative polarity) and PMOS(positive polarity) circuits. Since only one of the circuit types is on at any given time‚ CMOS chips require less power than chips using just one type of transistor. This feature makes them convenient for use in battery-powered devices such as laptops. Personal computers also contain a small amount

Joshua Annan Biology Section-04 Diffusion and Osmosis December 14‚2012 Alexis‚ Adiba‚ Elliot and Joey Purpose: The purpose of this lab is to get a better understanding of osmosis and diffusion in molecules. We will do this by studying different solutions and how they move through the permeable membrane. Hypothesis: The three different possible predictions were the lab were that the mass would stay the same‚ the mass will increase‚ or the mass will decrease

I am going to investigate osmosis when potato is placed in different concentrations of sucrose. I am aiming to witness osmosis in 5 different concentrations of sucrose. I will use 5 varying concentrations so that I have a wider spread to compare the results‚ and check that I don’t have any anomalies Prediction Osmosis is the process of diffusion of water molecules from a weaker solution into a stronger solution‚ through a semi permeable membrane. The tiny pores in the membrane

Osmosis Practical Report Introduction: To determine the biological changes that occur to potato cores over a period of time in different solutions of sucrose and to relate these changes to the phenomenon of osmosis. Method: We soaked several discs of potato cuted using a cork borer with around 1 centimeter of diameter and 2 milimeters of lenght into sucrose solutions with a different range of concentrations from 0 to 1.0M. Then we weighed all the potato

Osmosis Lab Report The essential focus of the experiment was to acquire data for the mass change resulting from osmosis in order to determine the carbohydrate solution of the carrot cells. The carrots were a vegetable used within the experiment with a carbohydrate solution around .5 M. The hypothesis is if there are carrots in different carbohydrate solutions then there will be a percent change in mass. The carrots have large vacuoles that hold water‚ this allows the mass to increase when the hypertonic

things move from a higher concentration to a lower concentration‚ it is known as diffusion. As long as diffusion is permitted to go on‚ equilibrium will be reached. Equilibrium is when two areas have reached equal concentration levels. The egg in this lab will have water and substances diffusing though it in and out. The direction‚ in which things diffuse‚ depends on the type of solution the egg is placed in. A hypertonic solution isa solution that is outside the cell and it has lower free water molecule

land of Bangladesh. In last few decades‚ the demand of potato is increasing rapidly. As a developing country‚ the people of Bangladesh are not so affluent. That’s why they prefer potato to rice or wheat. The demand of potato is thus increasing as it is cheaper than the other two horticultural product rice and wheat. Last year‚ the production of potato is massive. But‚ that huge production makes a little impact on the price level of potato. The price at the point of production is relevantly low
