    weigh less due to osmosis. Our null hypothesis was: If the pH level of a solution is either acidic or basic‚ then it will have no effect on the weight. The independent variable was the different solutions of different pH values. The dependent variable was the weight of the potato‚ which was measured in grams. The baseline of this experiment is the weight of the potato when in the milk solution because milk has a neutral pH. The controls in this experiment are that each sample had

    “Of all the arts‚ abstract painting is the most difficult. It demands that you know how to draw well‚ that you have a heightened sensitivity for composition and for colors‚ and that you be a true poet. This last is essential." -- Wassily Kandinsky. Abstract Art is art that is not a precise demonstration of a form or object. This depiction can be diverged in many ways including the shape‚ color‚ and form. The artist takes the object and then either simplifies it or exaggerates it using these

    concentrations on the activity of osmosis in plant tissue. Background scientific theory: Plants exchange gases (CO2 and O2) in maintaining vital respiratory processes and in carrying out photosynthesis; they absorb certain minerals and sugars so to use as a source of energy and eradicate wastes in order to maintain specific requirements for survival. Large amounts of water are absorbed by root hairs and are then distributed across the cells of plants by the process of osmosis; water being essential to

    Egg Osmosis Lab Introduction What is osmosis? Osmosis is a very important part of biology. It is the spontaneous passage of water or other solvents through a semipermeable membrane. A semipermeable membrane is one that blocks the passage of dissolved substances. Osmosis occurs when there is an imbalance of solutes outside of a cell versus inside the cell. A solution that has a higher concentration of solutes than another solution is said to be hypertonic‚ and water molecules tend to diffuse into

    Diffusion is one of several transport phenomena that occur in nature. A distinguishing feature of diffusion is that it results in mixing or mass transport‚ without requiring bulk motion. Thus‚ diffusion should not be confused with convection‚ or advections‚ which are other transport mechanisms that utilize bulk motion to move particles from one place to another. In Latin‚ "diffundere" means "to spread out". There are two ways to introduce the notion of diffusion: either a phenomenological approach

    Osmosis is a passive movement of water through a selectively permeable membrane moves from an area of higher concentration to an area of lower concentration. In this lab‚ we can determine the direction of diffusion of small molecules by measuring the diffusion of small molecules through dialysis tubing. This tubing acts as a selectively permeable membrane‚ and allow to pass larger molecules slowly. Introduction: Cells have kinetic energy and it causes the molecules of the cell to move around

    class average‚ there is evidence that osmosis did occur in the bags. The largest change in mass was in the 1.0M sucrose bag the mass went from 12g initially to 14.2g‚ this gained 2.2g‚ an 18.3% change in mass for the group data over the duration of the experiment. The 0.2M bag went from 10.2g to 10.9g a 6.9% change in mass; the 0.4M bag went from 12.1g to 12.2g .83% change in mass; the 0.8M bag went from 10.9g to 12.2g and an 11.9% change in mass. During osmosis water diffuses‚ going from an area

    The aim of the sixteenth of November experiments was to observe how three different solutions with various sucrose concentration influenced osmosis in relation to three onion cells and the impact on the cells structure. A small square of a red onion skin (membrane) was observed under a microscope at high power (X40) magnification. The observation showed a large number of onion cells. The structure of one onion cell had a general rectangular shape with a developed cell wall‚ which gives the rectangular

    Introduction to Abstract Expressionism Abstract Expressionism started in America as a post World War II art movement. It was the first art movement that arose from America and put New York at the center of the art world. The term Abstract Expressionism was first applied to American art in 1946 by art critic Robert Coates. It is most commanly said that Surealism is it’s predecessor because of the use of spontaneous‚ automatic and subconscious creations. Abstract Expressionism gets its name from

    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
