    Beetroot experiment

    The effect of alcohol concentration on the cell membrane Abstract: In this experiment I found out that as the concentration of the alcohol was increased so did the colour intensity of the solution. This is because the higher concentration of ethanol‚ results in more damage done to the cell membrane‚ resulting in leakage of red pigment from the cell. If the membrane is damaged more‚ more red pigment will leak out of the membrane and into the ethanol. Hypothesis: The higher the concentration

    Introduction To determine the effects of stressful experimental treatments on living membranes we are going to examine how fresh beets roots react when they are exposed to different temperatures. Membranes are an important feature of plant cells and they act as a barrier that separates the interior of the cell from the external environment (Campbell 133). They organize specific chemicals and reactions into specific compartments within the cell. Generally‚ cell membranes consist of phospholipids bilayer

    out how the permeability of a beetroot membrane cell is affected by ethanol. To do this we will investigate different concentrations of alcohol (10-70%) and measure the absorbance using a colorimeter to show us how much juice has leaked out. Hypothesis I predict that as the concentration of ethanol goes up‚ the permeability will increase as the ethanol will slowly dissolve more phospholipids (lipid bilayer) and so more anthocyanin (the beetroot juice) will leak out of the membrane. So at 10%

    endothelial barrier strictly maintains vascular and tissue homeostasis‚ and therefore modulates many physiological processes such as angiogenesis‚ immune responses‚ and dynamic exchanges throughout organs. Consequently‚ alteration of this finely tuned function may have devastating consequences for the organism. This is particularly obvious in cancers‚ where a disorganized and leaky blood vessel network irrigates solid tumors. In this context‚ vascular permeability drives tumor-induced angiogenesis‚ blood flow

    The poem “The Mouth” written by bpNichol is littered with ambiguity. You could pick any line in any stanza and find something with a double meaning. In the second stanza‚ Nichol writes: “You were never supposed to talk when it was full. It was better to keep it shut if you had nothing to say. You were never supposed to shoot it off. It was better to be seen than heard.” Besides the obvious oral fixation he has‚ what does he mean when he says this? It seems as though he has been silenced before in
