Cells must move materials through membranes and throughout cytoplasm in order to maintain homoeostasis. The movement is regulated because cellular membranes‚ including the plasma and organelle membranes‚ are selectively permeable[1]. The purpose of an automatic flow of molecules is to create equilibrium on each side of the membrane. In order for molecules to pass through the membranes‚ there must be pores. The size of the pore determines what molecules can cross. Due to the size and polarity‚ only

COCONUT SUGAR ADDED WITH ANTI-FERMENATION AGENT – WHAT IS THE DIFFERENCE! Anti-fermentation agent made of lime‚ calcium hydroxide or sodium metabisulfite are openly and traditionally use by most coconut sugar producing countries. Adding Anti-fermentation agent is use as customarily use by coconut sugar processor if they will harvest the coconut sap every 12 hours like every 6:00 AM and 6:00PM. The advantages of using of anti-fermentation agents is they are able to used taller coconut trees at lower

Investigating the effect of different concentrations of glucose on the percent change in mass of Gummy bears according to their respective colours In this experiment osmosis is the main process taking place. Osmosis is the diffusion of water molecules of a solvent which pass through a semi permeable layer and in most cases are due to a concentration gradient meaning that the water molecules travel from an area of low concentration to one of higher concentration. In this investigation‚ gummy bears

Potato Batteries: Veggie power! Data and Analysis Background The battery was invented around 1800 by Alessandro Volta in Italy. It has become an indispensable part of modern life. Why are batteries so useful? Because they convert chemical energy into electrical energy. You can use this electrical energy to light a flashlight‚ to start a car‚ or to listen to your favorite music. We made a simple battery out of a potato by placing in it a zinc strip and a copper strip. At the zinc strip‚ the

To investigate the effect of variation in temperature on the permeability of cell membranes using fresh beetroot Aims In this investigation‚ you will subject fresh‚ washed beetroot discs to different temperatures to investigate the effect of temperature on the permeability of the plasma membrane. Overview The beetroot discs will be placed in distilled water at different temperatures. You will compare the intensity of the beetroot pigment that has leaked out from the cells subjectively and possibly

No Sugar‚ written by Jack Davis in 1985 is a social realist play that depicts the isolation and disempowerment of Aborigines during the 1930’s. Various dramatic conventions have been employed to highlight the negative effect of the Eurocentric‚ hypocritical and dominant ideologies of the Anglo-Saxon society on the Indigenous population. It depicts the struggle and

Therefore to sum things up‚ my hypothesis is when the Independent variable increases so will the dependant variable. Independent variable: - Surface area of potato Dependant variable: - Gas Controlled variable: - Equal size of potatoes used - Using measuring cylinder Equipment used: - Gas collecting kit - Potato - Stop watch - Test tube - Distilled water - Hydrogen
