Cross-linking Changes the Properties of a Polymer Integrated Science Sample SBA Task Practical Related Task – C1 Osmosis in Living Tissue Student Handout (Version 1) Purpose To determine the water potential of potato tissue. Background When two solutions with different concentrations are separated by a selectively permeable membrane‚ osmosis takes place. Water will pass from the side with higher water potential to the side with lower water potential. When a plant tissue is immersed in a solution

World Population can be stopped if we work together. Since early times the population of our world has rose from the inventions of medicines and new technology. With population rising towards ten billion we need to begin to start thinking about preserving resources. The rising population can be controlled if we improve education‚ start a two child rule per family‚ and provide family planning guides too young adults in rural countries. Improving education throughout the world will help stall the

Human Population Human Population As we look around us‚ we can actually see how things are becoming over crowded. Lines at the store‚ driving on the highways and how schools classrooms are getting bigger. This is all due to the human population intensifying. We add about a million and half people to our world population every week! What effects is this having on our environment? Is it hurting our water systems and changing our climates? What can we do as a society to help or change

through microtubules and histones. DNA in the nucleus is loose and not well defined into chromosomes because it is usually tightly coiled‚ but in the interphase nucleus the chromatin exists in two forms: loosely coiled form called euchromatin and tightly coiled formed called heterochromatin. These two types become more coiled to form the chromosome at the time of cell division. DNA is a bit loosely coiled in the euchromatin its bases are then available for transcription. When it is in the form of

were placed on a study board were the long and l short axis of the sediments were measured by the use of large ruler and tape measure then the samples were recorded. The velocity at these localities two and three were obtained by measuring the velocity (speed) of the river. This was done by two students standing in the river from top to bottom. A bottle filled with water was then placed in the river to float. A distance was measured at 15m with a tape measure‚ the time the bottle took to float

OVER POPULATION “Whether we accept it or not‚ this will likely be the century that determines what the optimal human population is for our planet. It will come about in one of two ways: Either we decide to manage our own numbers‚ to avoid a collision of every line on civilization’s graph – or nature will do it for us‚ in the form of famines‚ thirst‚ climate chaos‚ crashing ecosystems‚ opportunistic disease and wars over dwindling resources that finally cut us down to size” – Alan Weisman
