With Focus on the British Isles how in 50 years time will climate change effect plant productivity and biodiversity. http://www.pnas.org/content/104/50/19686.full Plant productivity is expected to be strongly affected by climate change within the next 50 years. Lobell et al. (2011) showed that climate trends since 1980 were large enough in many countries to offset a significant proportion of the potential increases in average crop yields due to technological advances‚ CO2 fertilization and other

Thermometer 1 roll of insulation tape Procedure 1. Wind the wire around the PVC pipe. Fix the ends of the wires to the insulation tape. Remove about 3 cm. of insulation from the wire using the tips of the paper knife. Measure the resistance of the wire using the ohm setting on the multimeter. 2. Connect the batteries in series using the jumper wires to produce 4.5 V. The ammeter‚ battery and wire wound around the pipe should be connected as shown in figure 1. 3. Record

Climate Change and the Effect on Endangered Species There are many problem in this world‚ every day an anomaly is done that affect the future of this planet. As history illustrate man has always wanted to expand his borders without laying site of what horror he left behind The urge to develop and expand the society has merely brought about the distraction of this planet. A trench has been dug so far off‚ that it’s merely impossible to ride that horse once again. In the last decade machine and

EFFECTS OF CLIMATE CHANGE ON HUMAN BEINGS AND HOW YOU CAN MINIMISE THEM Ever since the past century rainfall patterns have been so unpredictable‚ temperature levels have changed drastically and natural disasters have crowded over the entire earth. Life on earth is on great danger and no doubt that the world is drifting away little by little. Time and again‚ Climate change has been the root cause of all these events. It has threatened lives of human beings‚ wild animals both

The Effects of pH on Slime Mold Dg Nicole Harris BIOL181 – 059 1 December 2011 The theory that slime mold is attracted to acidic solutions was examined by the slime mold‚ Dg. Dg’s preference of pH was examined by using a variety of pH solutions in a petri dish. The data suggests that the growth of fruiting bodies observed in pH 9 was comparable to that of pH 4. INTRODUCTION The 2002 scientific journal‚ “The Costs and Benefits

Procedure: Part I: Titration with an Indicator 1. Fill the 50-milliliter buret with a 0.25 molar NaOH solution. 2. Record volume. 3. Measure out between 20 milliliters and 40 milliliters of the unknown HCl solution. 4. Record volume. 5. The amount of unknown HCl is then added to the 100-milliliter Erlenmeyer flask. 6. Add two drops of the indicator‚ phenolphthalein‚ to the acid in the flask. 7. Using the slider on the right hand side‚ add NaOH to the HCl in the Erlenmeyer flask (This action

analyzing pH it measures for the acidity or basicity of a solution. pH levels vary depending on the solution. The more acidic solutions would be juices and vinegar and cleaning materials would be basic. You can determine the purpose of solutions based on their acidity and basicity. We measure the pH of solutions on a scale with levels from 1-14. These levels may change if other solutions are added‚ we can tell what the pH will be based on its colour. Solutions called buffers change the pH levels of

The Effects of Change on People I admire the philosophy of King Whitney Jr.; he believes change has a considerable impact on the human mind. He quotes‚ “To the fearful it is threatening‚ it means that things may get worse. To the hopeful it is encouraging‚ it means things may get better and to the confident it is inspiring because the challenge exists to make things better‚” (Laura Moncur’s Quotes of the Da.y). How people react to change depends on their personality and the types of change that

Factors that affect how the PH changes during a titration experiment. Concentration of the alkali Having a higher concentration of alkali will mean that there will be more molecules closer together for the acid to collide with. This will speed up the reaction as collision theory suggests that molecules have to collide to react and if there are more molecules to collide with the reaction will happen faster as there is a higher chance of a collision. Volume of alkali An increase in volume would mean
