change in the earth and what it does to the concentration in the oceans water. When global changes occur‚ they don’t only change that one thing it changes many things. Such as concentration in the water. For example‚ when heavy machinery or facilities burn fossil fuels‚ which releases more carbon dioxide in the air‚ the ocean sucks it up and the acidity in the water completely changes even if it goes up by .1 or .2 percent it’s still a lot and will affect all the life in the water. Our guiding question

MICROBIOLOGY COURSEWORK The effect of antibiotic concentration on bacterial growth Introduction Null Hypothesis- Increasing the antibiotic concentration has no effect on bacterial growth. Experimental Hypothesis- Increasing the antibiotic concentration decreases bacterial growth. Scientific Theory Bacteria are prokaryotes and can be identified by their shape. Spherical bacteria are called cocci‚ rod shaped bacteria are called bacilli‚ spiral shaped bacteria are called spirilla and

Investigating How Concentration of Acid Affects the Reaction Between Calcium Carbonate and Hydrochloric Acid Introduction ============ According to the collision theory temperature‚ concentration‚ surface area and catalysts all affect rates of reaction as shown in the diagrams below. Increasing any of these should increase the number of collisions and so increase the reaction rate up to an optimum point. Increasing the temperature causes the particles to collide with more

different pH solutions as well as to measure the absorbance of catecholase in solutions with different concentrations of potato juice and phosphate buffers. Absorbance of the enzyme catecholase was at an optimum level when pH was close to neutral. When pH was acidic or basic‚ the catecholase was less effective. Also‚ when there was a higher concentration of potato juice and a lower concentration of phosphate buffer‚ absorbance of the enzyme increased. Introduction According to Edmund J. Stellwag

The effect of nutrient concentration on duckweed growth Gina Neonakis Biology 203L:11 Biology 203:10 November 14‚ 2011 Abstract Lemna minor‚ or duckweed‚ is a small plant that floats on the surface of stagnant water that is usually rich in nutrients. Phosphorus is an important macronutrient in the growth of aquatic plants. We tested the effect of phosphorus on duckweed population growth using a control medium rich in nutrients and compared it to the population growth in a medium that lacked
