Biology – Pattern in Nature 1. Organisms are made of cells that have similar structural characteristics 1.2.1 Outline the Historical development of the cell theory‚ in particular‚ the contributions of Robert Hooke and Robert Brown. • 1665 English scientist Robert Hooke used microscope to examine thin slices of cork and saw small box-like compartments he called cells. He was first to realise plant material had organised structure at microscopic level. (compound microscope) • 1831 Scottish Botanist

research task 1. Explain the difference between a prominence and a solar flare? Prominence are huge loops of gas that connect different parts of sunspot regions. A solar flare is an explosion caused by hydrogen getting really hot‚ the gas shoots out into space causing a solar flare. 2. Use a diagram that describes what causes the aurora? 3. Diagram that demonstrats the annular eclipse? 4.Is 2500 a leap year? NO 5. Compare the geocentric and the heliocentric models? Geocentric - model

Franscesco Redi used a microscope to observe that flies do not spontaneously appear but develop from eggs laid by other flies. Many years later‚ Robert Brown observed a large body in

Examine the nature‚ spatial patterns and future directions of one economic activity in a global context The global wine industry involves two distinct activities‚ viticulture and winemaking. Viticulture is the cultivation and harvesting of grapes and winemaking is the production of an alcoholic beverage via the crushing and fermentation of grapes. The spatial distribution of winemaking is now known as to be either old world or new world and the characteristics of these different areas determine

Temperature range Background: All organisms are adapted to a particular environment with its characteristic temperature range. The temperature range allows the organism’s enzymes to control its metabolism by operating at their optimum efficiency within this range. Some organisms are adapted to live at high temperatures (80 - 100oC) and these are called thermophiles

Biology 1010 is a course that introduces students to the basic biological phenomena in all living organisms. It focuses on the different molecular levels of organization‚ heredity in evolution‚ genetics and reproduction. Through this course‚ I was able to master three essential concepts such as Mendel’s Law of Segregation‚ enzymes‚ and photosynthesis. Gregor Mendel was an Augustinian monk that argued that parental traits are passed on to their offspring discrete “heritable factors”. Heritable factors
