The group includes bacteria‚ fungi (yeast and molds)‚ protozoa and microscopic algae. It also includes viruses‚ those noncellular entities sometimes regarded as straddling the border between life and nonlife. People tend to related these microbes only with major disease such as AIDS‚ uncomfortable infections‚ or such common inconveniences as spoiled

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.

If a multiple colored film petri dishes are place under a 50 watt lamp‚ then the rate of photosynthesis will be greater for those with red‚ blue and clear film‚ than those with green and black film. We believed the petri dishes with the red‚ blue and clear film would produce the best results of photosynthesis as compared to the petri dish with the green and black film. This is said because chlorophyll absorbs red and blue wavelengths
