complex pathways of veins‚ arteries‚ and capillaries. The heart‚ blood vessels‚ and blood help to transport vital nutrients throughout the body as well as remove metabolic waste. They also help to protect the body and regulate body temperature. Bacterial endocarditis is an infection of the inner surface of the heart or the heart valves caused by bacteria usually found in the mouth‚ intestinal tract or urinary tract. This infection results in a serious illness which requires prolonged treatment and

as spinal meningitis. Meningitis is usually caused by a viral or bacterial infection. Knowing whether meningitis is caused by a virus or bacterium is important because the severity of illness and the treatment are different. Viral meningitis is generally less severe and resolves without specific treatment‚ while bacterial meningitis can be quite severe and may result in brain damage‚ hearing loss‚ or learning disability. For bacterial meningitis‚ it is also important to know which type of bacteria

simple have complex systems that they use to communicate with each other to coordinate. This is crucial to humans because Dr. Bassler considers humans to be 90-99% bacterial. Dr. Bassler states we have about one trillion human cells but we have about 10 trillion bacterial cells that either live in or on humans. The number of bacterial genes in those cells outnumber humans by 100 times since humans only have 30‚000 genes. These bacteria share a mutualistic relationship with the humans. For example

In this lab‚ we tested the effects of temperature on fungal amylase and bacterial amylase (Aspergillus oryzae and Bascillus Licheniformis). We used 4 different temperatures in Celsius 0‚ 23‚ 58‚ and 89 for both fungal and amylase. For 10 minutes‚ every 2 minutes we would use 3 drops of each amylase and mix it with iodine to observe the presence of starch at each temperature. We conducted this experiment for both bacterial and fungal amylase. Results were reached based on the color of the iodine
