The antibiotic penicillin is isolated from <u><em>Penicillium notatum</em></u> fungi
Penicillin was first discovered in 1928 and was used at St. Mary's Hospital, London, by Alexander Fleming to heal wounds due to its antibacterial properties.
Explanation:
Fungi and bacteria usually produce antibiotics (as secondary metabolites) for defense mechanism. They do so to limit competition for resources with other neighboring fungi or bacteria in their environment. This is why when a fungus or bacteria establishes itself in an environment, you hardly see other fungi or bacteria types growing in their vicinity.

An insect bite on the face produces a break in the skin which introduces the normal skin flora (usually <em>Staphylococcus </em>and <em>Streptococcus</em>) to the sterile subcutaneous tissue causing inflammation. The inflammation of the subcutaneous tissue is called cellulitis. Since the infection is in the face, then it can travel from the infected site to the meninges through the cavernous sinuses and cause bacterial meningitis.
Skate park is a good example that maintains the law of conservation as skater neither creates nor destroys energy.
Explanation:
As per the law of energy conservation, energy cannot be created nor can be destroyed but it’s form can definitely be changed. This theory can be well justified by the example of skate park playground. According to the rules of this law a skater can never go high more than 2 meters on the ramp’s other side because it has that gravitational energy potential.
With every drop of the skater on the ramp the potential energy of the skater changes into kinetic energy. This two sides of the law justifies the fact that skate playground should be designed in such a way that it supports the law of conservation of energy.
