Answer:
Diffusive force J = 9590
Explanation:
From the given information:
Concentration gradient C₁ - C₂ = 35 mM = 35 × 10⁻³ M
membrane width Δ x = 1 cm = 10⁻² m
Solubility S = 1
diffusive area A = 10
Temperature T = 1° C = (273 + 1 )K = 274 K
Using the expression:
Diffusive force J = 9590
A observation and hypothesis
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.
