It was discovered by Alexander Fleming in the 1920's that Penicillium notatum produced a substance, know as penicillin, which ha
d antibiotic properties. Many would consider this to be one of the greatest and most important medical discoveries of all time. Penicillium notatum is what type of organism?
<em>Penicillium nonatum is a type of </em><em>bacterium</em><em>.</em>
<u>Bacteria are prokaryotic, microscopic organisms that are capable of adopting different lifestyles based on their mode of nutrition. While some are capable of manufacturing their foods via photosynthesis/chemosynthesis, some are saprophytic in nature while others lives as parasites on living organisms.</u>
Those that lives as parasites are often capable of causing diseases and are therefore called pathogens.
Penicillium nonatum is capable of producing a substance that has the capacity to inhibit the growth of another bacteria. Substances that are capable of inhibiting or killing bacteria are generally known as antibiotics.
Codominence is a condition in which two alleles of the same gene are expressed equally. Both alleles are capable of exerting their effects on the organism. Thus instead of expression of one trait both traits are expressed.
Natural selection is based on Darwin’s observation that individuals most likely to survive and reproduce are those with traits best suited to their current environment.
