Explanation:
The enterotoxins (also know as exotoxins when they are produced by bacteria) are polypeptides secreted by microorganisms that target the intestine. These toxins may produce serious damage to the host by disrupting the function of the epithelial intestinal cells Moreover, <em>Clostridium botulinum </em>is a Gram-positive bacterium that is able to produce a potent neurotoxin (botulinum) which is known to cause severe flaccid paralytic deformities in humans.
Since, the options have not been given, the question is incomplete. The complete question is as follows.
When Alexander Fleming discovered what was to become penicillin, he noticed that wherever mold was growing on plates of Staphylococus sp., there was a zone of inhibition of bacterial growth around the fungi. What type of symbiotic relationship does this describe?
A) Amensalistic
B) Cooperative
C) Mutualistic
Answer: A) Amensalistic
Explanation:
Amensalism is a symbiotic relationship between organisms that belong to different species, in this one organism is destroyed or inhibited in terms of growth and distribution but the other organism remains unaffected.
The given situation is the result of amensalism this is because of the fact that penicillin contains a fungal formulation which is likely to destroy the bacterial cells of Staphylococus sp. by creating a zone of inhibiting. Here, the fungal species will remain unaffected but the bacterial species will be inhibited.
One type of atom, such as hydrogen is called an element. An element is a pure substance, made up of only one type of atom. You can find the elements on the periodic table of elements, where they are listed.
