Botulism can easily be prevented by boiling food prior to consumption.

<h3>What is Botulism?</h3>

Botulism may be defined as an imperative food poisoning that is provoked by botulinum toxin delivered in food by a bacterial species clostridium botulinum.

Clostridium botulinum inhibits the release of acetylcholine in the neuromuscular junction and causes defects in sensory perception through the central nervous system.

It can only be prevented by taking the proper boiled food prior to consumption.

The complete question is as follows:

  • boiling food prior to consumption.
  • administering antibiotics to patients.
  • not eating canned food.
  • filtering food.
  • preventing fecal contamination of food.

Therefore, the correct option for this question is A, i.e. boiling food prior to consumption.

A bee pollinates flowers social hierarchy social hierarchy territorial imperative territorial imperative competition competition
Ivanshal [37]

Answer:

cooperation

Explanation:

Cooperation occurs when living things of different species work together to benefit themselves. The interaction between a bee and a flower is a symbiotic relationship. A symbiotic relationship between two living things is one in which at least one of the parties benefits. The relationship between the bee and the flower is a mutual one because both parties benefit.

While the pollen and nectar serve as food for the bees, the spread of the pollen to other plants assist in the reproduction process.
