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.

Answer:
Extrinsic regulatory mechanisms are external and depend on the firing of some factor outside the population itself. Among them are interspecific competition, food and space restrictions, very strong climatic variations, weathering and inharmonious relationships with other populations (parasitism and predatism).
Good examples of interspecific competition appear when rabbits, caves, rats compete for the same plant, or different fish and birds, such as the heron, vie for the same species of smaller fish. This is because these different species keep their populations in the same ecological niche. Competition is often so strong that some species eventually, as one example of an extrinsic homeostatic mechanism overriding an intrinsic homeostatic process is their disappearance or migration to other regions.
In this competition, the presence of adaptations among individuals in the population that promote better food search, speed, vision, and others can make the difference between elimination and survival.
The taxon that consists of one or more genera (plural form of genus) is the <u>family</u>.
Explanation:
According to the modern taxonomic classification system, there are eight major levels of division – Domain, Kingdom, Phyllum, Class, Order, Family, Genus, and Species.
Family is the taxonomic order which comes next to the Order and before Genus and consists of one or more genus or genera but sharing a common attributes. The ancestral origin of the family members remains the same.
The kinds of families depend upon the Kingdoms and Orders in the taxonomy. Carl Linnaeus termed family as familia in his classification and divided the major plant groups or families as trees, palms, ferns etc.
Among the family of carnivores in animals, there are many genera like Canidae, Felidae Ursidae etc.
Biotechnology use can lead to a decrease in pesticide and herbicide use, maintaining soil quality. Correct answer is A
The statement that best describes the result of the experiment is that students who spend less time studying after school get lower math grades. Option D
<h3>What is laboratory experiment?</h3>
The entire concept of an experiment is so that the empirical relationship between variables could be explored. Now we know that if not for experiment, we can not confidently say that A causes B. Thus, it is by the means of experiments that we can be able to establish the concept of causation.
Thus the statement that best describes the result of the experiment is that students who spend less time studying after school get lower math grades. Option D
