Answer:

e. staphylococcal enterotoxin

Explanation:

Staphylococcal enterotoxin is a toxin that is produced by the bacteria Staphylococcus aureus. It is a toxin found inside the gastrointestinal tracts of the human body which is why it is called an enterotoxin and it results in food poisoning when consumed by humans.

Staphylococcal enterotoxin is proteinous in nature and it can be found on dairy products such as milk or cheeses that have been contaminated by Staphylococcus aureus.

After consumption of the contaminated milk or cheeses, the person begins to experience symptoms of nausea, diarrhea as well as vomiting.

Staphylococcal enterotoxin is a very heat stable toxin which means even though you heat up a food contaminated with this toxin, the bacteria may die by the toxins would still remain in the food.

The best way to avoid food poisoning by Staphylococcal enterotoxin is to avoid eating contaminated foods.

Choose the correct statements 1.Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same f
Mamont248 [21]

Answer: The correct statements are 1 and 2:

1.Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant.

2.Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.

Explanation:

Pollination is the transfer of pollen grains from an anthers to a receptive stigma. In most species of flowering plants, external agents bring about pollination. Also, flowers have evolved special structures and mechanisms to ensure successful pollination.

There are two types of pollination

--> Self pollination: This takes place when mature pollen grains from the anther of a flower fall on the stigma of the same flower or that of another flower on the same plant. This type of pollination brings the male gametes and egg cells of the same plant together. The resultant offspring show very little genetic variation.

--> Cross pollination: This occurs when mature pollen grains of a flower are transferred to the stigma of a flower of another plant of the same or closely related species. This brings the male gametes and egg cells of two different parent plants together. Therefore, there is greater genetic variation among the offspring.
