When you are preparing or handling food, there are certain precautions to be followed to keep the eatables hygienic.
While handling food, one should remove before prepping food. He/she cannot wear rings, except the plain band. Bracelets and watches don’t matter as they are physically contaminated.
Eating, Drinking, Smoking, and Chewing Gum or Tobacco is strongly prohibited in the cooking area. Small droplets of saliva can contain thousands of pathogens, therefore, avoid spitting while prepping or serving food. Items of jewelry like rings, bracelets, and watches could collect soil and it could obstruct routine cleanup. As a result, the jewelry could act as a reservoir of unhealthful organisms which may transfer to the food.<span>

The hypothesis is an educated guess, so it cannot be used as a firm statement. In an experiment, the hypothesis is just a guideline that is tested & may or may not be true based on the results.
Hope that helps!

I would say individual biodiversity. I have read that there are variations in genes so genetic variation is a biodiversity along with species diversity and ecosystem biodiversity. In fact, genetic diversity is similar to species diversity. Species have their own genetic variation.

True. We are losing biodiversity at a higher rate than ever before.
The vegetation in most environments is crucial as a food source for many animals in the area. Without it, many animals may starve, thus setting on a chain reaction of animal displacement.
