Natalka [10]

Answer:

Show that life can only come from life (rather than spontaneous generation)

Explanation:

Pasteur boiled a broth in a flask with an S-shaped neck. Thebend in the neck prevented particles from the air reaching the broth, but still allowed air to get in.  No bacteria grew in the flask.  

When the flask neck was broken so that particles could get inside, the broth became cloudy, showing that microorganisms were only able to grow from other living things from the outside, and not spontaneously from nothing

mariarad [96]

The correct option is (D) Many parasites release fertilized eggs in the feces of humans and other animals.

<h3>How toilets can prevent spread of disease?</h3>
  • Toilets save lives! Deathly infections proliferate quickly in an absence of restrooms. Every day, over 750 kids under five pass away from diarrhea brought on by contaminated water, subpar sanitation, and bad hygiene.
  • Girls who attend schools without restrooms may fall behind in their studies. Many students are compelled to skip school while they are on their period because there are inadequate sanitary facilities.
  • Toilets are an excellent purchase. According to data by the WHO, every dollar spent on cleanliness has a return of $5.50 USD.
  • However, 892 million individuals practice open defecation, which involves going outside and defecating in bushes, on the side of the road, or in garbage piles.
  • 90% of those who use open defecation live in rural areas, therefore it's frequently a question of where they are located.
