Toby is a 16 year-old, pimple-faced boy, who has been working after school at a local pizzeria trying to make a little money for his new guitar. 2 days ago, Toby was working in the kitchen, shredding pounds and pounds of cheese for pizza. The cheese was used to prepare pizzas for many customers.
Today, the pizzeria got many phone calls with complaints from customers experiencing nausea, vomiting, and diarrhea, blaming their symptoms on the pizza they ate yesterday.

Explain, what could have happened here. Which bacteria do you think, caused these symptoms, how, and why?

You described Toby as a pimple faced boy, so I think something might have happened with his acne. He might have touched/burst one of them and got the bacteria on the cheese. The bacteria colonizing the pore could have been cutibacterium acnes. They are there to generate enzymes to degrade skin, which may have made the customers sick when they ingested it. There's still lots of research going into the bacteria behind face oils and pimples, but this is the best answer i can give with this information!

Science27 of the most iconic, jaw-dropping photos of the earth and the moon from spacedave mosher  oct 1, 2018, 11: 13 am etnasa/flickrapollo 11 astronauts took this photo of earth on july 20, 1969.from the ground, earth looks like a boundless fertile plain that beckons to be explored and exploited.but astronauts would beg -  and even plead  - to differ."you realize that people often say, 'i hope to go to heaven when i die,'" jim lovell, an astronaut who flew on the apollo 8 and apollo 13 missions to the moon, previously  told business insider. "in reality, if you think about it, you go to heaven when you're born."lovell has seen first-hand that we live on a tiny rock hopelessly lost in the void. he's also quick to tell you it's the only one we've got - a  fragile spaceship  for more than 7 billion people: "you arrive on a planet that has the proper mass, has the gravity to contain water and an atmosphere, which are the very essentials for life. and you arrive on this planet that's orbiting a star just at the right distance - not too far to be too cold, or too close to be too hot - and just at the right distance to absorb that star's energy and then, with that energy, cause life to evolve here in the first place. in reality, you know, god has really given us a stage, just looking at where we were around the moon, a stage on which we perform. and how that play turns out is up to us, i guess."humanity has recorded photos of earth from hundreds, thousands, millions, and even billions of miles away, some of them taken by lovell himself.these images not only scientists study our dynamic world, but also understand how a habitable planet looks from afar, which aids the search for  more worlds. most importantly, however, the images underscore our peculiar existence on  a mote of cosmic dust.take a moment to ponder 27 of the most arresting images of earth that humankind has ever captured from space.a
