Astronauts completed an experiment where they cut up fruit inside the international space station and cut up fruit outside the space station in the vacuum of space with no oxygen. They noticed the fruit inside the space station had lots of enzyme activity while the fruit outside the space station had none.
What can they infer from this observation
Answers
Answer:
Astronauts basically do the same thing when they go to space. Preparation varies with the food type. Some foods can be eaten in their natural forms, such as brownies and fruit. Other foods require adding water, such as macaroni and cheese or spaghetti. Of course, an oven is provided in the space station to heat foods to the proper temperature. There are no refrigerators in space, so space food must be stored and prepared properly to avoid spoilage, especially on longer missions.
Condiments, such as ketchup, mustard and mayonnaise, are provided. Salt and pepper are available but only in a liquid form. This is because astronauts can't sprinkle salt and pepper on their food in space. The salt and pepper would simply float away. There is a danger they could clog air vents, contaminate equipment or get stuck in an astronaut's eyes, mouth or nose.
