1. if you exercise on a hot day, you need to worry about dehydration. in this context, what do you think dehydration means?
2. astronauts and backpackers often bring dehydrated food. what do you think dehydrated food is?

Explanation:

1. Dehydration occurs when the body loses more water than it takes in, often due to sweating during exercise in hot conditions. This can lead to a lack of proper bodily - fluid balance.
2. Dehydrated food is food from which most of the water content has been removed. This process helps in preservation and makes the food lighter and easier to carry for astronauts and backpackers.

Answer:

1. Dehydration means the body losing a significant amount of water, often through sweating during physical activity in hot weather, leading to an imbalance in bodily fluids.
2. Dehydrated food is food with most of its water content removed, making it lighter and more shelf - stable for long - term storage and transport.
