What can prevent a sand dune from moving?

Answers

Answer 1
Answer: Sand dunes move because of wind, so to prevent a sand dune from moving you need to either: stop the wind; or stop the sand dune from being able to move. For example, on beaches, sand is stopped from moving by using groynes, which physically stop the sand from being carried any further along the beach

Which food has been
refrigerated correctly?

Answers

Answer:

pls give more clues so that i can be able to answer your question.

Explanation:

Final answer:

To determine which food has been refrigerated correctly, consider the recommended temperature, proper packaging, and expiration dates.

Explanation:

To determine which food has been refrigerated correctly, we need to look at the temperature at which food should be stored. The Food and Drug Administration (FDA) recommends keeping the refrigerator temperature at or below 40°F (4°C). Foods that have been refrigerated correctly will maintain their freshness and quality. For example, raw meat and poultry should be stored in the coldest part of the refrigerator to prevent the growth of bacteria, while perishable foods like dairy products and leftovers should be kept at a consistent temperature.

Additionally, proper packaging is also important. Foods should be stored in airtight containers or wrapped tightly to prevent air and moisture from entering and spoiling them. This helps to maintain their taste and texture. Lastly, it is important to monitor the expiration dates of food items and discard any that have passed their expiration date.

In conclusion, a food that has been refrigerated correctly is one that is stored at the appropriate temperature, packaged properly, and has not exceeded its expiration date.
