They both are home to different types of cacti.
They both are home to different types of cacti.

They both have temperatures that reach 120°F.

Answer 1

Deserts and tundras have some similarities, but let's clarify the provided statements:

1. They both have a top layer of permafrost. - This is not accurate. Only tundras typically have permafrost. Deserts do not.

2. They both receive up to 25 cm of precipitation each year. - This statement is generally true. Both deserts and tundras are characterized by low precipitation levels, often less than 25 cm annually.

3. They both are home to different types of cacti. - This is incorrect as well. Cacti are primarily found in desert environments and are not native to tundras.

4. They both have temperatures that reach 120°F. - While deserts can reach high temperatures like 120°F (about 49°C), tundras do not reach such extreme temperatures.

The correct similarity is the low precipitation, making the second statement the most accurate.
