1. What is the difference between Batesian and Mullerian mimicry?
2. Why do some deserts contain Entisols, rather than Aridisols?
3. How does eutrophication affect the properties of the water it occurs in?
1. Müllerian mimicry is when multiple species share the same warning coloration, but all of them have defenses and Batesian is when harmless species mimics aposematic coloration of harmful one
2.They are very dry
3. Eutrophication increased dissolved oxygen in the water
I mean, your second answer could be wayyyyyy more specific, but other than that, you're good.

This sounds like a stupid question but its valid. Why are deserts so dry?

Deserts are so dry because there is very little precipitation/humidity.

Wind traveling there cannot pick up moisture.

1. What is the difference between survivorship curves and the life table? Name and describe the three curves and three types of life tables.
2. Why are there different soil types in the cold deserts and the tundra, and what are their respective soil types?
3. Name 2 natural causes of NO[sub]x[/sub]/SO[sub]2[/sub] and 2 causes by humans.

Why would wind (do you mean the warm desert air?) not "be able" to pick up moisture? Shouldn't warm air have the capacity to hold more water then cold? Based on that fact alone, warm air should be able to accommodate a whole mess of water. Correct?

This website explains that in these cells, only dry air is descending on deserts, since cool air descends and is able to hold less moisture.

Thanks Kate. I do understand, having taught Earth Science for many years, but I was hoping to get student responses (rather than a link) on this beyond the "wind traveling there cannot pick up moisture" since they will be taking the State test next week Thanks again!
Thanks again!
