what enzyme do bacteria se to break down starches?

List the three protozoan kingdoms. Which of thse kingdomsdo the slime molds belong to?

what is the unique mode of reproduction that is characteristic of the scyphozoans?

Since this is not my area of expertise, I searched Google under the key words "protozoan kingdoms" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.

I hope this helps. Thanks for asking.
