I'm having some trouble on these questions and I was wondering if I could have some help/be pointed in the right direction.

Question

1. Which of the following about Protists is FALSE?
a) They are prokaryotes
b) The animal-like protists are the protozoans
c) The photosynthetic protists are the algae
d) Many protists can cause human diseases

&:

2. The protists diatoms:
a) Are unicellular photosynthetic organisms classified as golden algae
b) Are an important past of phytoplankton, providing food for ocean-dwelling animals
c) Die and leave behind delicate silica shells, mined from ocean deposits because it is useful in tooth and metal polishes
d) All of the above.

I'm lost on the first one but I think the answer to the second one is D.

Help?

Since this is not my area of expertise, I searched Google under the key words "protists diatoms" 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.

I hope this helps. Thanks for asking.
