Answer 1

Answer:

a. Identify the species of algae from samples of ocean water.

the others need a microscope i think.

Answer 2

Your answer is option (c). In my opinion the other options are not suitable for a common man at Beach. For that some lab tools are required but for salinity test you just need to do evaporation or also you can use a common pH paper to find.
