Explanation:

A hypothesis is an idea or the assumption that is presented so that it can be examined or tested to check if its true or not. In any of the scientific process, the hypothesis is made before any proper experiment or research has been done, apart from basic knowledge.

Jada also made an assumption about the effectiveness of soap and sanitizers before any research.

Thus, the second statement is a hypothesis.

organisms that lack symmetry are called asymmetrical and belong to phylum porifera/sponges.

organisms with specialized stinging cells belong to phylum cnidaria. stinging cells are called cnidoblast cells.

cnidarians show two morphological forms : polyp (sessile) and medusa (mobile)
