You place a potato slice in a sucrose solution of unknown concentration, and leave it there for 2 hrs. When you return and weigh the potato slice, you find that the weight of the potato slice has increased. You conclude that the sucrose solution isto the potato cells. [2 pt]

You conclude that the sucrose solution is hypotonic to the potato cells.

Explanation:

A solution is said to be hypotonic with respect to other solution if its concentration is less than the other solution to which it is compared.

A  concentration of solvent molecule in a hypotonic solution is higher than hypertonic solution so solvent moves from hypotonic to hypertonic solution due to osmosis.

The increase in weight of potato shows that it has gained water i.e. the water has entered from the sucrose solution to cells. So, the sucrose solution is hypotonic to the cell sap.

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)

filter feeding is observed in porifera members.  

alternation of generation is observed in coelenterata or cnidaria. there is alternation of asexual polyp form and sexual medusoid form. it is also referred as metagenesis.

after receiving a stimus, the sensory receptors send(s) signals to the appropriate area of the body.  

the must be sensory neurons.
