Wind is related to the movement of warm and cold air masses. which kind of heat transfer does this represent?
a. radiation
b. conduction
c. convection
d. absorption

When wind is related to the movement of warm and cold air masses the type of heat transfer that this represents is convection.

Explanation:

Convection is that the circular motion that happens once hotter air or liquid that has quicker moving molecules, creating it less dense rises, whereas the cooler air or liquid drops down. Convection may be a major factor in weather.

answer; i believe is(b)converging

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.
