Which is the class of cnidarian that is characterized by having a dominant medusa stage and four gastric pouches?

scyphozoa

Explanation:cniderians are aquatic animals.they have radial symmetry, that is they can be divided into two halves through any plane.

Cniderians may have nematocyst,which are stinging cells.

They have two forms,which are polyp and Medusa .

There are four classes of cniderians;hydrozoa, scyphozoa,cubozoa and anthozoa.

Scyphozoa are predominantly medusa,which is umbrella shaped.they are jelly fishes.

They have four or eight oral arms.

They possess four gonads and four gastric pouches .an example is the Aurelia.

the binding of the substrate is dictated by the shape of each molecule. side chains on the enzyme interact with the substrate in a specific way, resulting in the making and breaking of bonds.

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )
