Answer 2

Answer:

1. The mouth parts are of siphoning type and are comprised of a basal transverse and rectangular labrum, a pair of reduced mandibles, a pair of maxillae (galeae) forming a long and coiled proboscis and paired labial and maxillary palps. The proboscis is hollow internally and remains coiled under head when not in use.
2. The mouth parts of honey bee are attached to the lower part of the head and are of chewing and lapping type. These are modified for collecting the nectar and the pollen. Mouth parts consist of labrum, epipharynx, mandibles, maxillae and labium.
3. A bipinnaria is the first stage in the larval development of most starfish, and is usually followed by a brachiolaria stage. Movement and feeding is accomplished by the bands of cilia. Starfish that brood their young generally lack a bipinnaria stage, with the eggs developing directly into miniature adults.
4. echinopluteus larva. A planktonic and feeding larval form that possesses limb-like outgrowths bearing ciliated bands.
