1. Two advantages of having a coelom: (a) better body movement of the organism, (b) helps in proper circulation of nutrients, body fluids, and gases. It also helps in excretion.
2. Protostome: protostome is the primitive invertebrate who undergo through protostome during the embryonic development. In the case of protosome the blastophore has been developed into a mouth. Deuterostome: Deuterostome is being considered as the sister clade of the protostomes. For the deuterostomic embryotic development, the deuterostomes are being distinguished from the protostomes. The blastophore has been developed into the anal opening. Starfish and sea urchins are the two examples of the deuterostome.
3. Cephalization includes the evolutionary attitude of moving the nerves and sense organs towards an anterior organ to create the head like structure (Niven & Chittka, 2016). This mollusk shows this cephalization. By observing the structure of mollusc a tiny head like structure can be seen. The anterior end can be seen prominently this proves the cephalization among the mollusc.
4. In the case of the locomotion, squids use cephalopods. These cephalopods are commonly known as the head feet. By using this squids generally move. To acquire the food, the squids normally depend upon the open water food web. With their long tentacles they generally grab food and eat it. In the case of calms, they generally involve in the bivalve locomotion. In general the clams use their feet for the lateral movement. The clams are the filter feeder. They eat microscopic plankton through their gild. In the path of their movement they sieve all the microscopic plankton and eat them to compensate the nutrient.
5. The earthworms are classified into the phylum of the Annelida (Zwarycz, Nossa, Putnam & Ryan, 2016). All the body segments of the earthworm are joined with small ring-like things. Around 100 to 150 segments are available in the body of...
