Answer:
Mollusca Phylum
Gastropoda class
Explanation:
The Mollusca Phylum is one of the most noticeable phyla that includes a wide variety of forms.
The ancestral Mollusca used to habit the pre-cambric oceans. It was bilaterally symmetrical, with a well-defined head that had tentacles and ocellus. Its ventral surface was plane and muscular, shaping a reptant foot. The dorsal surface was protected with a convex and oval shell.
The Gastropoda class is the richest class among all mollusks. This class experienced a characteristic torsion in their shell. This twist also involved the visceral mass, the mantle, and the mantle cavity. But by the time that this torsion occurred, the shell had already experienced a turn into a coil shape, which was then followed by its torsion.
The typical gasteropod´s shell is a conical structure composed of several tubular spirals containing the individual´s visceral mass. The biggest spiral ends as an opening from which the head and the food protrude.
When the effects of genes add up to make the phenotype, they are called additive genes.
When a client comes into the emergency room (er) after hitting his head while playing any sport, if he is alert and oriented. immobilize the client´s head and neck would be a priority nursing intervention, because a head injury is treated as if a cervical spine injury is present until x-rays confirm their absence, then call for an immediate head computed tomography to look for any spine or head injury.
