Answer:

Planarian is a member of the family Planariidae and is one of the flatworms present on the planet.

These planarian species have bilateral symmetry with a soft, leaf-shaped and ciliated body of 3 to 15 mm length and can grow up to 30 cm.

Its head is spade-shaped with two eyes which help him in running away from light and a brain made of ganglion cells. The mouth is present on the ventral (lower) side of the body towards the tail which is pointed.

Head and tail region of planaria show the difference as the head part contains eye-spots and is broad whereas tail part contains mouth near to it and is pointed.

Answer:

C.) crystalline solids

Explanation:

The solid materials may be crystalline or amorphous. The concept of crystal structure is related to the organization of atoms in a geometrical form. Crystalline structures are present in various materials, where atoms distributed within their structure form a network called the crystalline lattice. Therefore, crystalline structures have salts, metals and most minerals. Crystalline structures are formed by unit cells that are their basic unit, as they constitute the smallest set of associated atoms found in a crystalline structure.

The molecules of the crystalline structures can have two types of bonds, the directional ones, which include the covalent and dipole dipole and the non-directional ones where the metallic, ionic, van der Walls bonds. When formed by ionic compounds, these crystalline structures can result in crystalline solids.
