c. Social Sciences

Explanation:

Linguistics can broadly be defined as the scientific study of language and its structures. It includes the various analyzing of the language form, context, phonetics and semantics among others. As a category of social science, it involves the relationships between individuals and their languages they use. Among one of the major branch of social science, it deals with the cognitive and the social aspects of people or individuals.  

in 1972 the fluid—mosaic membrane model of membrane structure was proposed based on thermodynamic principals of organization of membrane lipids and proteins and available evidence of asymmetry and lateral mobility within the membrane matrix [s. j. singer and g. l. nicolson, science 175 (1972) 720–731].

organisms that lack symmetry are called asymmetrical and belong to phylum porifera/sponges.

organisms with specialized stinging cells belong to phylum cnidaria. stinging cells are called cnidoblast cells.

cnidarians show two morphological forms : polyp (sessile) and medusa (mobile)

filter feeding is observed in porifera members.  

alternation of generation is observed in coelenterata or cnidaria. there is alternation of asexual polyp form and sexual medusoid form. it is also referred as metagenesis.
