Which characteristic of a population would most affect its survival one threatened by global climate changes A. Biochemical adaptation B. Genetic specialization C. Genetic diversity

B. Genetic specialization

Explanation:

The characteristic of a population that would most affect the survival of a species, threatened by global climate change is genetic specialization.

Genetic specialization is the term that refers to the forced adaptation that a species has to undergo in order to survive in a given environment. in the case of a region with constant global changes, genetically specialized species may find it difficult to find the food necessary for their survival, and even fail to establish effective reproduction. Thus, the birth rate within this species will be much lower than the mortality rate, and may threaten the survival of the species.

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.
