Coastal waters have about 26% of all biological diversity. This world of seabirds, clams, crabs, starfish, anemones, fish, kelp, and marine mammals, among many others, is a beautiful place with many different types of plants and animal communities.
Answer:
The variation might occur in the population that leads to the evolution of the species. This variation may occur due to natural selection, mutation or recombination.
The variation might change the genotype and allelic frequency of the population and might also change the phenotype of the individual in the population. The breeding adults of the left mouthed in 1981, 1987 and 1990 shows variation and was equally opposite phenotype which is more common in the population.
The false statement is: Growth hormone is produced by the posterior pituitary
Growth hormone (GH) or somatotropin is produced in the cells called somatotrophs of the anterior pituitary gland. GH is a peptide hormone that stimulates growth, cell reproduction, and cell regeneration. Its function is involved in metabolic processes (favors anabolism or synthesis of macromolecules). Also, growth hormone stimulates production of IGF-1 and increases the levels of glucose and free fatty acids.
