BPA is a weak agonist to estrogen receptor β, but compared to estradiol, its activity is 1000-fold less
Explanation:
Answer:
Option A, all of the genes found within the ecosystem
Explanation:
Genetic diversity is very essential to maintain the health of the population of any species. It includes all forms of alleles with in a specific species to ensure variability. Variability is essential to allow evolution of species through mating where species with more desirable genes mate to produce healthy offspring. Sub groups with in a species can also varying set of genes thereby making a gene pool.
Hence, option A is correct
