Question

Which statement is true about a species living in a homogenous environment compared to a species living in a heterogeneous environment? A species that lives in a homogeneous environment is more likely to exhibit phenotypic plasticity. The homogeneity or heterogeneity of an environment does not determine whether a species will exhibit phenotypic plasticity. Only a large population in a homogeneous habitat can exhibit phenotypic plasticity. A species that lives in a heterogeneous environment is more likely to exhibit phenotypic plasticity.

Answer 1

Answer:

A species that lives in a heterogeneous environment is more likely to exhibit phenotypic plasticity.

Explanation:

Phenotypic plasticity might be understood as the ability of a genotype to produce different phenotypes in response to varying environmental conditions.

Phenotypic plasticity needs epigenetic mechanisms to occur, which involve the genotype and the environment interaction to produce adapted phenotypic changes.

Epigenetic mechanisms produce changes in the expression of the genes, with no need to alter the DNI nucleotides sequences.

A heterogeneous environment imposes variability on genotypes that interact with it, producing different phenotypes. These phenotypes will vary according to environmental conditions.
