Question

Quizplus · Accepted Answer

Epigenetic molecules include DNA methylation and histone modification, which can be influenced by environmental factors and lead to changes in gene expression. Neurogenesis (A) refers to the production of new neurons and is not directly related to altered gene expression. Lateralization (B) refers to the specialization of brain regions for different functions, which is largely determined by genetics rather than environmental factors. Natural selection (D) refers to the process by which certain traits become more prevalent in a population due to better survival and reproduction, and is not directly related to altered gene expression.
