Introduction Environmental Engineering is a discipline of engineering devoted to the development and application of scientific knowledge through technology to eliminate or minimize adverse effects associated with human activities. It operates at four different levels: remediation of contaminated sites‚ treatment of effluents‚ pollution prevention‚ and care for future generations. Environmental engineering is fundamentally object-focused‚ rather than tool-based. It therefore draws from

Genetic influences and environmental influences have the potential to positively or negatively affect the fetus. Genetic influences are inherited and environmental influences pertain to the environment and these are not inherited. For the purpose of this discussion‚ an explanation of how these influences negatively affect the development of a fetus will be rendered. In defining and describing the genetic influences‚ Dominant-Recessive Inheritance transpire when a single allele disturbs the
