and magazine articles have suggested that humans may be at risk because small amounts of well known environmental contaminants‚ such as dioxin‚ PCBs and DDT‚ can affect hormone levels. Hormones are produced by the endocrine system as regulators of biological function in target organs. Because hormones play a critical role in early development‚ toxicological effects on the endocrine system often have an impact on the reproductive system. The term endocrine disruptor is used to describe chemicals that

Introduction Sociobiologists believe human behavior has developed through evolution in the same manner that physical characteristics have. They describes how psycho-sexual gender differences have evolved by using a Sociobiological method of explanation. They say that these gender differences are based on two indisputable biological facts. First‚ humans as biological beings have a propensity for maximizing their reproductive success in order to ensure that their genes will be passed on and they will

Endocrine system or endocrine disruptor is not something we commonly hear or discuss about in our society. However‚ they both play a big role in humans. Many people have no insight of endocrine system or endocrine disruptor. The endocrine system is glands secreting different types of hormones that go directly into bloodstream to transfer information and instruction to one set of cells to another certain cells. Hormones are the body’s chemical messenger which regulates growth and development‚ body’s

Chapter 3 The Biological Bases of Behavior Communication in the Nervous System * Nervous Tissue: The Basic Hardware * Neurons are individual cells in the nervous system that receive‚ integrate‚ and transmit information. * The soma‚ or cell body‚ contains the cell nucleus and much of the chemical machinery common to most cells. * Dendrites are the parts of a neuron that are specialized to receive information. * The axon is a long‚ thin fiber that transmits signals

disorder can be attributed to many biological‚ psychological and social variables that work in tandem to produce healthy or unhealthy behavior” (Kearney & Trull‚ 2015‚ p. 47). The problem with this model is that it does not take into account that each human person has a free will gifted to them from God. Free will allows human beings to be the authors of their own actions instead of believing that external conditions control them. A Christian model of behavior stems from a holistic approach in

The importance of water in Biological Systems Much of the Earths surface is comprised of water‚ as well as much of biological systems; for instance‚ the human body consists of approximately 70% of water‚ and in other biological organisms this figure could even be 95%. This largely relies on the bonding of water‚ whereby two hydrogen atoms bond to one oxygen atom; hydrogen bonding is the strongest intermolecular force due to its high polarity. Hence‚ what is the biological importance of water? Water
