Two biological processes which control our stress response involve the hypothalamus and the autonomic nervous system. When a human is under threat‚ the sympathetic branch of the automatic nervous system becomes active and sends a signal to the adrenal medulla. Similarly‚ when the body is no longer under threat‚ the parasympathetic branch sends the body into a more relaxed state. Therefore‚ the human body will automatically react when the body is under threat or stressed and then help itself go back

constructed; there are also a lot of biological and genetic factors that contribute. Two biological factors that affect our gender roles are our genes and hormones. When a baby is first conceived it is genderless for the first seven weeks of development and‚ since there is no gender‚ the development for males and females during this period is identical. At seven weeks when the sperm and egg combine to form the zygote‚ the genes activate the babies’ biological sex. Everyone has 23 pairs of chromosomes

Three of the five major perspectives in Psychology are biological‚ cognitive and humanistic. The biological approach states that all behaviours‚ thoughts and feelings are caused by biological factors such as hormone production and genetics (McLeod 2007). For example the production of the hormone serotonin causes an individual to feel happiness‚ while genetics have evolved over the years so that human bodies and behaviour adapt to their environment‚ meaning that most behaviour we display today has

Biological vs Chemical Pest Control All living things strive to survive‚ but unfortunately the needs of other creatures sometimes conflict with our needs.
