system‚ supporters of using animals as test subjects argue that although useful running test on single cell organism is not as accurate (Pro 2). Testing on single cell organisms would not show the potential effects on the central nervous system‚ endocrine system‚ or immune system -- all of which could cause severe damage or death to those who consume the drug (“Pro 2”). In contrast opponents argue‚ that it is better than using voluntary human test subjects to use to see the potential effects of drugs

BASIC CONCEPTS ENDOCRINE SYSTEM :- In physiology‚ the endocrine system is a system of glands‚ each of which secretes a type of hormone into the bloodstream to regulate the body. It derives from the Greek words endo meaning inside‚ within‚ and crinis for secrete. The endocrine system is an information signal system like the nervous system. Hormones are substances (chemical mediators) released from endocrine tissue into the bloodstream that attach to target tissue and allow communication among

Nerve and neuron sound similar to most people‚ but they are two different components of the body (Martini‚ 375). Nerves are found only in the peripheral nervous system‚ while neurons are found in the brain‚ spinal cord‚ and peripheral nerve (Martini‚ 375). Neurons are nerves cells that are specialized for intercellular communication (Martini‚ 375). A neuron is composed of a cell body‚ dendrites and axon (Marieb‚ 376). A nerve is a bundle of axons or dendrites that is wrapped in connective tissues

views are how one adapts‚ and the evolution of their behavior. Sociocultural views are how ones social interaction and culture effects one behavior. B.F Skinner and his study an on behavior is interesting especially when he did the Skinner box with the rat to see the behavior or positive and negative rewards. It shows how one can learn and chance a behavior if positively or negatively affected. Part II: Research Methods Describe research methods used in psychology by completing the following table

Margaret A. Hamburg‚ a FDA Commissioner who is credited with a master’s degree once said‚ “A safe global food supply can only be achieved through development of effective food safety management systems‚ which are essential to the well being of consumers‚ farmers‚ processors and manufacturers.” Food is a fundamental desideratum for survival‚ and the safety of food has been a controversial issue elevating up in America. The Food and Drug Administration (FDA) is the organization which governs food in

biological psychology is that human behavior is the result of internal physical‚ chemical‚ and biological processes. Biopsychology aims to uncover explanations for behavior through brain activity‚ the nervous system‚ physical factors‚ genetic makeup‚ the endocrine system‚ bio-chemistry‚ and evolution (Robins‚ Gosling & Craik‚ 1999). Historical Beginnings Historically‚ biopsychology can be dated back to the Ancient Greeks. Plato was the first to propose that the brain was the organ of reasoning unlike

It protects crops from insect pest‚ weeds and fungal diseases while they are growing‚ it prevents rats‚ mice and other insects from contaminating foods whilst being stored and finally‚ safeguard human health‚ it stops crops from being contaminated by fungi‚ this obviously affects us because then we are the ones who eat the crops.
