Endocrine System Chapter 13 Study Guide Name ( ) Revision 2 OVERVIEW The endocrine system‚ like the nervous system‚ controls body activities to maintain a relatively constant internal environment. The methods used by these two systems are different. This chapter describes the difference between endocrine and exocrine glands‚ the location of the endocrine glands‚ and the hormones they secrete (objectives 1 and 6). It explains the nature of hormones‚ the substances that function as hormones

micronutrients. The term ‘vitamin’ was derived from ‘vitamine’‚ a combination word made up by a Polish scientist‚ Casimir Funk‚ from vital and amine meaning amine of life‚ because it was suggested in 1912 that the organic micronutrient food factors that prevent beriberi and perhaps other similar dietary-deficiency diseases might be chemical amines. This proved incorrect for the micronutrient class‚ and was shortened to vitamin. A vitamin is an organic compound required as a nutrient in tiny

New International Business Perspectives on Pakistan Omar J. Khan I Lyn S. Amine Executive Summary What image comes to mind when one thinks of Pakistan? Prior to the attacks of September 11‚ 2001‚ and the subsequent invasion of Afghanistan‚ many businesspeople had little information about this ancient land. Recently‚ Pakistan has come to the world’s attention as a powerful ally in the U.S.-led war against terrorism. Situated at the crossroads of the Middle East‚ Southeast Asia‚ China‚ and

accessory factors in addition to proteins‚ carbohydrates‚ fats‚ minerals and water. Then‚ in 1912‚ thee chemist Casimir Funk identified that the antiberiberi substance in unpolished rice was an amine (a type of Nitrogen-containing compound)‚ so Funk proposed that it be named vitamine‚ from vital amine. It was later discovered that different vitamins have different chemical properties. This discovery caused vitamine to be turned into vitamin. In 1912 Hopkins and Funk made a hypothesis

THE PROBLEM AND REVIEW OF RELATED LITERATURE AND STUDIES Introduction Everyone is naturally pre-determined to have an offspring. This would just exist in a relationship of a man and woman. It is not always true in a relationship if there is a new life that will be formed. Several factors may contribute to the hindrances in the formation of new life especially to man because male (sperm) gamete is the one responsible to initiate fertilization‚ the union of male (sperm) and female (ovum) gametes

Synthesis Procedure 1 -1.0 Introduction A Cobalt-Amine-Halide compound is synthesized from cobalt (II) chloride hexahydrate. An orange-tinted solid is produced and is considered to be unknown since the specific ligand amounts are unknown. By determining the percent composition of various elements and compounds in the unknown‚ its true identity can be predicted. Chloride‚ ammonia‚ and cobalt are three examples of percent compositions determined to help narrow the selection of possible unknowns
