HORMONES Hormones are a class of regulatory biochemicals produced in all multicellular organisms by glands‚ and transported by the circulatory system to a distant target organ to coordinate its physiology and behavior. They serve as a major form of communication between different organs and tissues. Hormones regulate a variety of physiological and behavioral activities‚ including digestion‚ metabolism‚ respiration‚ tissue function‚ sensory perception‚ sleep‚excretion‚ lactation‚ stress‚ growth and

Hormones Every living organism on Earth has some sort of organ system. For example‚ humans have their endocrine system. The endocrine system is a group of organs that release different biological substances called hormones. There are vast amounts of hormones‚ which means there are multiple uses that are necessary for survival. Hormones have multiple roles in the human body. For example‚ they assure that growth‚ development and maturation occurs properly and on time. Also hormones‚ help control

Thyroid hormones are essential for the body to function normally. To achieve this purpose‚ the thyroid hormones must be present in the body in the correct amount -- not too little and not too much. Hyperthyroidism is the medical term applied to an over-active thyroid gland with consequent excess secretion of thyroid hormones (T3 and T4)‚ causing the body to “speed up.” Hyperthyroidism with an enlarged thyroid gland is more popularly known as toxic goiter. What are the causes of hyperthyroidism

TITLE : The copper cycle IN TRODUCTION The purpose of the experiment is to recognize that change of state‚ change in colour‚ formation of a precipitate‚ or the evolution of heat are associated with a chemical change; to study reactions of copper. Copper is an element that can be found in nature in a variety of different compounds. The most common natural ore is the sulphide‚ known as chalcocite‚ Cu2S. This mineral is an important source of copper metal because it is about 80% copper by

Purpose: During this experiment‚ we were trying to see whether copper‚ after a chain of chemical reactions‚ will revert back to its elemental form. Procedure: First‚ I added nitric acid with copper in a beaker‚ which turned into a copper nitrate‚ a blue-green solution. Afterwards‚ I added sodium hydroxide‚ and my solution colored to a dark blue solution called copper hydroxide. I heated the solution to evaporate the water and I got a brownish-blackish solid called copper oxide. Once the

Introduction: Plant hormones and growth regulators are chemicals that affect flowering‚ aging‚ root growth‚ killing of leaves‚ promotion of stem elongation‚ color enhancement of fruit‚ prevention of leafing‚ and many other conditions. Very small concentrations of these substances produce major growth changes. All plants produce hormones naturally‚ and growth regulators can be applied by people to are applied to plants by people. Plant growth regulators may be synthetic compounds that mimic naturally
