The United States Marine Corps (USMC) is a branch of the United States Armed Forces responsible for providing power projection from the sea, using the mobility of the United States Navy to rapidly deliver combined-arms task forces. It is one of seven uniformed services of the United States. Created in 1775, the Marine Corps has been a component of the United States Department of the Navy since 1834, often working closely with naval forces for training, transportation, and logistics.
Captain Samuel Nicholas formed two battalions of Continental Marines on 10 November 1775, in Philadelphia as naval infantry. Since then, the mission of the Marine Corps has evolved with changing military doctrine and American foreign policy. The Marine Corps has served in every American armed conflict and attained prominence in the 20th century when its theories and practices of amphibious warfare proved prescient and ultimately formed the cornerstone of the Pacific campaign of World War II. By the mid-20th century, the Marine Corps had become a major theorist and practitioner of amphibious warfare. Its ability to rapidly respond on short notice to expeditionary crises gives it a strong role in the implementation and execution of American foreign policy.
Military organisation is the structuring of the armed forces of a state so as to offer military capability required by the national defence policy. In some countries paramilitary forces are included in a nation's armed forces. Armed forces that are not a part of military or paramilitary organisations, such as insurgent forces, often mimic military organizations, or use ad hoc structures.
Military organisation is hierarchical. The use of formalised ranks in a hierarchical structure came into widespread use with the Roman Army. In modern times, executive control, management and administration of military organisations is typically undertaken by the government through a government department within the structure of public administration, often known as a Department of Defense, Department of War, or Ministry of Defence. These in turn manage Armed Services that themselves command combat, combat support and service support formations and units.
The United States Marine Corps Women's Reserve served in two World Wars before becoming a part of the regular United States Marine Corps.
Science of drugs including their origin, composition, pharmacokinetics,
pharmacodynamics, therapeutic use, and toxicology.
Pharmacology (from Greek φάρμακον, pharmakon, "poison" in classic Greek; "drug" in modern Greek; and -λογία, -logia "study of", "knowledge of") is the branch of medicine and biology concerned with the study of drug action, where a drug can be broadly defined as any man-made, natural, or endogenous (within the body) molecule which exerts a biochemical and/or physiological effect on the cell, tissue, organ, or organism. More specifically, it is the study of the interactions that occur between a living organism and chemicals that affect normal or abnormal biochemical function. If substances have medicinal properties, they are considered pharmaceuticals.

Finance is the practice]citation needed[ of funds management, or the allocation of assets and liabilities over time under conditions of certainty and uncertainty. A key point in finance is the time value of money, which states that a unit of currency today is worth more than the same unit of currency tomorrow. Finance aims to price assets based on their risk level, and expected rate of return. Finance can be broken into three different sub categories: public finance, corporate finance and personal finance.
