Biology: Cell Biology Basics

Molecular Biology

• DNA (Deoxyribonucleic acid) is the molecule that carries genetic information in all living organisms.
• DNA encodes specific traits or characteristics.

Nervous System

• The neuron is the fundamental cell of the nervous system that transmits electrical signals to other cells.

Biotechnology

• Genetic engineering involves the manipulation of an organism's genes to create new traits or characteristics.
• Bioremediation is the biotechnology concept that involves the use of biological processes to clean up environmental pollutants.

Cell Biology

• Cell biology is the branch of biology that deals with the structure, function, and behavior of cells.
• Cells use hormones to communicate with each other, regulating various cellular processes.

Ecology

• Ecology is the field of study that focuses on the interactions between organisms and their environment.
• An ecosystem is a group of interacting organisms in a particular habitat.

Political Science

• Autocracy is a political system characterized by the concentration of power in the hands of a leader or small elite.
• World War II was the global conflict that took place from 1939 to 1945 and involved the majority of the world's nations.
• Ancient Greece is known for its philosophy, democracy, and theatrical arts.
• The system of government in which powers are divided among different branches of government is known as federalism.
• The United Nations is the international organization established in 1945 to promote peace and cooperation among nations.
• Democracy is a form of government in which power is vested in the people, who rule either directly or through freely elected representatives.
• Anarchy in the context of international relations refers to the absence of a central authority or government.
• Realism in the context of international relations is a theory that focuses on the pursuit of power and security by nations.
• Multilateralism in the context of international relations refers to the cooperation and coordination of multiple nations to achieve a common goal.
• Political systems refer to the structures and institutions that govern a society.
