Fear

Fear is a feeling induced by perceived danger or threat that occurs in certain types of organisms, which causes a change in metabolic and organ functions and ultimately a change in behavior, such as fleeing, hiding or freezing from perceived traumatic events. Fear in human beings may occur in response to a specific stimulus occurring in the present, or in anticipation or expectation of a future threat perceived as a risk to body or life. The fear response arises from the perception of danger leading to confrontation with or escape from/avoiding the threat (also known as the fight-or-flight response), which in extreme cases of fear (horror and terror) can be a freeze response or paralysis.

In humans and animals, fear is modulated by the process of cognition and learning. Thus fear is judged as rational or appropriate and irrational or inappropriate. An irrational fear is called a phobia.

Psychologists such as John B. Watson, Robert Plutchik, and Paul Ekman have suggested that there is only a small set of basic or innate emotions and that fear is one of them. This hypothesized set includes such emotions as joy, sadness, fright, dread, horror, panic, anxiety, acute stress reaction and anger.

Sex

Organisms of many species are specialized into male and female varieties, each known as a sex.Sexual reproduction involves the combining and mixing of genetic traits: specialized cells known as gametes combine to form offspring that inherit traits from each parent. Gametes can be identical in form and function (known as isogamy), but in many cases an asymmetry has evolved such that two sex-specific types of gametes (heterogametes) exist (known as anisogamy).

Among humans and other mammals, males typically carry XY chromosomes, whereas females typically carry XX chromosomes, which are a part of the XY sex-determination system. Other animals have a sex-determination system as well, such as the ZW sex-determination system in birds, and the X0 sex-determination system in insects.

The gametes produced by an organism are determined by its sex: males produce male gametes (spermatozoa, or sperm, in animals; pollen in plants) while females produce female gametes (ova, or egg cells); individual organisms which produce both male and female gametes are termed hermaphroditic. Frequently, physical differences are associated with the different sexes of an organism; these sexual dimorphisms can reflect the different reproductive pressures the sexes experience.

Film

A film, also called a movie, motion picture or photoplay, is a series of still images which, when shown on a screen, creates the illusion of moving images due to the phi phenomenon. This optical illusion causes the audience to perceive continuous motion between separate objects viewed rapidly in succession. A film is created by photographing actual scenes with a motion picture camera; by photographing drawings or miniature models using traditional animation techniques; by means of CGI and computer animation; or by a combination of some or all of these techniques and other visual effects. The word "cinema", short for cinematography, is often used to refer to the industry of films and filmmaking or to the art of filmmaking itself. The contemporary definition of cinema is the art of simulating experiences to communicate ideas, stories, perceptions, feelings, beauty or atmosphere by the means of recorded or programmed moving images along with other sensory stimulations.

The process of filmmaking is both an art and an industry.

Nigerians

Nigerians or Nigerian people are citizens and/or people with ancestry from Nigeria. Nigeria is composed of multiple ethnic groups and cultures and the term Nigerian refers to a citizenship-based civic nationality. Nigerians derive from over 250 ethnic groups and languages. Though there are multiple ethnic groups in Nigeria, economic factors result in significant mobility of Nigerians of multiple ethnic and religious backgrounds to reside in territories in Nigeria that are outside their ethnic or religious background, resulting in the intermixing of the various ethnic and religious groups, especially in Nigeria's cities. The English language is the lingua franca of Nigerians. About 50 percent of Nigerians are Muslims and the other 50 percent are Christians.

Nigerians come from multiple ethnic and religious backgrounds as the creation of Nigeria was the result of a colonial creation by the British Empire that did not correlate with ethnic and religious boundaries.

There have been several major historical states in Nigeria that have influenced Nigerian society via their strong kings and their advanced legal and taxation systems, and the use of religion to legitimize the power of the king and to unite the people. Northern Nigeria has been culturally influenced by Islamic influence including several major historic Islamic states in the region. The Kanem-Bornu Empire and the Sokoto Caliphate were major historical Islamic states in northern Nigeria. Southern Nigeria historically held several powerful states, including the Benin Empire and Oyo Empire, Ife Empire and several other Yoruba states.
