Explanation:
The life process of initiating the development of a new entity of its kind through the fusion of male and female gametes is known as fertilization. The sperm from the male and the egg from the female unite forming the zygote, a structure containing crucial genetic information from the mother and father individually.
What Is Internal Fertilization?
Syngamy of gametes occurs inside the female body after insemination through copulation
Observed in birds, mammals, birds occurring in terrestrial plants and animals, also in some of the aquatic entities. This is observed in three ways – ovoviviparity(eggs retained in the female body, hatched when fully developed, oviparity(egg-laying), viviparity(offsprings develop within the female body)
Observes in plants such as bryophytes, pteridophytes
What Is External Fertilization?
Syngamy of gametes outside the female body/outer environment, notably in water bodies
Observed in few vertebrates, sea urchins, fish, aquatic invertebrates, almost all amphibians
Deposition of sperms and eggs by males and females in open surroundings is known as spawning
Broadcast fertilization – used when sperms swim through the water uniting with eggs to fertilize
Difference Between Internal and External Fertilization
Listed below are some significant differences between internal and external fertilization
Internal Fertilization External Fertilization
What is means
Fusion of gametes within the body of the female Union of the gametes in an external environment(Water bodies)
Quantity of gametes released
Lesser is released and deposited inside the body of the female Multiple gametes(both male and female) released into the external environment
Gametes involved
Only male gametes are discharged into the female genital tract Both female and male gametes are discharged into the external surroundings
Site of further development
Inside the female body Outside the body
Types
Viviparity
Oviparity
Ovoviviparity
No types as such, external environment
Merits
High survival chances as nourished by parent
Successful fertilization rate is high
Chances of success of survival in harsh conditions are high
Offsprings produced are many
Finding a mate requires less energy
Competition between parents and their offsprings is less
Demerits
Finding a mate requires much energy
Most of the contribution is from the female counterpart
Few offsprings produced
As they get preyed upon easily and lack of parental care results in lesser survival chances
Most of the offsprings go unfertilized, failing to survive until attaining maturity
Survival restricted to moist and wet environment only
Examples
Reptiles, Birds, Mammals, Tracheophytes, Pteridophytes Algae, Fish, Amphibians

Explanation:
Nationalism is an idea and movement that promotes the interests of a particular nation (as in a group of people),[1] especially with the aim of gaining and maintaining the nation's sovereignty (self-governance) over its homeland. Nationalism holds that each nation should govern itself, free from outside interference (self-determination), that a nation is a natural and ideal basis for a polity[2] and that the nation is the only rightful source of political power (popular sovereignty).[1][3] It further aims to build and maintain a single national identity, based on shared social characteristics of culture, ethnicity, geographic location, language, politics (or the government), religion, traditions and belief in a shared singular history,[4][5] and to promote national unity or solidarity.[1] Nationalism seeks to preserve and foster a nation's traditional cultures and cultural revivals have been associated with nationalist movements
