Biology

Introduction
Biology means the study of life.  Biologists study various organisms.  Biology has a long history.  Artistole is the first biologist I know of.  There are categories that show the relationship between organisms.  Kingdom, phylum, class, order, family, genus, species are the categories.  There are 5 kingdoms.  Biology has many subtypes.  It is a sweet science.
History
Alcmaeon was the first person to dissect humans.  He was looking for the organ of intelligence.  He discovered the optic nerves and eustachian tubes.  Aristotle was the first European taxonomist.  He learned about animals in the sea.  Theophrastus studied planets and wrote books about it.  William Harvey did a lot of dissections on animals.  He found out a lot about the heart and wrote a book about it.  The rest is history.
5 Kingdoms
Bacteria- They're a type of single-celled organisms that have a cell wall.  They lack organelles.  They live everywhere and they may be the oldest lifeforms on earth.  They reproduce asexually.

Protist- They're a type of single-celled organisms and they have organelles.  This is the most diverse kingdom.  They are similar to all the other kingdoms.  This is my favorite kingdom.  They mostly reproduce asexually; a few of them screw.

Fungus- Some are single-celled, others are multicelled organisms.  They feed off dying plant material. Some reproduce by sexual reproduction.  Depending on species.

Plants- They are a type of multicelled organism.  They eat sunlight, drink water, and breathe carbon dioxide.  They are food for animals and fungi.  They all reproduce by sexual reproduction. 

Animals- Are a type of multicelled organisms.  They all move around unlike plants.  This is the kingdom humans are part of.  They have most complex consciousness.  They all reproduce by sexual reproduction.  
Subtypes
Microbiology: The study of microorganisms (bacterium, protists, fungi).
Zoology: The study of animals.
Botany: The study of plants.
Mycology: Study of fungi.
Evolutionary Biology: The study of how organism evolves.
Astrobiology: The study of extraterrestrial organisms.
Chronobiology: The study of how time affects organisms.
Embryology: The study of embryos.
Immunology: The study of the immune system.
Parasitology: The study of parasites.
Conclusion
Biology can teach you a lot about yourself and the world around you.  It is a great science.  It can help us improve.  It is amazing.
