Other related sciences include microbiology and organic chemistry. The word science comes from a Latin word scientica, which means knowledge, or information. Science is a process of systematically gathering detailed information and gaining exact knowledge.

We do not know all the "life" information secrets but we are learning more every day. The three biological life cycle s, are; Zygotic meiosis, Sporic meiosis, and Gametic meiosis. Amoeba - one basic life form. Amoebas and there are many different kinds feed by phagocytosis the engulfing and ingesting of foreign particles or waste matter by phagocytes --they flow around their prey usually a smaller cell and engulf it.

Organism that eat other organisms are usually called "consumers". The amoeba's cell membrane then fuses with itself, trapping the prey in a "food vacuole" where it will be digested. In click to see more first place, no slight inconvenience results from too great separation beween branches of study which serve for the perfection of one art.

Biologists study life over a wide range of scales: As you can see there are far more than 25 branches of biology. There are also several related disciplines. Medicine -- Physical anthropology. Biology encompasses a broad spectrum of academic fields that are often viewed as independent disciplines.

Sometimes new knowledge comes simply from being in the right place at the right time or from being particularly aware of the unusual. The opposite of the scientific method and its organized planning is discovery by "accident". A hypothesis is a guess as to why something happens. Observations lead to questions regarding the event. Why is the sky blue?

How does gravity affect falling objects? In attempting to answer a question about the nature of the world, a scientist will form a hypothesis or a guess regarding the question's answer. Experiments, data gathering and study will then help the scientist to reach a conclusion. References for the Scientific Method: WATER - Living things are built almost entirely of organic compounds containing carbon, hydrogen, nitrogen, oxygen, phosphorus, sulfur, and water.

Water is vital to life because it forms the basis of many body fluids, it is 1998 Ap Biology Essay by structures such as seeds, and it controls temperature regulation.

Periodic Chart of the Elements with correlation to their health aspects - http: Taxonomy Detailed information and examples and links to database searches are found on our Microscopy Page Paragraph 3. All life forms are composed of basic chemical elements.

Atomic elements prefer to exist as molecules. Earth life thrives on water. Life is built up these Top Paper Editor Websites use some very common materials. There is one substance though that is more complicated and vital to life. A Dutch biochemist, named Mulder, first used the word "protein" in He got the word form a Greek word meaning "holding first place.

Although proteins are complicated they consist the elements of carbon, hydrogen, oxygen, nitrogen and sulphur. Some parts of the human body contain more than other parts but it exists is some amount in all parts of the body and it is vital for life to exist. There is no living organism that does not contain protein.

Viruses for example contain a complicated type of protein called nucleoprotein. When proteins are exposed to an acid the protein breaks apart into smaller molecules. These smaller molecules are called amino-acids. Millions of different proteins can be formed from the combinations of different amino-acid molecules.

Some common proteins are: Difference Patterson Tutorial; PR Enzymes control body chemistry. The enzymes of the human body work by means of surface catalysis http: That is the surface of the enzyme enables other molecules to react in a manner they would not without the surface of the enzyme present.

The enzyme being the catalyst is not changed in any manner from the action of the protein. The human body contains only a small quantity of enzymes but even this small quantity is sufficient.

They are important to many functions including food digestion. 1998 Ap Biology Essay an explanation of what an enzyme is 1998 Ap Biology Essay here http: Some, however such as egg cells of birds, can be seen with the naked eye.

Others, like nerve cells, may be very small in some of their dimensions, but extremely long; a single human nerve cell may be as much as 3 or 4 feet long, and an elephant's nerve cell may be even longer.

To say that cells are generally small is not saying much, however, because even among microscopic cells there is a wide range in size. Biologists took it for granted that cells are bounded by a membrane - the plasma membrane, as it is often called.

Cell image from http: The cell membrane is not simply 1998 Ap Biology Essay envelope giving mechanical strength and shape and some protection to the cell, though these functions are important. It regulates the traffic in materials between the precisely ordered interior of the cell and essentially unfavorable and potentially disruptive outer environment.

Usually portions of the cell flow around the material, enclosing it within a chamber. When the engulfed material is liquid or consists of very small particles, the process is often termed pinocytosis.
