__What is an organism?__ An organism is a form of life that could be a plant an animal bacteria ect.

__**History Of Science**__ question: How did each early civilizations explain biological diversity? answer:early scientists believed that the huge variety of different organisms on earth were created by god. Classification- The process of organising organisms into groups based on predetermind criteria is called classification.The classifiction of living things is said to be strong,multilevel classification,strong,multievel classification.strong because the shceme gives predictable results.multievel because major groupings may be further subdivided into smaller subgroups. the criterion we use to assign organisms to groups is the closess of the evolutionary relationships between members of the group.this is usually observed by looking at the number of the features shared by organisms when we compare them.Features that might be used when looking to group organisms could include: (1) Physical structures (eg.anatomy of bones,teeth,organs) (2)biochemistry(eg.protein similarities) (3)manner of development (4)behavioural characteristics (5)similarities in DNA

This is my five kingdoms activity describing the different features.

Hierarchies of organisations Organisms have the following levels of organizations: system, skeletal system, muscular system, nervous system, digestive system , excretory system, endocrine system, reproductive, system, and lymphatic/immune system =__//Glossary//__=
 * __1-Atom__**:Apart or particle considered to be an unbreakable constituent of a specifiedsystem.
 * __Example__**: hydrogen,oxygen, gold, aluminium, neon, silver, carbon, potassium
 * __2-molecules:__**thesmallest particle of a substance that retains the chemical and physicalproperties of the substance and is composed of two or more atoms; a group oflike or different atoms held together by chemical forces.
 * __Example:__** .CO2 – carbon dioxide, H2O – water, NaCl –salt and H2 - hydrogen. //Biology// Thesmallest structural unit of an organism that is capable of independentfunctioning, consisting of one or more nuclei, cytoplasm, and variousorganelles, all surrounded by a semipermeable cell membrane
 * __Examples:__**Stem cells are biological cells found in all multicellular organisms.
 * __4-tissues:__** tissue is a cellularorganizational level intermediate between cells and a complete organism. A tissue is an ensemble of cells, not necessarilyidentical, but from the same origin, that together carry out a specificfunction.
 * __Example:__** Epithelial Tissue. ConnectiveTissueMuscleTissue. NerveTissue
 * __5-organs__**: isa collection of tissues joined in structural unit to serve a common function
 * __Example:__** liver,lung and intestines.
 * 6-organ systems:**Thefunctions of organ systems often share significant overlap. For instance, thenervous and endocrine system both operate via a shared organ, the hipothalumis.For this reason, the two systems are combined and studied as the neuroendocrinesystem. The same is true for the muscular skeletal system, which involves the relationship between the muscular and skeletal systems
 * __Example:__** cardiovascular/circulatory


 * Trait**:a trait is a noticable or significant feature that somebody has.everyone has different traits thsat ake us all look different/unique.traits are passed on down in families-this includes any big illnesses such as cancer and heart disease.

__**Single gene traits include-**__ Tongue rolling Free ear lobe Hand clasping hitchhikers thumb Bent little finger Widows peak Dimpled chin Mid-digital hair Pigmented irises darwin turbicle frekles more than five fingers dimples wooly hair long eyelashes short big toe.
 * hereditary traights:** we inherit our genes from our parents.the passing of genes from our parents is called hereditory traits.
