wrote about the death of socrates

Remembered for his ruthless study of symptoms(symptomatology).First said that thoughts come from the brain not the heart.Though the body was comprised of four fluids( yellow bile,black bile,blood and phlegm.

• healthy individuals felt well because within their bodies are four fluids or humors.We feel well when the fluids are in balance.

• when out of balance we feel ill

• This notion set the stage for the modern notion of homeostasis

seeks to return the practice of human cadavers to study.Incurs the wrath of both the church and the humanist.Said that the best way to become a physician is to do your own dissection

• life is the orderly functioning of genes producing enzymes,which enable us to live

• The theory or doctrine that life processes arise from or contain a nonmaterial vital principle and cannot be explained entirely as physical and chemical phenomena.

• Humans have to make their existence to well-Known landmarks to wit,birth and death.

Characteristics of life

• Order:living organisms are complex

• Regulation:

• have the ability to grow and develop

• ability to process energy(light:heat)

• Irritability:Living organisms respond to their environment

• whenever changing from one form of energy to another heat is always released.

• Reproduction:The ability to perpetuate the species

• offspring are identical to original cell or organism

• involves inheritance of all genes from parent

• offspring are similar to parents,but show variations in traits

• involves inheritance of unique sets of genes from two parents

A cell or an organism having half of the number of chromosomes in somatic cells.

A cell or an organism consisting of two sets of chromosomes: usually, one set from the mother and another set from the father. In a diploid state the haploid number is doubled, thus, this condition is also known as 2n.

A groove formed from the cell membrane in a dividing cell as the contractile ring tightens.

any chromosome that is not the sex chromosomes, meaning (X or Y)

homologous:is a set of one maternal chromosome and one paternal chromosome that pair up with each other inside a cell during meiosis.

Genotype

an association between two organisms in which one (e.g., a mite) travels on the body of another, without being a parasite.

This describes a situation where there is (apparently) no selection pressure for or against a given trait.

• Natural selection

• Genetic drift
