Document Summary
Life provides an interesting: illustration of two themes: transition and continuity. Development is the sequence of age-related changes that occur as a person progresses from conception to death. Reasonably orderly, cumulative process that includes both the biological and behavioural changes that take place as people grow older. Life span divided in 4 broad periods: prenatal period (between conception and birth, childhood, adolescence, adulthood. Conception occurs when fertilization creates a zygote. Zygote: a one-celled organism formed by the union of a sperm and an egg. All of the other cells in your body developed from this single cell. Each chromosome houses many genes (functional units in hereditary transmission) Prenatal period extends from conception to birth, usually encompassing nine months of pregnancy. Don"t grow at the same pace as prenatal stage after birth because the frenzied pace of prenatal development tapers off dramatically.
