LIFESPAN EXAM 1 STUDY GUIDE Dependent variable: the factor that can change Independent variable: the manipulated factor, the potential cause Correlation: relation, not causation, measured by correlation coefficient anywhere from -1 to +1 An organism’s entire genetic inheritance: genome/genotype Chromosomes of males: XY Chromosomes of females: XX Monzygotic twins: Identical twins Dizygotic twins: Fraternal twins Teratogen: agents and conditions, including viruses, drugs, chemicals, stressors, and malnutrition, which can impair prenatal development and lead to birth defects or even death. For physical defects, the critical period is the entire period of the embryo. Apgar: Scale used to assess newborns at 1-5 minutes after birth.

Transient exuberance: brain growth rapid, seen in dendrites Pruning: Underused neurons are inactivated or “pruned” Genotype: all genetic material — internally coded, inheritable information Phenotype: observable expression of the genetic material Down syndrome: trisomy 21—extra chromosome causes mild retardation and physical abnormalities Genetic disorders in dominant gene are frequently expressed. Age of viability: 24-25 weeks or 6 months in utero...

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
