Which of the following is a chromosomally transmitted form of intellectual disability caused by the presence of an extra copy of chromosome 21?

Down syndrome

Which statement is best supported by the results of current research?

bonding

The threadlike structures found in the nucleus of each human cell and made up of deoxyribonucleic acid are called

Which psychological approach emphasizes the importance of adaption, reproduction, and survival of the fittest in shaping behaviors?

Fertilization typically takes place in the

Which of the following outcomes are associated with fetal alcohol spectrum disorders? (Choose every correct answer.)

heart problems; learning problems; facial deformities

Interpreting the results of adoption and twin studies is difficult because of the complexities of

mitosis; meiosis
