A.

assimilation.

B.

accommodation.

C.

scheme.

D.

disequilibrium.

Answer and Explanation

The Correct Answer is B

A. assimilation: Fitting new info into an existing schema without changing it (e.g., calling a bus a “car”); not what happens here.
B. accommodation: Modifying the schema (broadening “vehicle” to include buses, trucks, ships).
C. scheme (schema): The mental framework itself, not the process of change.
D. disequilibrium: Cognitive conflict that can prompt change; the change itself is accommodation.

A. Phenylketonuria (PKU): PKU is an inherited metabolic (single-gene) disorder and is not related to maternal age in the way chromosomal nondisjunction is.
B. Down syndrome: Down syndrome (trisomy 21) risk increases markedly with maternal age; it occurs far less often in births to mothers aged 16–34 than in older mothers.
C. Turner syndrome: Turner syndrome results from monosomy X (missing X) and is not strongly linked to maternal age in the same way as trisomy 21.
D. Sickle-cell anemia: Sickle-cell anemia is an inherited single-gene disorder (autosomal recessive) tied to parental carrier status, not maternal age.

Correct Answer is C

Explanation

A. fetal: Later period; more functional defects and growth issues than major structural ones.
B. implantation: Very early pre-embryonic stage; structural organ formation hasn’t begun.
C. embryonic: Weeks 3–8; organogenesis occurs, so risk of major structural defects is highest.
D. germinal: Conception to ~2 weeks; before organ formation, thus lower risk of structural anomalies.
