Not quite. C is correct.

Studies of twins reared apart show that identical (monozygotic) twins are substantially more alike in habits, hobbies, and traits than fraternal (dizygotic) twins, highlighting genetic contributions.

A: why it's wrongResearch demonstrates that sharing 100% of genes yields significantly greater behavioral similarity than sharing roughly 50% of genes.

ApplicationHardInfant Learning and Cognition

An infant exhibits a decelerated heart rate when a novel tone is introduced. Over 20 consecutive repetitions, heart rate changes diminish and return to baseline. On trial 21, the volume of the tone is significantly lowered. The infant's heart rate will most likely __________ because of __________.

Why

Not quite. A is correct.

Heart rate deceleration reflects the infant orienting response to novel stimuli. When a familiarized stimulus changes, the infant notices the difference, resulting in dishabituation (a renewed decrease in heart rate).

A: why it's wrongA drop in infant heart rate signifies an orienting/attentive response; detecting a change in volume causes dishabituation (renewed attention), triggering another heart rate deceleration.

B: why it's wrongInfants typically demonstrate heart rate deceleration, not acceleration, when orienting to a newly noticed auditory change.
