During toddlerhood, what is the first sign that a child may be ready for toilet training?
A) Ability to walk independently
B) Sphincter control and brain maturation
C) Crying when wet
D) Walking up and down stairs
B) Sphincter control and brain maturation

What major physiological change begins in females during puberty?
A) Spermarche
B) Menarche
C) Growth spurt in muscle mass
D) Development of facial hair
B) Menarche

Which hormone stimulates the development of eggs in females during puberty?
A) Testosterone
B) Progesterone
C) Follicle-stimulating hormone (FSH)
D) Luteinizing hormone (LH)
C) Follicle-stimulating hormone (FSH)

During adolescence, which part of the brain is responsible for decision-making and impulse control?
A) Hippocampus
B) Amygdala
C) Prefrontal cortex
D) Cerebellum
C) Prefrontal cortex

D) Protein
C) Iron
Rationale: Iron is critical for females during adolescence due to the blood loss that occurs during menstruation, making it necessary for preventing anemia.

B) No change in heart and lung capacity
C) Increase in size and capacity of the heart and lungs
D) Temporary decrease followed by an increase in capacity
C) Increase in size and capacity of the heart and lungs
Rationale: During adolescence, the heart and lungs increase in size and capacity, leading to improved strength and endurance.
