question 3

what are two ways that permanent teeth differ from primary teeth?

Explanation:

Question 1

From ages 4 - 6, a child’s height typically increases by about 2 - 3 inches per year, and weight by 4 - 6 pounds yearly. Growth is steady but slower than toddler years. Muscles develop, and fat distribution changes, with a leaner appearance.

A 3 - year - old has a rounded tummy, short limbs, and a top - heavy look (large head relative to body). A 6 - year - old has a flatter tummy, longer limbs, better posture (more upright, less swayback), and a more proportionate body (head is smaller relative to body, limbs match torso length better).

1. Number and Type: Permanent teeth (32 total, including molars like 12 - year molars) outnumber primary teeth (20, no 12 - year molars). Permanent teeth have premolars (missing in primary set).
2. Size and Structure: Permanent teeth are larger (to last adulthood), have longer roots, and enamel is harder (more durable for lifelong use) than primary teeth.

Answer:

From ages 4 to 6, a child’s height usually increases by 2–3 inches per year, and weight by 4–6 pounds per year. Growth is steady (slower than toddler years), with muscle development and a shift toward a leaner body as fat distribution changes.
