Final answer:
The statement describes the normal physical development changes that occur in late childhood, which include body slimming, leg growth, neck elongation, and torso changes, hence the statement is true.
Step-by-step explanation:
The statement describes a phase of child growth and development typically seen during late childhood. This period involves the transition from younger, more rounded childhood body shapes to leaner and more proportional pre-adolescent forms. Children's bodies become straighter and slimmer, with a noticeable growth in leg length, elongation of the neck, and changes in torso shape. They indeed lose the baby-like appearance and start to resemble older children. These changes are consistent with normal human growth patterns and are a natural part of physical development as a child progresses towards puberty.
During this time of development, children also develop new motor skills, lose their primary (baby) teeth, start school, and become more socially independent. However, this process does not include bone completion in their development, which continues into adolescence and early adulthood, nor does it involve a rapid increase in body fat, which is more characteristic of infancy or the adolescent period depending on sex and individual. Therefore, based on normal patterns of growth and development, the statement is true.
