True or False: Both males and females gain weight throughout adolescence, but this is not always accompanied by an increase in height.

The statement is true because during adolescence, significant changes occur in the body composition of both males and females. It's common for individuals to experience gains in body weight due to increased muscle mass and fat accumulation as they go through puberty. However, not all weight gain is accompanied by an increase in height for everyone. Factors such as genetics, nutrition, and overall health can influence growth patterns and may result in weight gain without a corresponding increase in stature.

The assertion in the question implies a more generalized understanding of adolescent development, which includes variations among individuals. During this period, the growth spurts do not always occur simultaneously with weight gain, leading to unique patterns in how each individual develops. Thus, recognizing that both males and females experience changes in weight without guaranteed increases in height leads to the conclusion that the initial statement is indeed accurate.
