Step-by-step explanation:
Scoliosis MOST commonly affects adolescent females. Scoliosis is an abnormal, lateral curvature of the spine that can also involve compensatory curves to maintain balance. It is often observed to worsen during periods of rapid growth, such as during adolescence. The exact cause of scoliosis remains unknown; however, it could arise due to factors like muscular weakness, structural defects, or limb length discrepancies. While many individuals with scoliosis may not need treatment, options like a back brace for growing children or surgery in severe cases can be considered.
Regarding the question of which adolescents are least likely to be targeted for bullying, the least likely would be the captain of the football team. Typically, positions of high status within a school's social hierarchy, like being a sports team captain, can provide a level of protection against being targeted for bullying.
