Body composition refers to a person's overall weight. D. Lean body mass is the nonfat component of body composition. Please select the best answer from the choices provided. A b c d.
Answer:
Too much body fat can lead to joint or bone disorders.
The statement that is incorrect is body composition refers to a person's overall weight. The correct option is C.
What is body composition?The relative proportions of fat, muscle, bone, and other tissues in the human body are referred to as body composition.
It is a measurement of how much of a person's body weight is made up of fat, lean tissue (like muscle and bone), and other types of tissues.
Body composition, rather than a person's overall weight, refers to the relative proportions of fat and non-fat mass (such as muscle, bone, and organs) in the body. As a result, option C regarding body composition is false.
Option A is correct because excess body fat can put extra strain on joints and bones, resulting in joint or bone disorders.
Option B is correct because body composition is influenced by a variety of factors, including genetics, age, gender, diet, and physical activity.
Thus, the correct option is C.
