A) The source is probably not valid because it is based on an opinion.
He or she that wrote it did not go into a lab and see if the resources are true its just based on what he thinks it is.
Children's rights according to the constitution of the United States of America, are the human rights of children with particular attention to the rights of special protection and care afforded to minors.The 1989 Convention on the Rights of the Child (CRC) defines a child as "any human being below the age of eighteen years, unless under the law applicable to the child, majority is attained earlier." Children's rights includes their right to "association with both parents, human identity as well as the basic needs for physical protection, food, universal state-paid education, health care, and criminal laws appropriate for the age and development of the child, equal protection of the child's civil rights, and freedom from discrimination on the basis of the child's race, gender, sexual orientation, gender identity, national origin, religion, disability, color, ethnicity, or other characteristics." Which means that any child, indiscriminately of how many deserves the basic right of "association with both parents, human identity as well as the basic needs for physical protection" Removing one or more children from their homes because of their number would severely violate their human rights.
D. The percentage of muscle and body fat is often defined as the mass of the body which is why this is taken into account when measuring the BMI for children and teens. It might not use all of the fat, but some parts of it is needed to measure the mass effectively.
The answer is true, I hoped this helps!!
