Education for children of migrant workers often presents a dilemma: Urban public schools tend to charge steep non-resident fees that low-paid migrant parents cannot afford, so they must often choose between unregistered, quasi-legal classrooms- set up by individuals without the aid of the state-or sending children back to their hometowns to be educated in the local school system where they have their hukou.

This forced tree-dwelling animals to adapt to their new environment or die out.

Bone remodeling appears to be governed by a feedback system in which the bone cells sense the state of strain in the bone matrix around them and either add or remove bone as needed to maintain the strain within normal limits.
