Covalent bonds place constraints on the shapes of biological molecules. as the size and complexity of a biomolecule increases, the chemical focus shifts from covalent bonds to noncovalent interactions. noncovalent interactions dictate the stable, native conformations of large macromolecules and polymers while permitting the flexibility necessary for their biological functions. what characteristics of weak noncovalent interactions enable the assembly, stability, and functions of biomolecules?

The characteristic of the weak non covalent interactions that enable the assembly, stability and functions of bio molecules is that NON COVALENT INTERACTIONS HAVE LARGE AGGREGATE STRENGTH WHEN MULTIPLE INTERACTION ARE PRESENT. 
Although they are considered as weak forces, but when present in large number, non covalent interaction has the capacity to stabilize large polymers using their aggregate strength.

Schools are being forced to embrace computers. unlike their "digital immigrant" teachers, these students are "digital natives", born into a world where technology is an integral part of everyday life. almost every student has access to a multitude of computers, laptops and tablet devices. it would be crazy to assume an assignment would  notbe written on computer in this day and age.many schools now have a 1-to-1 computer policy, and many districts and states in the united states have mandated computers or ipads across the state for every student,  including los angeles, the second largest school district in the country.but the thing is, when they tried it in la, it wasn't the success they hoped for. that's because the tablets weren't used as much as they expected. rather, it appeared there was a gap between the digital native's love of technology and their use of it in the classroom.this conflicted relationship with computers is also underscored by much of the literature on education. it is also highlighted in professional development and conferences such as  edutech.
