Humans are able to produce 20 different amino acids, which have side chains with differing properties. How does the variation in amino acids' side chains affect a cell? It allows for a wide variety of proteins to be produced that will carry out a wide variety of functions.
It causes the cell to produce a wider variety of proteins that all carry out the same function within the cell.
It requires the cell to acquire more energy to accommodate a wider variety of chemical bonds among side chains.
It results in individual proteins that can each carry out a wide variety of biochemical processes within the cell.

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.
