When you move material across the cell membrane from an area of high concentration to an area of low concentration.

1. Passive Transport
2. Active Transport

Passive Transport

Explanation:
When rolling a wagon up a hill, it would require more energy (activity) to get to the top; this is similar to moving from a low concentration to a higher. When rolling down a hill with a wagon, it would be more easy (passive); this is similar to moving from high to low concentration.

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.
