Gated channel in a cell membrane allows
a. osmosis.
b. simple diffusion.
c. active transport.
d. facilitated diffusion.

The best answer is D. Facilitated diffusion is a channel mediated diffusion and functions much like a bridge over a river that must raise and lower in order to allow boats to pass. When the bridge is lowered, boats cannot pass to the other side of the river. In a similar manner, a gated channel often remains closed, not allowing substances into the cell until it receives a signal (like the binding of an ion) to open. When this signal is received, the bridge (gate) opens, allowing the boats (substance) to pass through the bridge and into the other side of the river (cell membrane)

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.
