Fruits ripen due to an enzyme converting starch into sugar. Keeping fruits in the refrigerator slows this process. Which sentence explains why?
Enzymes are solar-powered, they
convert light energy into chemical
energy, which they hand down to
their substrate. The refrigerator is
dark once the doors are closed the
enzymes won't get enough energy.
The enzyme converting starch into
sugar catalyzes the reaction at 20°C
(room temperature) and the reaction
rate decreases at lower
temperatures.
The enzyme converting starch into
sugar switches substrates at lower
temperatures and then starts
catalyzing another unrelated
substrate.
The reaction rate is constant
regardless of the temperature, but
the concentration of starch decreases
at lower temperatures.

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.
