Some climates have temperatures that drop below the freezing point of water for several months. Which of the following is a unique property of water that allows life on earth to exist in aquatic environments in these types of climates? a. The melting and freezing points of water shift based on latitude, allowing it to stay in liquid form longer in higher latitudes.
b. The density of water changes when it freezes so solid water is less dense than liquid water.
c. Water has adhesive properties that lower its freezing point allowing it to stay in liquid form longer.
d. Water has a high boiling point allowing it to evaporate and condense into clouds providing more liquid precipitation.

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.
