Which of the following statements is/are true about microscopes? (mark all correct responses)
the "working distance" for compound microscopes and dissecting microscopes is the same for both types of scopes, so you can use either type of microscope when examining any specimen
the amount of light illuminating a sample being examined under a compound microscope can be adjusted by adjusting the iris diaphragm and the condenser
since our microscopes are parfocal and parcentered, only minor adjustments to focus and position of the sample are necessary as we go from lower magnifications to higher magnifications
in a compound microscope, the total magnification of a sample is calculated by multiplying the magnification of the eye piece (usually 10x) by the magnification of the objective lens (4x, 10x or 40x)
when using a compound microscope, the coarse focus is used to bring a sample into focus at all levels of magnification

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.
