Astudent is looking at a paramecium sp. using a compound light microscope. she turns the iris diaphragm to adjust

the brightness by controlling the amount of light beaming through the image

the objective lens and increase the magnification of the image

the electrons beamed through the image to regulate the brightness

the position of the paramecium sp. on the slide in order to center it for maximum magnification

I believe the correct answer from the choices listed above is the first option. A student is looking at a Paramecium sp. using a compound light microscope. She turns the iris diaphragm to adjust the brightness by controlling the amount of light beaming through the image. Hope this answers the question.

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.

Characteristic expected of mineral from lava at earth's surface

phaneritic textures in which phaner means visible so phaneritic textures are standard of impertinent volcanic rocks. these rocks crystallized gradually under the surface of earth. when the magma cools deliberately then the ores have chance to develop and produce long crystals.
