Recently, researchers from stanford university have changed mouse skin cells into mouse nerve cells. this was accomplished by inserting genes that control the synthesis of certain proteins into the skin cells. this type of research is often successful in advancing knowledge regarding the functioning of human cells because
(1)cells present in humans often function in similar ways to cells present in other organisms
(2)cells from different types of organisms function differently when transplanted into humans
(3)the cells in all complex organisms contain the same genes and function in similar ways
(4)cellular research using mice can always be applied to human cells since all complex organisms produce the same proteins

I believe the correct answer from the choices listed above is option 4. This type of research is often successful in advancing knowledge regarding the functioning of human cells because cellular research using mice can always be applied to human cells since all complex organisms produce the same proteins.

Hope this answers the question. Have a nice day.

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.
