Which of the following statements is true? a. organ systems are more complicated than the organs, tissues, and cells that they are made from. b. two identical daughter cells are created by sexual reproduction. c. the dna in eukaryotic cells is spread throughout the cytoplasm. d. the cells of different organisms are very different in structure and chemical composition.

I would say that the answer is A.  Answers B and C are definitely wrong because DNA in eukaryotic cells are in the nucleus while two identical daughter cells are created from asexual reproduction. Answer D is wrong because you can compare two different organisms like a human and a dog. Since both are eukaryotic they will have eukaryotic cell structures with their organelles. I believe that A would be correct, if you remember the the level of organizations, then you know that cells are simple, as cells become tissues, they become a little complex, as tissues become organs, they get a little complex, finally when organ systems are formed, they are highly complex from the organs, tissues and cells. Hope that answered your 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.
