Which of the following correctly names and explains the significance of the phase of meiosis depicted below?
an image depicting a stage of meiosis. homologous sets of four chromatids along the center of the cell. spindle fibers from opposite poles have attached to each set of sister chromatids as well as the homologous sets.
anaphase i: separation of sister chromatids must occur to increase genetic diversity
telophase ii: each pole must form a haploid pair of chromosomes to begin dna replication
interphase ii: a daughter cell must prepare for a second phase of chromosome replication
metaphase i: spindle fiber attachment must occur for cell division to occur.

After reading the paragraph below, answer the questions that follow. researchers have created a robot that has a very thin leg that is moved by cardiac (heart) cells contracting in unison. the robot, made of a polymer similar to that used in making contact lenses, is bathed in heart cells with supporting cells, which then attach to the robot and provide movement as they contract. all of the cardiac cells working together can cause the robot leg to move in a way that individual cells could not. this is an example of a. emergent properties of cells. b. energy flow through an ecosystem. c. adaptation. d. internal environment regulation.

Which statement best describes a typical difference that could be found between the "analysis" and "conclusion" sections of a lab report? a) only the "conclusion" describes errors that occurred during the experiment, and only the "analysis" section suggests further research.b) only the "analysis" section includes specific data comparisons, and only the "conclusion" section suggests further research.c) only the "analysis" section discusses whether the original hypothesis was supported, and both sections include graphs of data.d) only the "conclusion section discusses whether the original hypothesis was supported, and both sections suggest further research.(the answer is b i just took the test)
