Tne left ShowThe figure below shows a centrosome with microtubules attached to the kinetochore. Which of the following BEST describes the figure? O The figure shows an impossible arrangement due to microtubule dynamic instability. O The figure shows a temporary arrangement; soon after this, the microtubules will separate the sister chromatids. O The figure shows an impossible arrangement due to centrosome positioning. O The figure shows a temporary arrangement; soon after this, microtubule shortening will occur.Please ASAP Consider a diploid species with a deploid number 2. Show your work and explain your part. A. If a typical haploid gemete from this species contains DNA with a mass of 36 picograms of DNA would be in a typical somatic cell in G1 of the cell cycle?

Which of the following can we NOT conclude? O A. Both plants and animal cells spend most of their time in interphase, doubling all of the organelles and DNA requires a lot of time. OB.Animal cells spend more of their time in mitosis (dividing the nucleus) than plant cells do. O C. Plant cells spend more time in interphase and telophase than animal cells and animal cells spend more time in prophase, and anaphase than plant cells. OD. Plant cells divide more quickly than animal cells.cell type: 9) Label the figure below.
