They are this way because they have to keep oxygen in the cabins, they are at great altitudes so there’s a lack of oxygen and warm temperatures. If these systems failed the oxygen masks would drop and the cabins would drop in temperature, but it wouldn’t occur at a fast rate.
All organisms need food for the energy required to live and grow. They all excrete (get rid of) waste products, and detect changes in their surroundings and respond to them. All living organisms follow a LIFE CYCLE of growth and development, reproduction, and death.
Answer:
Separation of sister chromatids and centromeres.
Explanation:
Once chromosomes align along equatorial plate during metaphase of mitosis, the next step of mitosis is separation of the sister chromatids and the centromeres. The separation of sister chromatids and the centromeres occurs during anaphase of mitosis. During this phase, spindle fibres which are produced from centrioles in the centrosome at two opposite poles of the cell, attach to the centromere region of the chromosomes and drag each sister chromatid of the chromosome apart towards opposite pole of the cell. This is how each opposite pole receives one chromatid from each chromosome. Later during telpophase of mitosis, cytokinesis occurs which produces two daughter cells with equal number of chromatids.
