Because of earths magnetic field and atmosphere
Answer:
<em>The correct option is D) Cities can be built in otherwise uninhabitable places.</em>
Explanation:
The advances in technology for transporting water has now allowed us to inhabit lands in which previously life was not possible because of the lack of water. Nowadays, perfectly clean and sterilized water is available to any house hold at any place due to the effective technologies of transporting water. Cities can be built in places which were uninhabitable previously due to the lack of water resources.
The
answer is ‘they create tension by pulling toward opposite poles’. Kinetochores change
between persistent phases of movement towards the pole (poleward) or inversed
(anti-poleward), which are coupled with alternating states of kMTs (kinetochore
microtubules) depolymerization and polymerization, respectively. A low tension
at kinetochores promotes change towards kMTs depolymerization, and high tension
promotes change towards kMTs polymerization.
