Imagine a prometaphase chromosome pair that is attached to one spindle pole. which of the following would happen if both arms of the chromosome are severed with a strong laser beam?
a) all chromosome fragments (the centromere-containing fragment and the arm fragments) would be pushed away from the pole
b) only the two arm fragments would be pulled toward the pole. the kinetochore-containing fragment would remain stationary
c) the kinetochore-containing fragment would be pulled toward the pole. the two arm fragments would move away from the pole
d) the kinetochore-containing fragment would move away from the pole, but the two arm fragments would be pulled toward the pole
e) all chromosome fragments would be pulled toward the pole

（C）is the answer.

Explanation:

The direction of the force on the two fragment can be seen from the picture.

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.

if your own plato the answer is b. the fern transitioned from sporophyte generation to gametophyte generation.
