Answer:
...a force acts upon it.
Explanation:
"An object in motion tends to stay in motion unless a force acts upon it."
This same rule implies to running water. Water typically runs from a higher place to a lower place with the usage of gravity (except for certain rare cases). Until there is something blocking (for example, a dam, or a let down in the steepness of the drop), the water will continue to move forward.

The answer is the nucleus
Explanation:
Proglottids are segments in cestodes that contain bot the male and female reproductive organs. These segments go ahead to make eggs and then dettach form the worm. They are excreted and become agents of infection on the next hoist. Proglittids formed near the neck of the worm are immature while those at the tail end are literally bags of mature eggs.
The scolex is the head of the worm that is attached to the host. It is also the part that ‘sucks’ nutrients from the host. It has hooks that it uses to anchor itself in the host. In some species, rather than hooks, there are suction-cups that use suction for anchorage.
