Explanation:
The defining characteristic of a water cycle is that it has the same starting and ending point. The water cycle is also known as the hydrologic cycle. It shows the cyclic path through which water moves in nature.
- The water cycle is a part of the biogeochemical cycle.
- The biogeochemical cycle shows how certain elements and compounds moves between living organisms and the earth.
- All living organisms are essentially dependent of water and it is exchanged with the environment around.
- Some key components of the water cycle are precipitation, ocean, living organisms, ground water, infiltration, surface run off, evaporation etc.

The vascular cambium produces secondary phloem and xylem tissue.
<span>Vascular cambium, a plant tissue located between the xylem and the phloem in
the stem of a vascular plant. It is also the source of both secondary xylem growth
and the secondary phloem growth. Vascular
cambium is usually found on dicots and gymnosperms not on monocots which
usually lack secondary growth. It does not transport water, dissolved food or
minerals by plants. </span>
<span>Vascular cambia are cylinders of unspecialized meristem cells which
divide to make new cells which
specialize to form secondary vascular tissues.</span>

Explanation:
MPF is a protein kinase. It catalyzes the transfer of a phosphate group from ATP to target proteins.
One of the pathways which are stimulated by the MPF is an enzyme that destroys cyclin. This means it stimulates the cyclin pathway. As mitosis gets initiated, the enzyme that breaks down cyclin becomes activated, and levels of cyclin start to be dropping down. The declining levels of cyclin lead to reduced levels of the MPF.
