Answer:
The life cycles of all sexually reproducing plants follow a pattern of alternation between a haploid, sexual generation called gametophyte with a diploid, asexual generation called sporophyte.
This phenomenon of alternation between gametophyte (n) and sporophyte (2n) in the life cycle of a plant is called alternation of generations (Hofmeister, 1851).
Alternation of generations is of two types- isomorphic and heteromorphy. In isomorphic (or homologous) type both the alternating generations are morphologically similar, while in heteromophic (or heterologous) type of alternation of generations both the generations of life cycle are morphologically dissimilar.

Answer:
Due to global warming.
Explanation:
Many scientists think that the winter weather near the Western European coast might change in the coming future because of global warming. The global warming is the main factor of changing the weather condition all over the world due to increasing of earth's temperature. This warming of earth surface make the winter less colder and increases the temperature of the winter season so that's why scientist think that increase in temperature occurs in the winter weather of Western European coast.
