This occurs when two sperm nuclei reach the interior of a female gametophyte, where one sperm will fertilise the egg cell to form a zygote, whereas the other usually fuses with the binucleate central cell, forming a primary endosperm cell, effectively constituting an organism separate from the growing embryo. Approximately 70% of angiosperm species have polyploid endosperm cells which are typically triploid (containing three sets of chromosomes), but can vary widely from diploid(2n) to 15n.
Answer:
Polarity causes water molecules to become attached to each other. Cohesion is also know as the attachment of 2 of the same substance
From the figure, it can be concluded that the process of precipitation, runoff and percolation are the three stages in which the water moves downward due to the influence of gravity. The precipitation occurs in the form of snowfall, rainfall, and so on. This allows the water to fall freely because of gravity
