Explanation:
pollen grain sticks to the stigma, where the pollen build up a pollen tube to the ovule, after fertilization the ovary then builds up to develop into a fruit, depending of the the type of flower the fruit can be determined
An adaptation occurs when a species is set through a new constraint. This can be change in climate, defense mechanisms, food source, etc. Which will have to occur before an adaptation is made. For an example: in North America the climate slightly swifted. This meant smaller mammals such as rabbits would need to have a thicker coat of fur or shelter. Let's say all the thin furred rabbits died and all that remained were the thick furred rabbits. Over a span of time the rabbits have adapted through the climate. Meaning most of the population is thick furred through their DNA. Conclusively, it's a genetic characteristic that can happen very rapidly or slowly.
I hope this solved your question!
ANSWER
A water molecule consists of one oxygen atom bonded to two hydrogen atoms by covalent bonds. Since oxygen is more electronegative as compared to hydrogen atoms, the shared electrons are attracted towards the oxygen atom. This imparts partial negative charge to the oxygen atom and partial positive charge to hydrogen atoms. The overall effect is making the water molecular a polar one. The presence of free hydrogen atoms makes water molecule to form hydrogen bonds with other water molecules and with other polar molecules.
