How are finches in the Galapagos island a good example of adaptation

Each species has a special beak adaptation.

Explanation:

Finches in the Galapagos Island are good example of adaptation because these finches have undergone several variations in their beak shape and form according to their ecological niche. The different beak forms were specialized for different functions like strong beaks were adapted for crushing hard seeds and birds with slender beaks were evolved for song production.

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.
