Explanation:

Double fertilization in angiosperms is a process that ensures both the formation of the embryo, giving rise to a new plant, and the endosperm, a nourishing tissue. Double fertilization is a process in which one gamete joins the oosphere, while another joins the polar nuclei. For this phenomenon to occur, a number of factors are required, which begin with pollination.

The result of double fertilization occurs when the male gamete merges with the female gamete called the oosphere, this fusion is responsible for giving rise to the diploid embryo, which can form a new individual. Already the gamete that fuses to the polar nuclei is responsible for giving rise to the so-called endosperm, which is triploid. In short, after double fertilization a zygote and an endosperm form.

the "dirty dozen" chemicals banned in an international treaty are formally known as persistent organic pollutants, or pops. the united nations environment program provided this background on what they are and what they can do to humans and wildlife.
