Periderm is the corky outer layer of a plant stem which the plant creates as a result of an injury or infection so as to protect itself further. Protoderm is the thin layer which covers embryos, as well as the root and stems, and later produces epidermis, which is the outer layer of tissue of plants (anywhere where periderm doesn't cover them).
The correct answer is - C. -1.9 C degrees.
The sea ice in the polar oceans needs little lower temperatures to start forming than what it would need if it was't forming on a saline water. The freshwater starts freezing as the temperature goes bellow 0 C degrees, but that is not the case with the saline water. The saline water, because of the salt that prevents the freezing to a certain point, needs temperature of -1.9 C degrees to start freezing. Once this temperature is reached, the salt can not prevent the freezing anymore, so the water on the polar oceans starts to freeze.
