Some given statements about anti freezing are given;

a. some invertebrates to withstand temperatures as low as –18°C without freezing, in presence of glycoproteins

b. Sodium, potassium, or chloride ions involve to increasing  the blood freezing point, so the lack of these ions some species help to lower the blood freezing point

c. Amphibians release large amount of glucose into the blood to prevent freezing of blood in cold

d. Sodium, potassium or urea function as anti freezing in their blood

e. Glycine causes supercooling in plants
