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

Which of the following is the correct prediction about the relative water content or RWC?

a.RWC is involve to measure of turgidity and water contents of plant cell

b.To estimate RWC, three measurements are needed: fresh weight, turgid weight, and dry weight

c.In drought condition, plant will die if the RWC values is less than 100%

d.RWC values closer to 100% indicate plants are less affected by drought stress
