Cell maintain homeostasis through diffusion in isotonic solution. Isotonic means that the concentrations are the same on either side of the membrane, maintaining homeostasis.
What he said ^^. . . ....... . .
1 - V=150 cm3
2 - 180 divided by 150= 1.2 g/cm3
3 - The mass would stay the same on the moon as on Earth because mass is just how much matter is in an object. However, the weight would be different because the gravitational pull is weaker on the moon than it is on Earth.
4 - The density is greater than the density of water which is 1 g/cm3.
5 - No because one solid could be a heavier material than another solid.
9 - Mass: gram (g) or kilogram (kg). Volume: liter (L) or centimeter (cm). Density: g/cm3 or g/mL
