Select one false statement regarding diffusion: diffusion is the movement of particles from high to low concentration substance a (molecular weight 120) will diffuse faster than substance b (molecular weight 240) solute in solution will diffuse faster if the solution is heated the source of energy for diffusion comes from cellular atp all of the above are true

The source of energy for diffusion comes from cellular ATP

Explanation:

Diffusion is the net movement of particles against concentration gradient. Particles move from higher concentration to lower concentration on their own without requirement of external energy source. Hence no ATP is required for the process. ATP provides energy for movement of particles against the concentration gradient.

Rate of diffusion increases with increase in temperature as kinetic energy of particles increases; also lighter the particles, faster they will move. Hence, a substance with less molecular weight will diffuse faster than heavier substance.

answer: grassland biomes are closer to the equator and receive more rain.

grasslands are biomes that are dominated by grasses rather shrubs and trees. savanna are biomes that exhibit grasses, shrubs and small tree as vegetation. grasslands are located near the equator of the earth. these are found in north america. savanna biomes are found in africa, south america, australia and india. grassland exhibit moderate climatic conditions, it receives   amount of rainfall higher than savanna.   therefore, savanna exhibit dry and hot climatic conditions.

the atomic number of magnesium is 12. its nucleus must contain 12 protons and no electrons. the atomic number of an atom is determined by the number of protons.

magnesium is an electrolyte injection commonly used to treat low magnesium levels in your blood. it is also used to prevent or control seizures in women with preeclampsia or eclampsia.
