What is the difference between osomosis and diffusion? a.) osomosis moves molecules, such as water, through a semipermanent membrane, diffusion moves molecules, such as oxygen and carbon dioxide, through a permeable membrane. b.) osomosis allows all molecules to move from areas of higher concentration to areas of lower concentration, division allows only water molecules the move from areas of higher concentration to areas of lower concentration. c.)osomosis requires facilitation by a channal protein, defusion requires additional energy from and energy carrying molecule like atp. d.)osomosis i’ll cruise over an area called a concentration gradient, diffusion occurs over a membrane bilayer.

For a family dinner, jose’s mom baked a loaf of bread. during the meal, his grandmother commented, “this bread is so dense! ” what do you think his grandmother meant by the word dense? you have some ideas regarding density already, but this experiment will enrich your understanding of the relationship between mass, volume and the density of objects. when making measurements in this experiment we will be using si units, the international system of units. the purpose of using si units is to have the ability to communicate and compare data results with other experiments without having to make conversions. measurement symbol si unit length m meter mass kg kilogram volume l liters density kg/l kilograms per liter any calculations that are performed during this experiment will ultimately be reported in scientific notation. recall that scientific notation is extremely important when we have data that is extremely small or large. scientists rely on a standard form of communication to quickly make hypotheses and judgements based on data. what is the density of block a? a0kg/l what is the density of block b? a1kg/l what is the density of block c? a2kg/l what is the density of block d? a3kg/l what is the density of block e? a4kg/l which block is the densest? a5
