Why is a suspension cloudy?
Egg white suspension is made up of a long molecule made up out of amino acids this why but don't ask how I have no clue :)
Which property of water results in a meniscus?
Adhesion due to the polarity of the water molecule.
How does a cell move a molecule that is too large transport proteins?
The cell membrane folds around the molecule.
What molecule is a membrane component?
lipids
What has more particles an atom or a molecule?
an atom is a molecule you dingbat
What structure is the statement below most likely referring to A large glucose molecule requires facilitated diffusion but an oxygen molecule does not?
A large glucose molecule requires facilitated diffusion but an oxygen molecule does not is a semipermeable membrane.
How does the size of molecules affect diffusion?
The larger the molecule, the slower the rate of the osmosis; and the smaller the molecule, the slower the rate of osmosis.
When salts are dissolved?
When they have a polar molecule.
What kind of molecule in the cell membrane brings particles into the cell?
Water, or H20 allows for transfer of nutrients inside the cell. The cell membrane is semi-permeable, meaning some things can penetrate it, but some things can't.
How many times does an oxygen molecule cross a plasma membrane when moving from inside an alveolus to the hemoglobin of a red blood cell and what are the plasma membranes?
1. Into the cell of the alveolus 2.+3. Out of the alvealus into cell of the capillary wall 4. Out of the cell of the capillary wall and into blood plasma 5. Into the red blood cell. So 5.

Which property of water results in a meniscus?
Adhesion due to the polarity of the water molecule.
What molecule does cell membrane contain?
The cell membrane contains phospholipids.
Which molecule of a membrane describes whether molecules can cross the membrane?
permeability
What feature of a membrane describes whether molecule can cross the membrane?
permeabiity
How does a cell move a molecule that is too large transport proteins?
The cell membrane folds around the molecule.
How are the dissolved particles of a molecular solid such as sugar different from the dissolved particles of an ionic solid such as table salt?
The components of ionic solids are held together by ionic bonds and when dissolved in a polar solvent (like water) they will dissociate into ions. For example, salt (NaCl) dissolves into Na+ and Cl-. A molecular solid like sugar, however, is held together by stronger covalent bonds and will remain the in the solvent as a whole molecule.
