Which type of membrane protein is characterized by having a unique strand of sugar molecules attached to it? receptor protein cell recognition protein channel protein carrier protein which statement correctly describes why the phospholipids of the cell membrane arrange the way they do in a bilayer? the nonpolar tails are repelled by water, so they position themselves in the middle of the bilayer. the polar heads are attracted to water, so they point outward. the polar heads are attracted to water, so they position themselves in the middle of the bilayer. the nonpolar tails are repelled by water, so they point outward. the polar heads are repelled by water, so they position themselves in the middle of the bilayer. the nonpolar tails are attracted to water, so they point outward. the nonpolar tails are attracted to water, so they position themselves in the middle of the bilayer. the polar heads are repelled by water, so they point outward. determine if the following statement is true or false. if true, choose true. if false, choose the rewording that is true. as cell size increases, the surface area-to-volume ratio increases. true as cell size decreases, the surface area-to-volume ratio increases. as cell size decreases, the volume of the cell increases. as cell size decreases, the surface area-to-volume ratio decreases. ! will give brainliest no spam answers. which characteristics correctly describe prokaryotic cells? (select all that apply.) there is more then one correct have a nucleus have membrane-bound organelles have no nucleus have no membrane-bound organelles

1. The correct answer is cell-recognition protein.  

These kinds of proteins are classified as a glycoprotein as they are the proteins with a molecule of carbohydrate associated with it. These proteins tag the cell and assist the immune system to determine them so the cells are identified and not destructed.  

2. The correct statement is the nonpolar tails are repelled by water, so they position themselves in the middle of the bilayer. The polar heads are attracted to water, so they point outward.

Water refers to a polar molecule, thus, dissolves charged molecule with which it can produce hydrogen bonds. The uncharged or nonpolar molecule seems to be water-hating and thus produces clumps when putting in water and does not get dissolved. The amphipathic molecules like phospholipids seem to produce the lipid bilayer with the polar heads from the external and getting associated with water, and the non-polar carbon chains remain sandwiched in between, that is, away from the water.  

3. As the cell increases, the surface-area-to-volume ratio increases is false, with the decrease of the cell size, the surface area to volume ratio increases will be the correct statement.  

As the cell size decreases, the volume of the cell increases is false, the correct statement is that as the cell size decreases, the volume of the cell decreases.  

As the cell size decreases, the surface-area-to-volume ratio decreases are false. The correct statement is that as the cell size decreases, the surface-area-to-volume ratio increases.  

4. The correct answers have no nucleus and have no membrane-bound organelles.  

In prokaryotes, the DNA is not enveloped by a nucleus membrane, and thus, there DNA is not separated from cytoplasm as in the case with eukaryotes. Also, they are devoid of membrane-bound organelles as they are primitive organisms.  

i believe it would cause an increase of percipitation, though i could be wrong. so i would say b is the answer.
