Hydrophilic
A phospholipid is comprised of a phosphate hydrophilic head, which means that it is "water-loving," and a fatty acid hydrophobic tail, which is "water-hating." The head and the tail are joined together by a glycerol molecule.
The phosphate head is attracted to water because it is charged (i.e. negatively). Water is a polar molecule, which means that there is an uneven distribution of charges within its molecular structure with the oxygen side being "more negative" than the rest of the atom (which is "more positive" near the hydrogen). Thus, the negatively-charged nature of the phosphate head and the parts of the water molecule which are positively charged enable the two to form an "attraction" towards one another.
On the other hand, the hydrophobic tail is nonpolar, which means that it does not have a "more positive" or "more negative" side or part in its molecular structure. These differences in structure with water make the hydrophobic tail unattracted to water molecules and more attracted to other uncharged, nonpolar molecules (such as fats and oils).

Answer:
2
Explanation:
X2-8 = -1
X2= -1 +8
X2= 7 (so, if you add 2, it will 9 square of 3)
Answer: The second factor that leads to fluidity is the nature of the phospholipids themselves. In their saturated form, the fatty acids in phospholipid tails are saturated with bound hydrogen atoms; there are no double bonds between adjacent carbon atoms. This results in tails that are relatively straight
An estuary is a place where seawater and freshwater mix.
Your tap water is treated water from which organisms and excess ions have been removed.
That rain-washed all sorts of particles and chemicals into the ocean.
After a few million years, it evened out and the amount of things coming into the ocean equaled the amount leaving.
It's a term called equilibrium.
