When phospholipids are mixed with water their interact with water and their are repelled, forming a lipid bilayer. hydrophilic heads; hydrophobic tails hydrophobic tails; hydrophilic heads hydrophobic heads; hydrophilic tails hydrophilic tails; hydrophobic heads?

The answer is;  hydrophilic heads; hydrophobic tails

The hydrophilic heads of a phospholipid are composed of a phosphate and glycerol molecule. Since the phosphate has a charge, the head are able to interact with water molecules through hydrogen bonds (Remember water is a polar molecule).  The hydrophobic tails are composed of hydrocarbon chains that are uncharged hence do not interact with water. When phospholipids are immersed in water, they form a bilipid layer - with the hydrophobic  tails clumped up together in the center and the hydrophilic heads on the outside.

the answer is admiramos

the rule for verbs is whoever you are referring to (in this case 'nosotros'), you need to change the ending of the word.

nosotros - amos

yo - o

tu - as

el, ella, usted - a

ellos, ellas, ustedes - an

(examples: nosotros bailamos (instead of bailar) or yo hablo (instead of habla)
