A phospholipid bilayer. Lipid molecules are arranged so that their heads point outward and their tails point to the center of the membrane. Embedded in the phospholipid bilayer are the following structures. A: A long branched chain of molecules attached to a lipid in the membrane. B: A large structure that spans the entire membrane with a hollow channel in the middle. C: A long branched chain of molecules attached to a protein. D: A protein with a long branched chain of molecules attached to it.

the sugar-phosphate backbone forms the structural framework of nucleic acids, including dna and rna. this backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.

the main thing i would use is bricks because if there is a hurricane, there is a great possibility for the house to still stand. and i would also use plexiglass windows instead of regular windows because plexiglass isn't prone to breaking.
