The image shows a lipid bilayer, with the polar heads represented by circles and the hydrophobic tails represented by lines. Add the fatty acids into the lipid bilayer to indicate a structure that, when incorporated into a phospholipid, would result in a more fluid membrane with a lower melting point. Be sure to insert the fatty acids into the bilayer in the correct orientation.

In november 1987, a massive iceberg broke loose from the antartic ice mass and floated free in the ocean. the chunk of ice was estimated to be 98 mi long, 25 mi wide, and 750 ft thick. a typical backyard swimming pool contains about 24,000 gallons of water. how many of these pools could you fill from the water in this iceberg? (assume the iceberg is a rectangular solid of the above dimensions and consists of water only). express answer in scientific notation.
