The answer (Image 1) is attached. Since the options weren't provided, I've attached the image of the options, too.
Explanation:
The plasma membrane is composed of phospholipids, a special form of lipids with a hydrophilic head and hydrophobic tail. According to the fluid mosaic model, the hydrophilic heads are positioned towards the outside where they freely interact with the extracellular matrix and cytosol. Whereas, the hydrophobic tails are positioned towards the inside so they aren't exposed to water.
Liposomes are lipid bases particles used for drug and vector delivery. The picture shows a typical liposome.
In the current case, for water to move both outside and inside, hydrophilic heads should be present inside as well as outside the tails.
Answer: Different liquids will evaporate differently depending on the force of attraction between the molecules of the liquid. The weaker the force of attraction the higher the rate of evaporation and vice versa.
In Sea water the water molecules are attracted to the salt ions and thus it requires more energy to evaporate.
Hi! :)
The amount of uranium within nuclear fuel rods is enough to sustain a chain reaction but is less than the critical mass necessary for the reaction to become explosive.

Explanation:
Density, the weight of an object divided by its volume, is a property of all matter, including solids, liquids and gases. The value of an object's density depends on what it's made of as well as its temperature; for example, lead weights are denser than feathers, and cold air is denser than hot air.
