Why do phospholipids form a bilayer in water?

The hydrophobic tails aggregate to form a bi layer.

Explanation:

Phospholipids are major constituents of the plasma membrane. These are triglycerides having lipid part and phosphate part. The phosphate portion is the water-loving/hydrophilic and the glycerol tail or lipid part is water hating/hydrophobic. Hence, it is an amphipathic molecule. The hydrophobic tail aggregate with each other to form a lipid bilayer in the water.  Therefore, the lipid tails prevent water molecules to enter the bilayer.

the dna of humans and mice is almost 92% similar. this similarity indicates that . mice have a tail, while humans have a tailbone. the tailbone is a structure in humans.yes it's true.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
