Each phospholipid is made up of 2 fatty acid molecules, a phosphate group and a molecule of glycerol.
The fatty acid molecules are formed by long chains of carbon and hydrogen.The phosphate group is formed by an atom of the element phosphors which is attached to four oxygen atoms. The fatty acids make the tail and are hydrophobic. The phosphate group makes the head.
Due to their structure, phospholipids are best suited to make the cell membrane in organisms.
Answer:
The law of conservation of mass states no matter is created or destroyed. This means that the matter currently on Earth is the only matter that will ever be available to us. However, it also means that this matter will not be destroyed. So, water, oxygen, carbon, and nitrogen are all used by living things in our world and then recycled to be used again.
One example of this is the water cycle. More water is never added or taken from the world, it is just reused. First, water starts in some body of water and then evaporates into the air. Then, the water falls back to Earth as precipitation.
