Answer:
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.
Energy in organisms is called ATP (specifically energy in the cell). I hope I helped!
This pedigree doesn't show an autosomal dominant trait because 3,4 are carriers, passing the gene to their offsprings but don't manifest the phenotype. This pedigree can represent an autosomal recessive gene based on what I just mentioned. We know that this is an autosomal trait because it seems to affect both genders equally.
