Answer:
Each one has two fatty acid chains and the glycerol backbone is bonded to a small polar group.
Explanation:
Phospholipid is a unique form of lipid. The bonding of the glycerol backbone to the polar phosphate group makes phospholipid to have dual solubility unlike general triglycerides.
The polar head is said to be hydrophillic that is <u>water loving,</u> while the two carbon chains that retained lipid features are hydrophobic <u>water hating.</u>
Therefore if a phopholipid is placed in water, in relation to its functions as component of cell membrane, it forms a bi-layer in which the water loving portion hydrophilic head points into the surrounding watery medium, while the hydrophobic layer points inwards far away from the watery medium into the internal cellular layer to form an impermeable barrier to hydrophilic (polar) substances.
This forms the basis of the phospholipd bilayer of the cell membrane. And it controls the permeability of the cell membrane to influx substances into the cells.

Answer:
The answer is the 2nd picture: the coccyx bone in humans.
Explanation:
Vestigial Structure:
Structures or anatomical features that do not currently serve a function is the bodily processes of a living organism. Vestiges are believed to have performed active functions in the organism's ancestors throughout its evolutionary history.
Coccyx Bone:
The coccyx or tailbone is an evolutionary remnant of our tree dwelling ancestors. Coccyx has no use in modern humans as we do not need to climb trees.
The coccyx in modern humans serves as an anchor for muscles.
It is about 78%, I hope that this helped :)
