If the shape of this unknown skull is long and skinny at the cheekbones, then it is most likely an Australopithecus afarensis one
Answer:
The reason for qualifying 'in vacuum' is because EM waves of different frequencies often propagate at different speeds through material.
Explanation:
Electromagnetic waves include visible light, radio waves, X-rays, and so on. What distinguishes these different bands of light is their frequency (or wavelength). But what they all have in common is that they travel at the same speed in vacuum.
The reason for qualifying 'in vacuum' is because EM waves of different frequencies often propagate at different speeds through material.
The speed of a wave c, its wavelength λ and frequency f are all related according to c=λf. So if c is the same for all EM waves, then if you (say) double the frequency of a wave, its wavelength will halve.

A phospholipid is the macromolecule that forms the phospolipid bilayer of the cell membrane. A phospholipid is contained of two fatty acids. They form a bilayer that is hydrophobic on one side and hydrophillic on the other.
