21. Some authors prefer the term monosymmetry or bilateral symmetry . 22. Triploblastic organisms generally possess bilateral symmetry , which is where the clade Bilateria takes its name. 23. Unlike the other nerves supplying the larynx, the right and left RLNs lack bilateral symmetry . 24. Fluctuating Asymmetry ( FA ) is the deviation from perfect bilateral symmetry in an organism. 25. The energy required for bilateral symmetry development is extremely high, making perfect bilateral symmetry rare. 26. A sympetalous flower, with bilateral symmetry with an upper and lower lip, is "'bilabiate " '. 27. The Pyramid's construction between 200 and 250 AD completed the bilateral symmetry of the temple complex. 28. Lovecraft described the Elder Things as vegetable-like or echinoderm-like in shape, having bilateral symmetry of bipeds. 29. They developed from other members of the Bilateria and exhibit bilateral symmetry in their larval stage. 30. Bilateral symmetry is apparent from the "'heart "'stage; provascular cells will also differentiate at this stage.
