The answer would be too much exposure to the sun...
An excessive amount of sunlight can damage the skin. If you’ll notice, Even the effects of sunburn cause a wrinkly look to the skin.
5. Adenine and thymine base pair
6. Chargaff's base ratios
10. Hydrogen bonds exist between base pairs (A/T and G/C) allowing DNA to maintain the helical structure. Adenines and thymines have two hydrogen bonds, guanines and cytosines have three. When these hydrogen bonds are broken, this allows for "unzipping" of the DNA - which can then be replicated, transcribed/translated to RNA, etc.
C.) Here, only "Flatworm" has bilateral symmetry
