Their bodies taper to points at both the snout and the tail, reducing water resistance. Also decreasing drag -- and therefore noise -- are dermal denticles, sharp scales that cover the skin of most shark species. Rather than bone, sharks have cartilage, which is much lighter and more flexible. In addition, their livers produce squalene, a fatty oil that helps them remain afloat. Their pectoral fins allow them to quickly change direction, dive and swim upward.

Is a fallacy that consists of a false appeal to the authority of "everyone"; based on the assumption that a course of action should be taken or an idea should be supported because "everyone" is doing it or believes it.
If a cell’s nucleus has 55% adenine bases it also has 55% thymine bases, so the percentage of cytosine bases is 45% as same as guanine bases.
This is known as Chargaff's rule which states that DNA should have a 1:1 ratio of pyrimidine and purine bases (the amount of guanine should be equal to cytosine and the same thing with adenine and thymine).
DNA molecule globally has percentage base pair equality: %A = %T and %G = %C.
Well everyone's needs for love and attention are different. It can depend on how you were raised, if you received a lot of attention as a kid, etc. Humans are social creatures so we already crave human interaction. and, going back to how you were raised, even if you were raised quite well and you got enough attention as a kid, it really depends on how people treated you and maybe how many times you've had your heart broken or something along those lines. That need honestly varies from person to person. But I know how it feels, you'll get through it, you'll be okay.
