Which of the following accurately describes the structure of dna? a. a always pairs with c, and g always pairs with t. b. dna consists of four bases: a, g, c, and u. c. dna is made up of nucleotides, containing a 3-carbon sugar, a phosphate group, and base. d. dna is in the form of antiparallel strands twisted as a double helix.

Among the choices given, the one that accurately describes the structure of DNA is D. DNA is in the form of anti-parallel strands twisted as a double helix. Moreover, DNA is primarily made up of nucleotides which consists of a nitrogenous base, at least one phosphate group, and a five-carbon sugar. It should also be noted that purine adenine (A) only pairs with pyrimidine thymine (T) and the purine guanine (G) with pyrimidine cytosine (C). 

Volcanoes make new rocks so not ahotspots are the the stuff that makes volcanoes mid atlantic ridge(mar cause i’m lazy) is a constructive plate boundary so it makes sense that new rocks would be found near it, also the mar is in the middle of the ocean so it fits the description deep ocean trench, umm, there’s no ocean trenches to where you’re goingso the mar is most likely the answeri wouldn’t trust me but hey why not

Bunicellular.dinoflagellates are unicellular or multicellular, producers, and autotrophs, and apple trees are multicellular, producers, and autotrophs. all plants have numerous cells in them, so they can never be unicellular. the remaining characteristics they share with less complex organisms such as dinoflagellates.
