Answer:
t describes Linus Pauling's contribution to the understanding of DNA structure?
Having first discovered the spiral shape of proteins, Linus Pauling used x-ray technology to hypothesize that the DNA molecule consisted of two consistently spaced strands that formed a spiral shape.
Linus Pauling studied DNA base pairing.
Having originally studied proteins, Pauling proposed that DNA was a three-chained helix with a sugar-phosphate backbone at the center and bases sticking out from the backbone.
Linus Pauling conducted experiments to prove that DNA carried genetic information.
Explanation:
Chickens do not need teeth. It is a muscular part of the stomach and uses grit small, hard particles of pebbles or sand to grind grains and fiber into smaller, more digestible, particles. From the gizzard, food passes into the small intestine
The controlled variable is what stays the same . So it’s C . They are given different amounts but the same food.
