The double-helix structure of DNA was discovered using X-ray crystallography (Rosalind Franklin) and elucidated by Watson and Crick.
Before this discovery, it was previously known that DNA is comprised of
four nucleotide bases: adenine, thymine, guanine, and cytosine. Adenine
always binds to thymine, while guanine always binds to cytosine.
You analyze a double-helix and determine that 17% of the helix is made up
of the nucleotide adenine (A). What percentage of the same helix must be
comprised of the nucleotide guanine (G)?

Because of its structure the cell membrane is known as a phospholipid ? a.bilayer b.molecule c.fluid d.barrier

Red flowered snapdragons are crossed with white flowered snapdragons, producing all pink snapdragons in the f1 generation. what would you expect if you crossed pink with pink? 3/4, 1/4, 1/2 red, 3/4,/1/2,/1/4 pink,1/2, 3/4, 1/4 white

Be in this im starting a with you so if you want you can get a partner for this. but basically im going to assign you guys a biome and you have to have a big sheet paper and you will turn it into 4 squares. the top right square is will be a drawing square for a drawing you will make of your biome. the top left square is about the biomes plants and drawings of them. the bottom left square is about the biomes animals. the bottem rights square is about the description of the biome. leave a comment or an answer and i will assign biomes. if your request one thats the one you get. send me a link to the project and i will grade ! im not a teacher btw.
