Answer:
the double helix of dna is, like its name, implies, in the shape of a helix which is essentially a three-dimensional spiral. the double comes from the fact that the helix is made of two long strands of dna that are intertwined—sort of like a twisted ladder.

hope this helps :)
have a nice day !!
They all don’t, they also can have positive charges like LiOH (Lithium Hydroxide)
Answer:
VH2SO4 = 145.3 mL
Explanation:
Mw BaO2 = 169.33 g/mol
⇒ mol BaO2 = 53.5g * ( mol BaO2 / 169.33 g BaO2) = 0.545 mol BaO2
⇒according to the reaction:
mol BaO2 = mol H2SO4 = 0.545 mol
⇒ V H2SO4 = 0.545 mol H2SO4 * ( L H2SO4 / 3.75 mol H2SO4 )
⇒V H2SO4 = 0.1453 L (145.3 mL)
Waves with higher frequencies have shorter wavelengths, and lower frequencies have longer wavelengths
