For the following reaction, use the identity of the alkyl halide and nucleophile to determine which substitution mechanism occurs. Then deteremine which solvent affords the faster reaction. Reaction: Cl structure + CH3OH > (above arrow is H2O and below is DMSO) OCH3 structure + HCl.

Draw the skeletal structures of two different molecules that are each made of 5 carbon atoms and 12 hydrogen atoms.

If the concentration of phosphate in the cytosol is 2.0 mm and the concentration of phosphate in the surrounding fluid is 0.1 mm, how could the cell increase the concentration of phosphate in the cytosol? a) passive transportb) diffusionc) active transportd) osmosise) facilitated diffusion

Why does earth rotate? because earth is formed from cold gases collapsing due to gravity because the matter in the nebula that formed earth was spinning because earth forms more than 99% of the mass of the solar system because the hydrogen atoms inside the nebula fused to form helium
