Which observation about the Rocky Mountains and the Appalachian Mountains would support the claim that exposure to weathering and erosion over time can change land forms? The Appalachian Mountains are found in the eastern United States and the Rocky Mountains are found near the west coast.

The shorter and more rounded Appalachian Mountains are more than four times older than the taller and more jagged Rocky Mountains.

The length of the Appalachian chain is approximately 2,400 kilometers, and the Rocky Mountain chain is about twice as long.

The Appalachian Mountains are composed mostly of sedimentary rocks while the Rocky Mountains also contain other rock types.

You have a solution that contains phospholipid vesicles in a test tube. these vesicles have phospholipid bilayers, but do not contain any membrane transporters. you add a number of different molecules to the solution, and wait a period of time for them to equilibrate. if you could measure the concentration of each molecule, for which of the following would you expect to measure equal concentrations inside and outside of the vesicles? assume for this question that the overall osmolarity inside and outside the vesicles is the same (that is, there is no appreciable diffusion of water across the membrane). (select two answers) an amino acid with a hydrophobic side-chain a small non-polar molecule a negatively charged ion a small polar molecule a small lipid hormone
