Each shape in the chart represents a different type of atom. Atoms with a line (stick) between them show a chemical bond. Cells A through D tell you whether or not a chemical bond occurs when the atoms combine.
Use the drawing tool to fill in cells A through D in the chart. Show what will happen when the atoms or molecules combine. Use stick models as necessary.
Part B
Which combinations form compounds? How do you know?

Which combination is an element? How do you know?

Did any mixtures form? Why or why not?

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
