In order for a triacylglycerol molecule to form, which of the following must be true? a. Sphingosine must be present to link the fatty acid together. b. Water molecules must be added to form the bonds. C. Three identical fatty acids must be present. d.A dehydration synthesis reaction must occur. e.Hydrogen bonds hold the components together.

In a lab, silver nitrate, AgNO3, is dissolved in water until no solid is observed in the container. Then, a solution of sodium chloride, NaCl, is added to the container. When you combine these aqueous solutions, there is no noticeable change in temperature; however, a solid precipitates and there is a slight change of color. Which statements about the lab experiment involving silver nitrate and a sodium chloride solution are true? Drag each item to the appropriate bin. ► View Available Hint(s) Formation of a solid indicates a chemical reaction occurred. The initial disappearance of silver nitrate in water indicates a chemical reaction occurred. The lack of temperature change indicates a chemical reaction didn't occur. True Reset hemical reaction occurred when silver nitrate was added to water. The color change of the solution indicates a chemical reaction occurred. A chemical reaction did occur when the solutions were combined. False Help

9. What do glycerophospholipids and sphingomyelin have in common? a. They contain two fatty acids. b.They have components that are linked together by the molecule glycerol. c. They are the most common molecule in cell membranes. d.They contain a phosphate group attached to an amino alcohol. e.They have a common basic structure with four fused rings.

Choose the correct condensed structure from the name: hexene. OCH3CH₂CH₂CH₂CH₂CH3 CHCCH₂CH3 CH3CH₂CHCHCH₂CH3 CH3CHCHCH₂CH3

Why does the temperature remain constant during a phase change? The heat added during a phase change is used to disrupt the attractive forces between molecules and to increase the motion of the molecules. The heat added during a phase change is only used to disrupt the attractive forces between molecules. The heat added during a phase change is only used to increase the motion of molecules. The heat added during a phase change is only used to increase the vibration of molecules
