An analysis of a lipid shows that it is made up of two fatty acids and a phosphate group, each bonded to a glycerol molecule. The molecule has a hydrophobic end and a hydrophilic end. Based on this information, what conclusion can you draw regarding this lipid?
A.The lipid is a fat and can be used as an energy reserve.
B. The lipid is a phospholipid and can form a bilayer in a cell.
C.The lipid is a chitin and can be found in the exoskeletons of arthropods.
D. The lipid is a steroid and can arrange itself to form ring structures

DO YOU KNOW THIS ONE 

Some antibiotics can harm the ribosomes in animal cells. Which of the following would you predict to be the most likely long-term effect of damage to ribosomes?
 Substances would not be able to enter or leave the cell, and affected cells would eventually burst. 

 Proteins would not be modified after being synthesized, and would be unable to function properly. 

 Cells would die because they would not be able to create the proteins needed to carry out life functions. 

 Errors would be made during DNA replication, and cells would then be unable to grow and divide.
