Ten points me out it's due in an hour

1A):  Fats are  >     Solid at Room temperature

1B):   Oils  are    >  Liquid at Room Temperature

2A):  Lipids > Are a group of organic compounds, that include fats, oils, waxes and related substances. Lipids are composed of carbon and hydrogen, and oxygen, but there is no definite ratio of hydrogen to oxygen atoms lipids as there is in  carbohydrates. Simple lipids, which are the most  common type, are made up of three fatty acids molecules, and glycerol molecule.

2B):  Carbohydrates  > Are organic compounds composed of carbon, and hydrogen, and oxygen. The proportion of hydrogen atoms to oxygen atoms in carbohydrates is the same as in water; Two hydrogens to one oxygen. There are three basic types of carbohydrates. Monosaccharides, disaccharides, and polysaccharides.

3): A positive control ===> should give the desired outcome of the experiment, provided that all the reagents and equipment are functioning properly. For example, if your experiment results in the ability of bacteria to grow on a petri plate containing antibiotic, your positive control will be bacteria that are known to carry the appropriate drug resistance marker. Even if none of your experimental bacteria grow, as long as there is growth of the positive control you know that growth was possible.  

3B):   A Positive Control  > should be designed to not give the desired outcome of the experiment. In the example above, bacteria which do not carry a drug resistance marker should not be able to grow on a petri plate containing antibiotic. If growth is observed, it is a red flag that something is wrong with the experiment.

Hope that helps!!!                                  : )
