You are given four test tubes containing purified biological macromolecules. the test tubes are unlabeled except for a number between 1 and 4. you are told that one test tube contains a protein, one contains a lipid, one contains a carbohydrate, and one contains a nucleic acid. you then perform some tests on the macromolecules and collect the following information:
a. test tubes 2 and 4 contain nitrogen, but the other tubes do not.
b. the contents of test tube 3 are not soluble in water, but the contents of the other test tubes are soluble in water.
c. the contents of test tube 1 can be broken down into subunits that are all exactly identical to each other.
d. the macromolecule in test tube 2 is found to have a globular shape. what are the identities of the macromolecules present in the four test tubes?

1. label high-pressure areas with the letter h. 2. label low-pressure areas with the letter l. 3. over which area(s) would you expect to see rain or snow? 4. over which area(s) would you expect to see clear skies? 5. draw arrows around the h on the map to show the wind direction. 6. draw arrows around the l on the map to show the wind direction. 7. imagine that you live in maine. currently there is a high-pressure area over maine. if a low-pressure area moves in, how will the direction of the wind change? 5. draw arrows around the h on the map to show the wind direction. 6. draw arrows around the l on the map to show the wind direction. 7. imagine that you live in maine. currently there is a high-pressure area over maine. if a low-pressure area moves in, how will the direction of the wind change? 8. imagine that you live in colorado. currently there is a low-pressure area over colorado. if a high-pressure area moves in, how will the direction of the wind change? 9. according to the map, where would the strongest winds be expected? (refer to the lesson if needed.)

1. watermelon, papaya, oranges, bananas, and lemons are included in this food group. vitamin c 2. you need 6 or more servings of this food group each day vitamins d and a 3. found in fruit and keeps blood vessels healthy calcium 4. vitamins found in milk bread and grain 5. a mineral that strengthens bones fruit
