Atie wants to make ball-and-stick models of the four macromolecules. She has colored balls for each of the elements in these molecules, including the following. red: hydrogen black: carbon purple: oxygen green: nitrogen In the macromolecule of the carbohydrates she will use the black, red, and purple balls in a ratio of 1:2:1. The carbohydrate molecules are glucose (ratio of 6:12:6) and fructose (ratio of 6:12:6).

1. loamy sand is about 80% sand with 10% clay and defined mostly by sand particles with some clay to provide structure and fertility. the sand particles are easily visible and the soil holds structure but breaks apart easily.
