Perform a chi-square test of independence on the data provided in Figure 7.2 to determine if the genes for flower color and pollen shape in sweet peas are assorting independently. Give the chi-square value, degrees of freedom and associated probability. What conclusion would you make about the independent assortment of these genes?

Atoms used energy to make new molecules.

Explanation:

Atoms used energy to make new molecules through making bonds with one another because bonds allow atoms to attached tightly with each other. The energy come from the external environment in order to produce new molecules. So we can conclude that energy is the main ingredient needed for making new molecules and this energy is gained from the environment.
