A punnet square determines all of the ways in which alleles can combine. It may be used to predict ratios of offspring genotypes and phenotypes. However, Punnet squares cannot determine actual outcomes. They can only predict the possibility for things to happen. The exception to this takes place when the cross occurs with two homozygous dominant or recessive genes and the resulting offspring is either be 100% homozygous dominant or recessive.

Phosphorus cycle is a biogeochemical cycle that observes how phosphorus move through minerals, soil, water, and organisms. Typically, plants absorb phosphorus from the soil. And animals get phosphorus from the eaten plants. When these organisms dies, they decay and the phosphorus returns to the soil and inorganic matter.
