C) break down to form atoms of another element.

Explanation:

The process of radioactive decay, synonymous for half-life (t1 / 2) or half-disintegration period (P), is the statistical phenomenon that allows us to predict how long a given number of atoms will produce radioactive emissions. This statistical forecast assumes the transmutation (decay synonym) of 50% of radioactive atoms in a given period of time. Since the process is continuous, there is a radioactive decay curve that tends infinitely to zero.

[ answer ]

foliated

[ explanation ]

foliation forms in a rock when pressure squeezes the rock together. the rock then has a design of many different color little lines. there are three types of foliated rock. the types are slate, schist, and gneiss. each type of foliated rock is different based on grain size and foliation characteristics. the lines appear when the rock has been under pressure.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
