Which process contributes to the formation of layers in protoplanets when unstable elements release particles and energy? compaction evaporation radioactive decay collision of space materials

Radioactive decay

Explanation:

Radioactive decay refers to the natural breakdown of unstable elements or nucleus which lead to the release of energy or particles like alpha particles or beta particles.

It result in the formation of layers in protoplanets.

The four different types of radioactive decay are,

Alpha particles

Beta particles

Gamma decay

Positron emissions.

prokaryotic cells do not have a nucleus in which the dna is stored in, it floats freely inside the cell.

eukaryote cells do have a nucleus in which the dna is stored in.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
