Natural abundances vary based on the planet and its formation history. For example, Mars and Earth have different oxygen isotope ratios. It has been suggested that the moon was formed when a planet-sized object struck a glancing blow on Earth. Although the cores remained largely intact, the remnants of these two bodies eventually reformed into Earth and moon. Explain how you could use isotopic analysis to support this theory.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.

answer: cellular respiration takes in food and uses it to create atp, a chemical which the cell uses for energy. usually, this process uses oxygen, and is called aerobic respiration. it has four stages known as glycolysis, link reaction, the krebs cycle, and the electron transport chain.
