Question

what do these two changes have in common? baking cookies cellular respiration select all that apply. both are caused by cooling. both are caused by heating. both conserve mass. both are chemical changes.

Explanation:

Baking cookies involves chemical reactions due to heat - induced changes in ingredients like flour, sugar, and eggs. Cellular respiration is a series of chemical reactions in cells that convert glucose and oxygen into energy, carbon - dioxide, and water. According to the law of conservation of mass, mass is conserved in both chemical processes. Neither is caused by cooling, and baking is due to heating while cellular respiration occurs at body temperature without external heating in the same sense as baking.

Answer:

C. Both conserve mass.
D. Both are chemical changes.
