Plss ! the models below represent nuclear reactions. the atoms on the left of the equal sign are present before the reaction, and the atoms on the right of the equal sign are produced after the reaction. model 1: atom 1 + atom 2 = atom 3 + energy model 2: atom 4 = atom 5 + atom 6 + energy which of these statements is most likely correct about the two models?

a. both models show reactions which produce energy in the sun.

b. both models show reactions which use up energy in the sun.

c. model 1 shows reactions in the nuclear power plants and model 2 shows reactions in the sun.

d. model 1 shows reactions in the sun and model 2 shows reactions in a nuclear power plant.

Nerve cells are specialized to respond to stimulitrue or false?

Why is the theory of evolution important? it disproves all other theories about how life began. it provides a topic for debate. it is a unifying concept in biology. it explains how life began. i know for sure, it is not "it is a unifying concept in biology."

The graph below compares the rates of reaction of a burning candle and an exploding firework. comparing chemical reactions what can you conclude from the graph? the reaction that causes a firework to explode requires less energy to start, and occurs more rapidly than the reaction that causes a candle to burn. the reaction that causes a firework to explode requires less energy to start, and occurs less rapidly than the reaction that causes a candle to burn. the reaction that causes a firework to explode requires more energy to start, and occurs less rapidly than the reaction that causes a candle to burn. the reaction that causes a firework to explode requires more energy to start, and occurs more rapidly than the reaction that causes a candle to burn. mark this and return
