The diagram below represents one possible evolutionary change that could have led lobe-finned fish to develop into the first amphibians. Amphibians are animals that live on land some of their life.

This change from fins on the lobe-finned fish to legs and feet on the early amphibian is most likely due to

Group of answer choices

1.the need to move to land because of increased competition for food in the ocean

2.increased competition between animals that had adapted to living on the land

3.a sudden mutation that changed the gills of the lobe-finned fish to lungs

4.variations among offspring, followed by natural selection

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
