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

How are proteins and nucleic acids related? they both provide energy. they both carry genetic information. the structure of proteins is determined by nucleic acids. the subunits of nucleic acids are also the subunits of proteins.

Astudent completed a lab report. which correctly describes the difference between the “question” and “hypothesis” sections of her report? “question” states what she is asking, and “hypothesis” states the result of her experiment. “question” states what she is asking, and “hypothesis” states what she thinks the answer to that question is in “if . . then . . because” format. “question” describes what she is trying to find out, and "hypothesis" states the procedures and methods of data collection. “question” describes what she is trying to find out, and “hypothesis” states any additional information or prior knowledge about the question.
