Which of these best matches a source of information with its most reliable use?

root structures → comparison of the evolution of land animals

root structures → comparison of the evolution of plant eating organisms

fossil records → comparison of the evolution of frogs and birds

fossil records → comparison of the evolution of completely soft-bodied organisms

fossil records → comparison of the evolution of frogs and birds

Fossils are the traces or remains of the dead animals or plants previously existed on earth. These are formed when the organisms dies, the soft body parts are decayed and decomposed by the microbes present in the soil. The hard remains like skeleton, shells, bones, wood, plant stems are left. These remains are covered with the piles of sediments. The sediments compacts and forms sedimentary rocks. Therefore, fossils remains preserved in the sedimentary rocks.

Fossil records are the cluster of fossils which have been identified by humans on the basis of the characteristics present in them. These records can be used to determine the evolution of frogs and birds from primitive organisms.

there is not 1 highest source of protein, but there are many; meats, fish, poultry, seafood, cheese, eggs, yogurt and milk. the only non complete animal food that is beneficial is gelatin.

sorry if this did not , have a great day!
