What characteristic of life is demonstrated here? Group of answer choices   irritability cellular nature natural selection development evolutio

You are studying the evolution of species. After performing DNA analysis, he discovers a gene that is conserved from yeast to humans. In which cellular processes is this gene most like to be involved? Could this gene have evolved to confer some of the complex traits that we observe in modern animals, like multicellularity? Briefly explain.

Many crustaceans (for example, lobsters, shrimps, and crayfish) use their tails to swim, but crabs have reduced tails that curl under their shells and are not used in swimming. This condition is an example of what evidence of evolution? *       Homologous structure Convergent evolution No answer Vestigial trait Natural selection
