According to the endosymbiotic theory, which of the following is NOT true about the evolution of life on earth? Eukaryotes and prokaryotes appeared at about the same time and evolved independently from each other. O None of the other four answers (all are true statements) Eukaryotes evolved from symbiotic prokaryotes living inside other prokaryotes Mitochondria and chloroplasts are in some ways similar to prokaryotes The first life on earth was simple organisms, similar to today's prokaryotes
Which of the following illustrates the unity observed in organisms with a common ancestor? Flamingos and penguins are different colors. The gene for the human hormone insulin can be inserted into bacteria, and the resulting bacteria can use the gene to produce functional insulin. A robin can fly, but a penguin cannot. Fungi tend to absorb nutrients from other organisms, while animals consume their food. O Living organisms span a range of sizes.

ana transiaTion vary wkery. One of the prerequisites for chemical evolution on early Earth is that there was an adequate amount of time. This is an important assumption because there had to be enough time for which of the following to occur? * RNA needed to start catalyzing reactions. The sun needed to begin to produce infrared radiation. Molecules needed to form, react, and reform. Oxygen needed to leave the atmosphere. Deer mice are usually found in the woods and are dark brown in color. The deer mice that live in the Sand Hills of Nebraska, however, have evolved a lighter coloring, the result of a change in one gene. A scientist decides to move a population of brown deer mice to a habitat composed of a mixture of sandy areas and dark rocks. After monitoring the population for several generation, she finds that it is composed of a mixture of very light and very dark colored mice. What type of selection has occurred?*

What characteristic distinguishes nucleic acids from proteins making them better candidates to have been the hereditary molecule in the first protocells? A single molecule contains the information needed to make a duplicate copy. They are complex enough to carry instructions to build a cell. They have catalytic activity. They can compartmentalize. Their monomers form abiotically.
