Answer: Scientist can determine if an object should be classified as living or non-living cells by looking under a microscope with a slide. If the slide has cells in it, it is considered alive and if the cells contain food, water, exposed waste, and environment, it is alive. If the object or slide does not have any cells in it, it is considered non-living because for a cell to be alive, it needs cells in it.</h3>
<span>b The growth of teeth in chickens supports the hypothesis of a common ancestor between birds and reptiles. This is a generally accepted hypothesis, and i'd go with this answer. Obviously we can't say whether chickens will have teeth with certainty, the chickens with teeth are clearly still chickens, and a baby croc isn't hatching out of a chicken egg any time soon.
