FOCUS ON EVOLUTION
The human esophagus and trachea share a passage leading from the mouth and nasal passages, which can cause problems. After reviewing vertebrate evolution (see Concept 21.4), explain how descent with modification explains this “imperfect” anatomy.

- Jay Guide The human embryo and the embryos of other animals with backbones have gill slits. According to the modern evolutionary theory, this best supports the idea: Mark only one oval.

Embryos go through various stages that suggest the animal’s evolutionary process. Embryos are frequently fossilized and illustrate change over time. Embryos provide evidence for which life forms existed at the same time. Embryos contain the code for all life on Earth.arrow_forward

- Regents Practice: Base your answer to question 1 on the information below. Ten years ago, scientists discovered a well-preserved set of dinosaur remains in China. This dinosaur, which walked on Earth about 125 million years ago, had feathers and was about the same size as a turkey - but don't be fooled. This dino's bite was a lot worse than a turkey's gobble. After a close (and careful!) examination of the dino's teeth, scientists recently concluded that this dinosaur was probably poisonous. The study was led by David Burnham, who works and teaches at the University of Kansas in Lawrence. Source: www.sciencenewsforkids.org 1. State one inference that could be made based on the fact that this dinosaur had feathers. 2. Extension Activity: Evaluate the different types of evidence supporting evolutionary relationships between species. Which type of evidence do you think provides the most support for evolution today? Justify your response. Evidence:arrow_forwardGive at least 10 exoskeletons found in animals, source, its description and state their embryonic origin. (Explain in 1-3 sentences) (Use the table)arrow_forwardat a large Assume that you are the nurse elementary school where children frequently come to you with nosebleeds. Design an experiment to test whether dropping keys down the back of the neck causes nosebleeds to stop. (Assume parents of all children in the school have given permission for their participation in the experiment and you have followed ethical guidelines for research with human subjects. One possible explanation for why keys down the back might actually be effective in stopping a nosebleed is that they are cold, causing blood vessels to constrict. Treatments should be randomly assigned to the children. Describe how you accomplish this. That is, when a child with a nosebleed comes to the nurse's office, how will you know which treatment he or she should get?arrow_forward
