Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature. Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.arrow_forwardUse the following tree diagram to answer Questions #8-10. 8) Which of the following two animals are the most closely related based on the tree to the left? a) Pig and camel b) Hippo and pig c) Deer and cow 9) CIRCLE on the tree diagram where the common ancestor between a hippo and a cow is. 10) Put a SQUARE on the tree diagram where the common ancestor between a pig and a peccary is.arrow_forward
