Exploring Creation with Biology - Study Guide for Module #16 – Reptiles, Birds, and Mammals
1. Write out the definitions for the following terms; memorize for the test: a. Amniotic egg – An egg in which the embryo is protected by a membrane called an amnion. In addition, the egg is covered in a hard or leathery covering. b. Neurotoxin- A poison that attacks the nervous system, causing blindness, paralysis, or suffocation. c. Hemotoxin – A poison that attacks the red blood cells and blood vessels, destroying circulation. d. Endothermic – A creature is endothermic if it has an internal mechanism by which it can regulate its own body temperature, keeping it constant. e. Down feathers – Feathers with smooth barbules, but no hooked barbules. f. Contour feathers – Feathers with hooked and smooth barbules, allowing the barbules to interlock. g. Placenta – A structure that allows nutrients and gases to pass between the mother and the embryo. h. Gestation- The period of time during which an embryo develops before being born, i. Mammary glands – Specialized organs in mammals that produce milk to nourish the young. 2. State the five characteristics that set reptiles apart from other vertebrates? They are covered with tough, dry scales. They breathe with lungs. They have a three-chambered heart with a ventricle which is partially divided. They produce amniotic eggs covered with a leathery shell. Most are oviparous, some are ovoviviparous. If they have legs, the legs are paired. 3. In this module, we studied reptiles, birds, and mammals. For each class, indicate whether they are ectothermic or endothermic. Reptiles are ectothermic, while birds and mammals are endothermic. 4. Identify the parts of the amniotic egg:
5. State the function of the yolk, the allantois, and the egg white. The yolk provides nourishment to the embryo, the allantois lets the embryo breathe, and the egg white protects the embryo from pathogens. 6. What do arthropods and reptiles...
