Textbook Readings Chapter _ 32 Animal Diversity Animals are multicellular, heterotrophic eukaryotes with tissues that develop from embryonic layers Animals are a diverse monophyletic group with 34 major animal phyla About 1.3 million species of animals living Three characteristics define the entire group 1. Mode of nutrition 2. Cell structure and specialization 3. Reproduction and development Nutritional Monde Animals are heterotrophs They cannot construct all their own or...

The Process of gut rotation Questions And Answers 1. What is gastrulation? - CORRECT ANSWER-The stage following the blastula whereby the embryo develops three layers: ecto-, meso-, and endoderm. 2. What is the etymology of the word "gastrula"? - CORRECT ANSWER-It is a modern Latin word comprised of the Greek Gaster (stomach) plus the Latin diminutive ending -ula. 3. When does gastrulation take place in humans? - CORRECT ANSWER-At the 3rd week of development. 4. What is the innervatio...

TAMU BIOLOGY 112 EXAM 3 QUESTIONS AND ANSWERS ALREADY PASSED Select the TRUE statement about animal development: A.) Deuterostome development is indeterminate. B.) Mesoderm in protostomes arises as outpocketings of the primitive gut. C.) Radial cleavage is characteristic of protostome development. D) In deuterostomes, the blastopore ultimately becomes the mouth of the adult. E) All of the above are true. Deuterostome development is indeterminate. During embryogenesis o...
