Textbook Question
Chapter 17, Problem 13PS
Vegan and vegetarian diets are increasingly popular. While vegans consume no animals or animal products, many vegetarians are less strict. Talk to acquaintances who describe themselves as vegetarians, or who follow a meat-free diet, and determine which taxonomic groups they avoid eating (see Figures 17.6 and 17.30). Try to generalize about their diet. What do they consider “meat”? For example, do they avoid eating vertebrates but eat some invertebrates? Do they avoid only birds and mammals? What about fish? Do they eat dairy products or eggs?

Ungulates
Ungulates, such as deer, reindeer, and elk, are hoofed mammals. These animals have keen hearing, clear vision, supple, well-conditioned muscles, and razor sharp reflexes. The evolution of the four-chambered stomach in ungulates developed as a result of a need to eat quickly in the open and chew later in the safety of cover. This process is called ruminating or "chewing the cud." In other words, ungulates regurgitate and then re- chew their food.
Which of the following would be considered a physiological adaptation of ungulates?
A) their four-chambered stomach B) their long legs, which help them outrun predators
C) their ability to stand perfectly still, which helps them avoid predators
D) their ability to hibernate to avoid cold winters
Nutrition and Digestion
Identify the different modes of feeding mechanisms found in the Animal Kingdom, describe each and give 2 example animals for each mode.
Why do Cnidarians, Flatworms and Protists have simple or no extensively developed digestive system? (clue: mention their digestive structure and their mode of feeding)
What are the structural adaptations of snakes that allowed them to eat and digest a whole prey?
Why do insects of one species have a changing diet requirement during their life history?
Different birds have varying food habits, discuss the structural and physiological adaptations that allow them to process these foods.
What are the four stages of the digestive process, describe each stage/step and indicate what are the products/substances produced and their fate?
Discuss the role of the endocrine system in controlling digestion.
(no plagiarism pls, thank u!)
Describe the main difference between the planarian and vertebrate digestive systems.
Question 13 options:
The planarian does not have digestive system.
The planarian digestive system is a branching gut sac that only has one opening to the environment.
The planarian digestive system has a body opening to the environment on both of its ends, but a vertebrate digestive system does not.
The vertebrate digestive system does not have as many highly specialized organs as that of vertebrates.

Animals that eat the most food become the most abundant. Animals that restrict their food intake will become less abundant. Animals with mutations that give rise to effective structures will become more abundant. Animals with parents that continually improve their offspring's structures will become more abundant. Animals with inventions that curtail reproduction will become more abundant.arrow_forwardConsider the following image of the teeth in the lower jaw of select primates.

- 1 Using the human digestive system as a point for comparison, determine which of the other vertebrate groups/classes are very similar and very different from a human digestive system aspect. 2 Using a table, label the 1st column as “Digestive organ”, the 2nd column “Humans”, the third column, and so on (should contain the name of the group/class that you need to compare). 3 All the digestive organs for all the groups/classes should be present in the first column labeled “Digestive organs”. 4 The rows after for the digestive organs corresponding to the respective columns/group/class should include the function of the organ respectively. 5 If the organ is not present in a particular group/class, just put “ABSENT”. 7 Based on commonalities and variations/differences, conclude in a statement which vertebrate group is the most similar and most different to a human digestive system.arrow_forwardChoose 5 filter feeders including sponges and whale sharks, each from a distinct animal phyla or class: Make a phylogenetic tree to show how they are related to one another propose how and why so many animals could have developed filter feeding & what would happen if we removed filter feeders from the oceanarrow_forwardAnimals with bilateral symmetry can be divided into similar halves by any plane through the longitudinal axis. are usually very slow-moving organisms. are relatively simple in structure. are better adapted for forward movement than radially symmetrical organisms.arrow_forward
- The presence of villi and smooth muscle increases the surface area for nutrient absorption in the gut of many animals. This statement is (T/F). • If true, enter x in the blanks below. • If false, then how would you change the sentence to make it correct? You can change two words at most. Changes that just reverse the meaning (e.g. changing "is" to "isn't" or "all" to "none") will not earn credit. I would change the word(s) to the word(s) to make the sentence correct.arrow_forwardThousands of years ago, the jaws and teeth of jaguars were more varied in size than they are today. During a period of climate change about 11,000 years ago, jaguars faced a shortage of food. There were fewer mammals to eat, so the jaguars had to eat shelled reptiles. The jaguars with the largest jaws and teeth could most easily eat the shelled reptiles. Which of the following statements best explains why large jaws and teeth are common characteristics in jaguars today? Jaguars with smallest jaws and teeth died out completely. Jaguars with the smallest jaws and teeth were not able to mate. Jaguars with the largest jaws and teeth survived and reproduced more successfully than the other jaguars. Jaguars with the largest jaws and teeth strengthened them by using them more frequently than the other jaguars.arrow_forwardWhat occurs as body size increases in animals ? there is a decrease in the surface-to-volume ratio. reproduction becomes limited to terrestrial environments. there is greater variability in metabolic rate. migration to tropical areas becomes necessary for thermoregulation. it becomes more difficult to conserve body warmth in cold environments.arrow_forward
- For this activity, you should familiarize the diverse group of vertebrates and make a phylogenetic tree showing their evolutionary relationships. This tree should be primarily based on physical characteristics, such as: I. Presence or absence of a backbone II. Ability to breathe in air or water III. Cold or warm blooded IV. Carnivore, herbivore, or omnivore V. Presence or absence of hair/fur VI. Any other external structure such as horns TO DO: Lay all the animals on their desks and separate them into two groups using the physical characteristics above☝ The animals are on the picture.arrow_forwardMorphology - Comparative Anatomy More evidence for evolution is offered by comparing the anatomy, or body parts, of different organisms. Many animals have body parts that are similar in both structure and function called homologous structures. The forelimbs of animals like humans, whales, birds, and other creatures are strikingly similar even though the forelimbs are used for different purposes such as lifting objects, swimming, or flying. The different changes in the forelimbs are adaptations to the needs of the organisms. Darwin also observed that animals have structures that they do not use, which are called vestigial organs. These are structures that an organism has that do not have a function, though they may have had one in the past. In humans they include the appendix, the fused tail vertebrae, and Humerus wisdom teeth. Perhaps an environmental change made the organ unnecessary for survival, and the organ gradually becomes Radius Ulna Carpals nonfunctional. For instance, the…arrow_forward1.
