Chimpanzees have their vocal cords situated higher in the pharynx than in humans. All mammal species can choke (obstruction of windpipe) on food. The fact that we can choke on our food is an evolutionary compromise that is largely compensated that we have the capacity to speak.

How does the anatomy of the digestive system influence the food preference of the perch, compared to that of the shark? What is the comparison of both the shark and the perch in their buoyancy mechanisms and their oxygen/carbon dioxide exchange? Please answer this fully because last time someone didn't answer this correctly and wasted one of my question credits.
- Which statement is false? Chimpanzees have their vocal cords situated higher in the pharynx than in humans. All mammal species can choke (obstruction of windpipe) on food. The fact that we can choke on our food is an evolutionary compromise that is largely compensated that we have the capacity to speak. Choking is partly a consequence of the fact that there is a space between the posterior end of the soft palate and the dorsal tip of the epiglottis. Salmonella, a gram-negative bacterium, produces an endotoxin that causes food poisoning. What is endotoxin? Secretion of the bacterium that becomes toxic only when it enters the cells of the digestive tract. A toxin accumulated in the wall of the bacteria in his life and that is released into the host when the bacteria dies. A toxic substance produced by living bacteria and secreted directly on the host cells (in the intestine). None of these answers defines an endotoxin.Fetal Pig Oral Cavity Please refer to the pic to answer the question Describe the color, texture, and functions of the fetal pig's oral cavity. Compare the features of the pig's oral cavity to that of the frogs. What features of the pigs oral cavity are also found in that of humans? What differences are there? Describe the pigs teeth. Also what prevents food from entering the glottis or nasopharynx and what happens when the food does enter either of those two openings?Which of the following is the correct classification for the following chordate animal: This is a tetrapod vertebrate that may live its live partly in water and partly on land (some species fully aquatic). These animals have a tail and most of them are lungless. They respire through their skin or gills. Question 28 options: a) Class Chondrichthyes b) Monotreme c) Cephalochordata d) Reptiles (non avian) e) Birds f) Urodela / Salamanders g) Anura / Frogs h) Eutharia i) Class Osteichthyes j) Marsupial k) Superclass Agnatha
- Human anatomy is rather good, thanks to evolution. However, can you think of ways to improve it? For example, allow females to have four breasts instead of two - useful for breastfeeding multiple births. Append an extra pair of arms - useful for carrying things and performing tasks. Have an intake port for food that is separate from the orifice used for talking/breathing - we could eat and talk at the same time and be less likely to choke on our food. Add an extra eye - perhaps in the back of our head? Add a third kidney. Have a way to store oxygen for the brain so that we can withstand interruption to breathing for longer. Have a blood supply to the myocardium that has more anastomoses so that blood can navigate around blockages to the coronary arteries. A wider or more elastic birth canal so that birth can be accomplished more rapidly and with less drama. Eliminate the appendix. Have the ability to digest cellulose, etc. (Do not consider the imaginary powers of "superheroes".)…In which of the following animals, single opening is used for both ingestion and egestion while removal of metabolic waste products is through body wall? a.Hydra and Obelia b.Taenia and Fasciola c.Nereis and Hirudinaria d.Limulus and LocustaBirds differ from their closest relatives, the reptiles, in what ways? (choose all that apply) birds are capable of powered flight, while some reptiles can glide only the birds lay eggs on land; the reptiles can only lay their eggs in water birds have feathers, reptiles have scales the reptiles have a series of internal air sacs that allow a very efficient extraction of oxygen the bones of reptiles are too lightweight to permit flight birds are endothermic, while reptiles are generally ectothermic
