Answer the following question given this paragraph: 34.3 Digestive System Processes Digestion begins with ingestion, where the food is taken in the mouth. Digestion and absorption take place in a series of steps with special enzymes playing important roles in digesting carbohydrates, proteins, and lipids. Elimination describes removal of undigested food contents and waste products from the body. While most absorption occurs in the small intestines, the large intestine is responsible for the final removal of water that remains after the absorptive process of the small intestines. The cells that line the large intestine absorb some vitamins as well as any leftover salts and water. The large intestine (colon) is also where feces is formed. Q: Where are feces formed? Choices: - duodenum - liver - small intestine - large intestine A:
large intestine
Answer the following question given this paragraph: A radioisotope has atoms with unstable nuclei. Unstable nuclei naturally decay, or break down. They lose energy and particles and become more stable. As nuclei decay, they gain or lose protons, so the atoms become different elements. This is illustrated in the Figure below . The original, unstable nucleus is called the parent nucleus. After it loses a particle (in this case a type of particle called an alpha particle), it forms a daughter nucleus, with a different number of protons. Q: What has atoms with unstable nuclei? Choices: - hydrocarbon - microwaves - radionuclide - radioisotope A:
radioisotope
Q: Answer the following question given this paragraph: Particles of gas are constantly moving in all directions at random. As a result, they are always bumping into each other and other things. This is modeled in the Figure below . The force of the particles against things they bump into creates pressure. Pressure is defined in physics as the amount of force pushing against a given area. How much pressure a gas exerts depends on the number of gas particles in a given space and how fast they are moving. The more gas particles there are and the faster they are moving, the greater the pressure they create.

Q: What is defined in physics as the amount of force pushing against a given area? Choices: - energy - gravity - resistance - pressure A:
A: pressure
Question: Answer the following question given this paragraph: Q: Resemblance to other species can serve as protection to what category of species? Choices: - producer - predator - consumer - prey A:
Answer: prey

Answer the following question given this paragraph: Pseudo-ruminants Some animals, such as camels and alpacas, are pseudo-ruminants. They eat a lot of plant material and roughage. Digesting plant material is not easy because plant cell walls contain the polymeric sugar molecule cellulose. The digestive enzymes of these animals cannot break down cellulose, but microorganisms present in the digestive system can. Therefore, the digestive system must be able to handle large amounts of roughage and break down the cellulose. Pseudo-ruminants have a threechamber stomach in the digestive system. However, their cecuma pouched organ at the beginning of the large intestine containing many microorganisms that are necessary for the digestion of plant materialsis large and is the site where the roughage is fermented and digested. These animals do not have a rumen but have an omasum, abomasum, and reticulum. Q: Where is roughage fermented and digested in pseudo-ruminants? Choices: - in their ileum - in their appendix - in their pancreas - in their cecum A:
**Answer**
in their cecum
