Q: 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:
A: in their cecum

Q: Answer the following question given this paragraph: called the relative osmotic pressure if neither solution is pure water, and it is called the osmotic pressure if one solution is pure water. Osmotic pressure can be large, depending on the size of the concentration difference. For example, if pure water and sea water are separated by a semipermeable membrane that passes no salt, osmotic pressure will be 25.9 atm. This value means that water will diffuse through the membrane until the salt water surface rises 268 m above the pure-water surface! One example of pressure created by osmosis is turgor in plants (many wilt when too dry). Turgor describes the condition of a plant in which the fluid in a cell exerts a pressure against the cell wall. This pressure gives the plant support. Dialysis can similarly cause substantial pressures. Q: What is the condition of a plant in which the fluid in a cell exerts a pressure against the cell wall? Choices: - constriction - tumor - hydration - turgor A:
A: turgor

Q: Answer the following question given this paragraph: This bacterium, called Mycobacterium tuberculosis , causes the disease Tuberculosis (TB). These bacteria usually attack the lungs. If left untreated, the infection can be fatal. Many other illnesses, mild and severe, are also caused by certain types of bacteria. Q: What part of the body does the mycobacterium tuberculosis bacterium usually attack? Choices: - Pancreas - muscles - heart - lungs A:
A: lungs

Q: Answer the following question given this paragraph: All the other nervous tissues in the body are part of the peripheral nervous system. If you look again at Figure above , you can see the major nerves of the peripheral nervous system. They include nerves that run through virtually every part of the body, both inside and out, except for the brain and spinal cord. Q: The peripheral nervous system has major nerves that travel through every part of the body except which two places? Choices: - muscles and brain - lungs and spinal cord - brain and heart - brain and spinal cord A:
A: brain and spinal cord
