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:
in their cecum

Answer the following question given this paragraph: Using fossil fuels affects the environment in a variety of ways. There are impacts to the environment when we extract these resources. Burning these fuels causes air pollution. These fuels release carbon dioxide, which is a major factor in global warming ( Figure below ). Q: What gas is released by burning of fossil fuels and contributes to global warming? Choices: - nitrous oxide - hydrogen - helium - carbon dioxide A:
(A).
carbon dioxide
Ques:Answer the following question given this paragraph: The parts of the ears involved in balance are the semicircular canals. These are the curved structures above the cochlea in the inner ear in Figure above . Like the cochlea, the semicircular canals contain liquid and are lined with tiny hair cells. As the head changes position, the liquid moves. This causes the hair cells to bend. The bending of the hair cells triggers nerve impulses that travel to the cerebellum in the brain. The cerebellum uses the information to maintain balance. Q: Involved in balance, the semicircular canals are parts of what organs? Choices: - eyes - lungs - ovaries - ears A:

Ans:ears
Ques:Answer the following question given this paragraph: Hydraulic fracturing, known as fracking, is a relatively new method for extracting natural gas. Fracking may be linked to groundwater contamination and small earthquakes in non-seismic regions. Q: What is another term for hydraulic fracturing? Choices: - erupting - permeating - drilling - fracking A:

Ans:
fracking
