Answer the following question given this paragraph: Mitosis vs. Meiosis Comparison. Mitosis produces two diploid daughter cells, genetically identical to the parent cell. Meiosis produces four haploid daughter cells, each genetically unique. See How Cells Divide: Mitosis vs. Meiosis at http://www. pbs. org/wgbh/nova/miracle/divide. html for an animation comparing the two processes. Q: What process produces four haploid daughter cells, each genetically unique? Choices: - electrolysis - budding - mitosis - meiosis A:
meiosis
Answer the following question given this paragraph: Hot spots are found within continents, but not as commonly as within oceans. The Yellowstone hot spot is a famous example of a continental hot spot. Q: The yellowstone hot spot is a famous example of a what? Choices: - form hot spot - oceanic hot spot - deeper hot spot - continental hot spot A:
continental hot spot
Q: Answer the following question given this paragraph: The nuclear envelope is a double membrane of the nucleus that encloses the genetic material. It separates the contents of the nucleus from the cytoplasm. The nuclear envelope is made of two lipid bilayers, an inner membrane and an outer membrane. The outer membrane is continuous with the rough endoplasmic reticulum. Many tiny holes called nuclear pores are found in the nuclear envelope. These nuclear pores help to regulate the exchange of materials (such as RNA and proteins) between the nucleus and the cytoplasm. Q: What is a double membrane of the nucleus that encloses the genetic material? Choices: - cell wall - cell membrane - nuclear wall - nuclear enevelope A:
A: nuclear enevelope
Question: Answer the following question given this paragraph: Avian Birds face special challenges when it comes to obtaining nutrition from food. They do not have teeth and so their digestive system, shown in Figure 34.7, must be able to process un-masticated food. Birds have evolved a variety of beak types that reflect the vast variety in their diet, ranging from seeds and insects to fruits and nuts. Because most birds fly, their metabolic rates are high in order to efficiently process food and keep their body weight low. The stomach of birds has two chambers: the proventriculus, where gastric juices are produced to digest the food before it enters the stomach, and the gizzard, where the food is stored, soaked, and mechanically ground. The undigested material forms food pellets that are sometimes regurgitated. Most of the chemical digestion and absorption happens in the intestine and the waste is excreted through the cloaca. Q: In which part of a bird stomach is food stored, soaked and mechanically ground? Choices: - pancreas - digestion - Gall bladder - gizzard A:
Answer: gizzard

Answer the following question given this paragraph: Osteoporosis is a disease in which bones lose mass and become more fragile than they should be. Osteoporosis also makes bones more likely to break. Two of the easiest ways to prevent osteoporosis are eating a healthy diet that has the right amount of calcium and vitamin D and to do some sort of weight-bearing exercise every day. Foods that are a good source of calcium include milk, yogurt, and cheese. Non-dairy sources of calcium include Chinese cabbage, kale, and broccoli. Many fruit juices, fruit drinks, tofu, and cereals have calcium added to them. It is recommended that teenagers get 1300 mg of calcium every day. For example, one cup (8 fl. oz. ) of milk provides about 300 mg of calcium, or about 30% of the daily requirement. Q: What is the disease in which bones lose mass and become more fragile and likely to break? Choices: - arthritis - tuberculosis - fibrosis - osteoporosis A:
(Answer)
osteoporosis
