Answer the following question given this paragraph: Using fossil fuels and nuclear energy creates other problems as well. The burning of fossil fuels releases carbon dioxide into the atmosphere. This is one of the major greenhouse gases causing global climate change. Nuclear power creates another set of problems, including the disposal of radioactive waste. Q: What gets released into the atmosphere when fossil fuels are burned? Choices: - oxygen - hydrogen - chemical dioxide - carbon dioxide A:
carbon dioxide
Answer the following question given this paragraph: Urinalysis (urine analysis) often provides clues to renal disease. Normally, only traces of protein are found in urine, and when higher amounts are found, damage to the glomeruli is the likely basis. Unusually large quantities of urine may point to diseases like diabetes mellitus or hypothalamic tumors that cause diabetes insipidus. The color of urine is determined mostly by the breakdown products of red blood cell destruction (Figure 25.2). The "heme" of hemoglobin is converted by the liver into water-soluble forms that can be excreted into the bile and indirectly into the urine. This yellow pigment is urochrome. Urine color may also be affected by certain foods like beets, berries, and fava beans. A kidney stone or a cancer of the urinary system may produce sufficient bleeding to manifest as pink or even bright red urine. Diseases of the liver or obstructions of bile drainage from the liver impart a dark "tea" or "cola" hue to the urine. Dehydration produces darker, concentrated urine that may also possess the slight odor of ammonia. Most of the ammonia produced from protein breakdown is converted into urea by the liver, so ammonia is rarely detected in fresh urine. The strong ammonia odor you may detect in bathrooms or alleys is due to the breakdown of urea into ammonia by bacteria in the environment. About one in five people detect a distinctive odor in their urine after consuming asparagus; other foods such as onions, garlic, and fish can impart their own aromas! These food-caused odors are harmless. Q: Normally, only traces of protein are found in urine, and when higher amounts are found, damage to what is the likely cause? Choices: - Hypothyroid - aeration - occidentalis - glomeruli A:
glomeruli
Q: Answer the following question given this paragraph: The external female reproductive structures are referred to collectively as the vulva. They include the labia (singular, labium), which are the "lips" of the vulva. The labia protect the vagina and urethra, both of which have openings in the vulva. Q: The external female reproductive structures are referred to collectively as what? Choices: - the cervix - the uterus - the Fallopian tube - the vulva A:
A: the vulva

Some pushes and pulls can be seen. Q: What pulls skydivers towards the earth? Choices: - momentum - impact - inertia - gravity A:
**Answer**
gravity
Q: Answer the following question given this paragraph: Volcanic eruptions can be devastating, particularly to the people who live close to volcanoes. Volcanologists study volcanoes to be able to predict when a volcano will erupt. Many changes happen when a volcano is about to erupt. Q: Who study volcanoes to be able to predict when a volcano will erupt? Choices: - vocologists - virologists - ornithologists - volcanologists A:
A: volcanologists
