Answer the following question given this paragraph: Since the early 1990s, astronomers have discovered other solar systems. A solar system has one or more planets orbiting one or more stars. We call these planets "extrasolar planets," or exoplanets . They are called exoplanets because they orbit a star other than the Sun. As of April 2014, more than 4,600 exoplanets have been found, with 1706 confirmed. The rate of discovery is increasing rapidly! You can check out how many we have found at http://planetquest. jpl. nasa. gov/ . Q: What do you call a system that has one or more planets orbiting one or more stars? A:

OPTIONS:
- galaxy
- atom
- molecular system
- solar system

Answer: solar system

Problem: OPTIONS:
- mass pressure
- avalanche
- mass momentum
- mass movement
Q: Answer the following question given this paragraph: Gravity can pull soil, mud, and rocks down cliffs and hillsides. This is called mass movement. The most destructive types of mass movement are landslides and mudslides. They occur suddenly and without warming. They engulf everything in their path. Q: What is the term for when gravity pulls soil, mud, and rocks down cliffs and hillsides? A:
Answer: mass movement

Problem:OPTIONS:
- worms
- bacteria
- fungi
- coral

Answer the following question given this paragraph: What's at the bottom of the food chain? A bit of the food energy comes from above, where plankton photosynthesize. Most comes from the coral. Coral are animals that live with tiny zooxanthellae that also photosynthesize. Of course, you know what's at the top of this food chain!. Q: What are animals that live with tiny zooxanthellae that also photosynthesize? A:
****
A: coral

Answer the following question given this paragraph: Kidneys The kidneys participate in several complex endocrine pathways and produce certain hormones. A decline in blood flow to the kidneys stimulates them to release the enzyme renin, triggering the renin-angiotensin-aldosterone (RAAS) system, and stimulating the reabsorption of sodium and water. The reabsorption increases blood flow and blood pressure. The kidneys also play a role in regulating blood calcium levels through the production of calcitriol from vitamin D3, which is released in response to the secretion of parathyroid hormone (PTH). In addition, the kidneys produce the hormone erythropoietin (EPO) in response to low oxygen levels. EPO stimulates the production of red blood cells (erythrocytes) in the bone marrow, thereby increasing oxygen delivery to tissues. You may have heard of EPO as a performance-enhancing drug (in a synthetic form). Q: A decline in blood flow to what organs stimulates release of the enzyme renin, in turn stimulating the reabsorption of sodium and water? A:
OPTIONS:
- thyroids
- kidneys
- lungs
- kidneys
kidneys

Answer the following question given this paragraph: Q: Some membrane proteins that actively transport ions contribute to what? A:
OPTIONS:
- organism potential
- protein potential
- cellular potential
- membrane potential

Answer: membrane potential

input with options: Answer the following question given this paragraph: Telomerase and Aging Cells that undergo cell division continue to have their telomeres shortened because most somatic cells do not make telomerase. This essentially means that telomere shortening is associated with aging. With the advent of modern medicine, preventative health care, and healthier lifestyles, the human life span has increased, and there is an increasing demand for people to look younger and have a better quality of life as they grow older. In 2010, scientists found that telomerase can reverse some age-related conditions in mice. This may have potential in [2] regenerative medicine. Telomerase-deficient mice were used in these studies; these mice have tissue atrophy, stem 2. Jaskelioff et al. , "Telomerase reactivation reverses tissue degeneration in aged telomerase-deficient mice," Nature 469 (2011): 102-7. Q: Cells that undergo cell division continue to have their telomeres shortened, thus telomere shortening is associated with what life process? A:
OPTIONS:
- metabolism
- reducing
- reproduction
- aging
output:
aging
