Answer the following question given this paragraph: Q: Living things need to take in nutrients so that they can grow and create what? Choices: - protein - plasma - hydrogen - energy A:

Answer the following question given this paragraph: Sometimes large numbers of species go extinct in a short amount of time. This is a mass extinction . The causes of different mass extinctions are different: collisions with comets or asteroids, massive volcanic eruptions, or rapidly changing climate are all possible causes of some of these disasters ( Figure below ). Q: What term is used to describe large numbers of species that go extinct in a short amount of time? Choices: - formation extinction - organic extinction - species extinction - mass extinction A:
mass extinction
Q: Answer the following question given this paragraph: 43.5 | Human Pregnancy and Birth By the end of this section, you will be able to: Explain fetal development during the three trimesters of gestation Describe labor and delivery Compare the efficacy and duration of various types of contraception Discuss causes of infertility and the therapeutic options available Pregnancy begins with the fertilization of an egg and continues through to the birth of the individual. The length of time of gestation varies among animals, but is very similar among the great apes: human gestation is 266 days, while chimpanzee gestation is 237 days, a gorilla's is 257 days, and orangutan gestation is 260 days long. The fox has a 57-day gestation. Dogs and cats have similar gestations averaging 60 days. The longest gestation for a land mammal is an African elephant at 640 days. The longest gestations among marine mammals are the beluga and sperm whales at 460 days. Q: What land mammal has the longest gestation period? Choices: - Rhino - Giraffe - Asian elephant - african elephant A:
A: african elephant
Question: Answer the following question given this paragraph: One common application of inductance is used in traffic lights that can tell when vehicles are waiting at the intersection. An electrical circuit with an inductor is placed in the road under the place a waiting car will stop over. The body of the car increases the inductance and the circuit changes sending a signal to the traffic lights to change colors. Similarly, metal detectors used for airport security employ the same technique. A coil or inductor in the metal detector frame acts as both a transmitter and a receiver. The pulsed signal in the transmitter coil induces a signal in the receiver. The self-inductance of the circuit is affected by any metal object in the path. Such detectors can be adjusted for sensitivity and also can indicate the approximate location of metal found on a person. (But they will not be able to detect any plastic explosive such as that found on the "underwear bomber. ") See Figure 23.43. Q: Metal detectors used for airport security work on which principle? Choices: - electricity - inertia - conductivity - inductance A:
Answer: inductance

Answer the following question given this paragraph: To grow and develop, you must form new cells. Imagine how often your cells must divide during a growth spurt. Growing just an inch requires countless cell divisions. Your body must produce new bone cells, new skin cells, new cells in your blood vessels and so on. Q: A growth spurt requires constant divisions of what? Choices: - hairs - seeds - proteins - cells A:
**Answer**
cells

Answer the following question given this paragraph: A genetic disorder that is caused by a mutation can be inherited. Therefore, people with a genetic disorder in their family may be concerned about having children with the disorder. Professionals known as genetic counselors can help them understand the risks of their children being affected. If they decide to have children, they may be advised to have prenatal ("before birth") testing to see if the fetus has any genetic abnormalities. One method of prenatal testing is amniocentesis . In this procedure, a few fetal cells are extracted from the fluid surrounding the fetus, and the fetal chromosomes are examined. Q: What measure is resorted to by people who wish to screen out genetic abnormalities in the fetus? Choices: - contraceptive use - in vitro fertilization - stem cell therapy - prenatal testing A:
(Answer)
prenatal testing
