Q: What branch of biology uses fossils to study life's history? Read this paragraph and choose the correct option from the provided answers: Paleontology, another branch of biology, uses fossils to study life's history (Figure 1.20). Zoology and botany are the study of animals and plants, respectively. Biologists can also specialize as biotechnologists, ecologists, or physiologists, to name just a few areas. This is just a small sample of the many fields that biologists can pursue. Biology is the culmination of the achievements of the natural sciences from their inception to today. Excitingly, it is the cradle of emerging sciences, such as the biology of brain activity, genetic engineering of custom organisms, and the biology of evolution that uses the laboratory tools of molecular biology to retrace the earliest stages of life on earth. A scan of news headlineswhether reporting on immunizations, a newly discovered species, sports doping, or a genetically-modified fooddemonstrates the way biology is active in and important to our everyday world. Choices: - morphology - entomology - gerontology - paleontology A:
(Answer)
paleontology

Q: Instruments that measure the angle of the slope of a volcano are called what? Read this paragraph and choose the correct option from the provided answers: All that magma and gas pushing upward can make the volcano's slope begin to swell. Ground swelling may change the shape of a volcano or cause rock falls and landslides. Most of the time, the ground tilting is not visible. Scientists detect it by using tiltmeters, which are instruments that measure the angle of the slope of a volcano. Choices: - aberration meters - velocity meters - angle meters - tilt meters A:
(Answer)
tilt meters

Q: When you change a magnetic field through electromagnetic induction what do you create? Read this paragraph and choose the correct option from the provided answers: The process of generating electric current with a changing magnetic field is called electromagnetic induction . It occurs whenever a magnetic field and an electric conductor, such as a coil of wire, move relative to one another. As long as the conductor is part of a closed circuit, current will flow through it whenever it crosses magnetic field lines. One way this can happen is pictured in Figure below . It shows a magnet moving inside a wire coil. Another way is for the coil to move instead of the magnet. Choices: - cooling current - microwave current - Light Current - electric current A:
(Answer)
electric current
