Q: Q: Fossils themselves and the order in which they appear in are generally collectively called what? Read this paragraph and choose the correct option from the provided answers: There are many layers of rock in the Earth's surface. Newer layers form on top of the older layers; the deepest rock layers are the oldest. Therefore, you can tell how old a fossil is by observing in which layer of rock it was found. The fossils and the order in which fossils appear is called the fossil record . The fossil record provides evidence for when organisms lived on Earth, how species evolved, and how some species have gone extinct. Geologists use a method called radiometric dating to determine the exact age of rocks and fossils in each layer of rock. This technique, which is possible because radioactive materials decay at a known rate, measures how much of the radioactive materials in each rock layer have broken down ( Figure below ). Choices: - fossil magnitude - coal record - fuel cycle - fossil record A:
A: fossil record

Q: Q: Which muscles raise the hyoid bone, the floor of the mouth, and the larynx during deglutition? Read this paragraph and choose the correct option from the provided answers: The suprahyoid muscles raise the hyoid bone, the floor of the mouth, and the larynx during deglutition. These include the digastric muscle, which has anterior and posterior bellies that work to elevate the hyoid bone and larynx when one swallows; it also depresses the mandible. The stylohyoid muscle moves the hyoid bone posteriorly, elevating the larynx,. Choices: - spicule - spirogyra - Hybrid - suprahyoid A:
A: suprahyoid

Q: Q: Speciation, convergent evolution, and coevolution are types of what process? Read this paragraph and choose the correct option from the provided answers: Macroevolution occurs when microevolution takes place over a long period of time. Types of macroevolution include speciation, convergent evolution, and coevolution. Choices: - devolution - systemic evolution - microevolution - macroevolution A:
A: macroevolution

Q: Q: What is the term for preserved remains or traces of organisms that lived in the past? Read this paragraph and choose the correct option from the provided answers: Fossils are preserved remains or traces of organisms that lived in the past. Most fossils form in sedimentary rock. Fossils can also be preserved in other ways. Fossilization is rare. It's very unlikely for any given organism to become a fossil. Choices: - deposits - bones - remains - fossils A:
A: fossils
