- fossil record
Q: Answer the following question given this paragraph: 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 ). Q: Fossils themselves and the order in which they appear in are generally collectively called what? A:
Answer: fossil record

Answer the following question given this paragraph: An electric generator is a device that produces electricity through electromagnetic induction. Electromagnetic induction is the process of generating electric current with a magnetic field. Q: What is the process of generating electric current with a magnetic field? A:

A: electromagnetic induction

Answer the following question given this paragraph: In Iceland, the Mid-Atlantic Ridge is above sea level. It's the only place we can see a mid-ocean ridge out of the water. The Midlina Bridge connects two plates. On the west side is the North American plate. On the east side is the Eurasian plate. A mid-ocean ridge is where new crust is created. Eventually this spot will be beneath the Atlantic Ocean. Q: In iceland, the mid-atlantic ridge is above sea what? A:
OPTIONS:
- atmosphere
- bottom
- tide
- level
level

Answer the following question given this paragraph: Examples of objects that have projectile motion include arrows and cannon balls. Q: Arrows and cannon balls are examples of objects with what kind of motion? A:
OPTIONS:
- velocity
- fluid
- accelerating
- projectile

Answer: projectile

Question: Answer the following question given this paragraph: Arterioles An arteriole is a very small artery that leads to a capillary. Arterioles have the same three tunics as the larger vessels, but the thickness of each is greatly diminished. The critical endothelial lining of the tunica intima is intact. The tunica media is restricted to one or two smooth muscle cell layers in thickness. The tunica externa remains but is very thin (see Figure 20.4). With a lumen averaging 30 micrometers or less in diameter, arterioles are critical in slowing downor resistingblood flow and, thus, causing a substantial drop in blood pressure. Because of this, you may see them referred to as resistance vessels. The muscle fibers in arterioles are normally slightly contracted, causing arterioles to maintain a consistent muscle tonein this case referred to as vascular tonein a similar manner to the muscular tone of skeletal muscle. In reality, all blood vessels exhibit vascular tone due to the partial contraction of smooth muscle. The importance of the arterioles is that they will be the primary site of both resistance and regulation of blood pressure. The precise diameter of the lumen of an arteriole at any given moment is determined by neural and chemical controls, and vasoconstriction and vasodilation in the arterioles are the primary mechanisms for distribution of blood flow. Q: A very small artery that leads to a capillary is known as what? A:
OPTIONS:
- capillary junction
- vein
- arterium
- arteriole
Answer: arteriole
