Which one of the following clouds are mid-level clouds? A. Cirrocumulus B. Altostratus C. Stratus D. Cirrus - CORRECT ANSWER The correct answer is (B) Altostratus. Mid-level clouds, or middle clouds, occur at altitudes of 6,000 to 20,000 feet. Cirrus = High Clouds, Alto = Middle Clouds, Stratus = Low Clouds. Which of the following are NOT decomposers? A. earthworms B. vultures C. bacteria D. fungi - CORRECT ANSWER The correct answer is (B) vultures. Vultures are considered to be scavengers since they eat dead animals. Decomposers are organisms that break down organic matter from dead animals and plants into simpler substances. Bile is produced by the... A. pancreas B. stomach C. liver D. kidney - CORRECT ANSWER The correct answer is (C) Liver. Bile is a dark, bitter fluid produced continuously by the liver. Bile helps to digest lipids within the small intestine. What kind of rock is formed when existing rock types are changed by heat and pressure? A. Metamorphic B. Igneous C. Sedimentary D. Meteorogical - CORRECT ANSWER The correct answer is (A) Metamorphic. When the original rock is subjected to extreme heat and pressure, profound physical and chemical changes can occur. The three main types of rocks are metamorphic, igneous, and sedimentary. Metamorphic rocks make up a large part of the Earth's crust. Common metamorphic rocks include marble, slate, gneiss, quartzite, and schist. These subatomic particles have a positive electric charge. A. Neutrons B. Protons C. Electrons D. Atoms - CORRECT ANSWER The correct answer is (B) Protons. The basic unit of matter is called the Atom. Atoms consist of a dense nucleus surrounded by a cloud of negatively charged electrons. The nucleus contains a mixture of protons which are positively charged, and neutrons, which are electrically neutral. Which of the following is a characteristic of the autonomic nervous system? A. It regulates the voluntary control of body movements through the skeletal muscles. B. It regulates involuntary activity in the heart, stomach, lungs, and intestines. C. It is thought to be the center of intelligence D. It is the part of the nervous system consisting of the brain and spinal cord. - CORRECT ANSWER The correct answer is (B) It regulates involuntary activity in the heart, stomach, lungs, and intestines. The somatic nervous system controls voluntary actions, while the autonomic nervous system functions primarily below the level of consciousness to control functions such as heart rate, digestion, respiratory rate, salivation, perspiration, breathing, and swallowing. The central nervous system consists of the brain and spinal cord. Which layer of the atmosphere is closest to the earth? A. Mesosphere B. Stratosphere C. Troposphere D. Thermosphere - CORRECT ANSWER The correct answer is (C) Troposphere. The troposphere begins at the Earth's surface and extends up 4-12 miles high. Almost all weather occurs in the Troposphere. Which of Newton's laws proves that: An object at rest will stay at rest unless an external force acts upon it. An object in motion won't change its velocity unless an external force acts upon it. A.Newton's First Law of Motion B.Newton's Second Law of Motion C.Newton's Third Law of Motion D.Newton's Law of Universal Gravitation - CORRECT ANSWER The correct answer is (A) Newton's First Law is often called the law of inertia. Newton's Second Law: Force=Mass x Acceleration. Newton's Third Law: For every action, there is an equal and opposite re-action. The law of conservation of energy can be restated as which of the following? A. The total energy of a system always diminishes B. Energy cannot be created or destroyed, only changed. C. The sum of all of the forces is equivalent to the amount of energy in a system. D. Mechanical and potential energy share an inverse relationship - CORRECT ANSWER The correct answer is (B) Energy cannot be created or destroyed, only changed. The law of conservation of energy states that the total energy of an isolated system remains constant. Energy cannot be created or destroyed, but it can change from one form to another. For example, an object dropped from a rooftop will undergo a change from potential energy to kinetic energy and hit the floor with a force equal to the amount of work done on the object by gravity. The International System (SI) unit of force is which of the following? A. Newton B. Joule C. Watt D. Dyne - CORRECT ANSWER The correct answer is (A) Newton. Force is the product of mass and acceleration. Mass has units of kilograms and acceleration has units of meters per second per second. In honor of Isaac Newton and his equation F=ma, force is measured in newtons. Mitosis is the process by which: A. eukaryotic cells degrade B. energy is liberated C. somatic cells replicate D. ATP is produced. - CORRECT ANSWER The correct answer is (C) somatic cells replicate. Mitosis is the process by which cells replicate their chromosomes. The information contained in the cell's nucleus is duplicated and one cell splits into two. This process occurs in all somatic cells. Which of the following is true of chemical elements? A.
