Answer the following question given this paragraph: As has been noted in numerous Things Great and Small vignettes, this is not the first time the large has been explained by the small and vice versa. Newton realized that the nature of gravity on Earth that pulls an apple to the ground could explain the motion of the moon and planets so much farther away. Minute atoms and molecules explain the chemistry of substances on a much larger scale. Decays of tiny nuclei explain the hot interior of the Earth. Fusion of nuclei likewise explains the energy of stars. Today, the patterns in particle physics seem to be explaining the evolution and character of the universe. And the nature of the universe has implications for unexplored regions of particle physics. Cosmology is the study of the character and evolution of the universe. What are the major characteristics of the universe as we know them today? First, there are approximately 10 11 galaxies in the observable part of the universe. An average galaxy contains more than 10 11 stars, with our Milky Way galaxy being larger than average, both in its number of stars and its dimensions. Ours is a spiral-shaped galaxy with a diameter of about 100,000 light years and a thickness of about 2000 light years in the arms with a central bulge about 10,000 light years across. The Sun lies about 30,000 light years from the center near the galactic plane. There are significant clouds of gas, and there is a halo of less-dense regions of stars surrounding the main body. (See Figure 34.3. ) Evidence strongly suggests the existence of a large amount of additional matter in galaxies that does not produce lightthe mysterious dark matter we shall later discuss. Q: Newton realized that the nature of gravity on earth that pulls an apple to the ground could explain the motion of these? Choices: - seasons - atoms and quarks - molecules - moon and planets A:
moon and planets

Answer the following question given this paragraph: extensors are the triceps brachii and anconeus. The pronators are the pronator teres and the pronator quadratus, and the supinator is the only one that turns the forearm anteriorly. When the forearm faces anteriorly, it is supinated. When the forearm faces posteriorly, it is pronated. The biceps brachii, brachialis, and brachioradialis flex the forearm. The two-headed biceps brachii crosses the shoulder and elbow joints to flex the forearm, also taking part in supinating the forearm at the radioulnar joints and flexing the arm at the shoulder joint. Deep to the biceps brachii, the brachialis provides additional power in flexing the forearm. Finally, the brachioradialis can flex the forearm quickly or help lift a load slowly. These muscles and their associated blood vessels and nerves form the anterior compartment of the arm (anterior flexor compartment of the arm) (Figure 11.25 and Figure 11.26). Q: Biceps brachii, brachialis, and brachioradialis work to flex what part of the body? Choices: - leg - foot - lungs - forearm A:
(Answer)
forearm
Ques: Answer the following question given this paragraph: Many adults and some children suffer from a deficiency of lactase. These individuals are said to be lactose intolerant because they cannot digest the lactose found in milk. A more serious problem is the genetic disease galactosemia, which results from the absence of an enzyme needed to convert galactose to glucose. Certain bacteria can metabolize lactose, forming lactic acid as one of the products. This reaction is responsible for the "souring" of milk. Q: Many adults and some children suffer from a deficiency of lactase. these individuals are said to be lactose intolerant because they cannot digest the lactose found in what? Choices: - fruit - peanuts - meat - milk A:
Ans: milk

Answer the following question given this paragraph: A migraine is a more severe type of headache. It occurs when blood vessels in the head dilate, or expand. This may be triggered by certain foods, bright lights, weather changes, or other factors. People with migraines may also have nausea or other symptoms. Fortunately, migraines can often be relieved with prescription drugs. Q: When blood vessels in the head dilate, what kind of severe headache can occur? Choices: - malignant - chronic headache - tension headache - migraine A:
(A).
migraine
Ques:Answer the following question given this paragraph: Outdoor air pollution is made of chemical particles. When smoke or other pollutants enter the air, the particles found in the pollution mix with the air. Air is polluted when it contains many large toxic particles. Outdoor air pollution changes the natural characteristics of the atmosphere. Primary pollutants are added directly to the atmosphere. Fires add primary pollutants to the air. Particles released from the fire directly enter the air and cause pollution ( Figure below ). Burning of fossil fuels such as oil and coal is a major source of primary pollutants ( Figure below ). Q: A major source of primary pollutants is the burning of oil and coal, which are types of what? Choices: - erosion fuels - renewable fuels - greenhouse gases - fossil fuels A:

Ans:fossil fuels
Ques:Answer the following question given this paragraph: Q: What tissue system has neither dermal nor vascular tissues? Choices: - external tissue system - work tissue system - internal tissue system - ground tissue system A:

Ans:
ground tissue system
