Answer the following question given this paragraph: An object will not change its state of motion (i. e. , accelerate) unless an unbalanced force acts on it. Equal and oppositely directed forces on the same object do not produce acceleration. Q: An unbalanced force on an object in motion causes what? Choices: - agitation - velocity - vibration - acceleration A:
acceleration

Answer the following question given this paragraph: Unsaturated fat is generally considered to be healthier because it contains fewer calories than an equivalent amount of saturated fat. Additionally, high consumption of saturated fats is linked to an increased risk of cardiovascular disease. Some examples of foods with high concentrations of saturated fats include butter, cheese, lard, and some fatty meats. Foods with higher concentrations of unsaturated fats include nuts, avocado, and vegetable oils such as canola oil and olive oil. The Figure below shows the percentages of fat types in some common foods. Q: High consumption of saturated fats is linked to an increased risk of what disease? Choices: - pulmonary edema - high blood pressure - diabetes - cardiovascular disease A:
(Answer)
cardiovascular disease
Ques: Answer the following question given this paragraph: Q: Do motile cilia usually occur in small or large numbers on the cell surface? Choices: - neither - mixed - small - large A:
Ans: large
(Q).
Answer the following question given this paragraph: Aggressive behavior often occurs when individuals compete for the same resources. Animals may compete for territory, water, food, or mates. There are two basic types of competition: intraspecific and interspecific. Q: What are the two basic types of competition called? Choices: - exploitative and beneficial - weak and strong - interference and interaction - instraspecifc and interspecific A:
(A).
instraspecifc and interspecific
Ques:Answer the following question given this paragraph: The concentration of copper ions in the solution is effectively constant. This is because the electroplating process transfers metal from the anode to the cathode of the cell. Other metals commonly plated onto objects include chromium, gold, silver, and platinum. Q: The electroplating process transfers metal from the anode to which part of the cell? Choices: - plasma - electrode - atom tube - cathode A:

Ans:cathode
Ques: Answer the following question given this paragraph: Chemical Digestion in the Small Intestine The digestion of proteins and carbohydrates, which partially occurs in the stomach, is completed in the small intestine with the aid of intestinal and pancreatic juices. Lipids arrive in the intestine largely undigested, so much of the focus here is on lipid digestion, which is facilitated by bile and the enzyme pancreatic lipase. Moreover, intestinal juice combines with pancreatic juice to provide a liquid medium that facilitates absorption. The intestine is also where most water is absorbed, via osmosis. The small intestine's absorptive cells also synthesize digestive enzymes and then place them in the plasma membranes of the microvilli. This distinguishes the small intestine from the stomach; that is, enzymatic digestion occurs not only in the lumen, but also on the luminal surfaces of the mucosal cells. For optimal chemical digestion, chyme must be delivered from the stomach slowly and in small amounts. This is because chyme from the stomach is typically hypertonic, and if large quantities were forced all at once into the small intestine, the resulting osmotic water loss from the blood into the intestinal lumen would result in potentially life-threatening low blood volume. In addition, continued digestion requires an upward adjustment of the low pH of stomach chyme, along with rigorous mixing of the chyme with bile and pancreatic juices. Both processes take time, so the pumping action of the pylorus must be carefully controlled to prevent the duodenum from being overwhelmed with chyme. Q: What two types of juices help digestion within the small intestine? Choices: - chyme and phloem - amniotic fluid, bile - bile and lymph - intestinal and pancreatic A:
Ans:
intestinal and pancreatic
