Answer the following question given this paragraph: In saturated fatty acids , carbon atoms are bonded to as many hydrogen atoms as possible. This causes the molecules to form straight chains, as shown in Figure below . The straight chains can be packed together very tightly, allowing them to store energy in a compact form. This explains why saturated fatty acids are solids at room temperature. Animals use saturated fatty acids to store energy. Q: What do animals store with the help of saturated fatty acids? Choices: - oxygen - sugar - protein - energy A:
energy

Answer the following question given this paragraph: Pulmonary circulation is the part of the circulatory system that carries blood between the heart and lungs (the term "pulmonary" means "of the lungs"). It is illustrated in Figure below . Deoxygenated blood leaves the right ventricle through pulmonary arteries, which transport it to the lungs. In the lungs, the blood gives up carbon dioxide and picks up oxygen. The oxygenated blood then returns to the left atrium of the heart through pulmonary veins. Q: What gas do the lungs give up as they take in oxygen? Choices: - carbon monoxide - methane - nitrogen - carbon dioxide A:
(Answer)
carbon dioxide
Ques: Answer the following question given this paragraph: Stems are organs that hold plants upright. They allow plants to get the sunlight and air they need. Stems also bear leaves, flowers, cones, and smaller stems. These structures grow at points called nodes. The stem between nodes is called an internode. (See Figure below . ). Q: What is the basic structure that holds plants upright, allowing plants to get the sunlight and air they need? Choices: - twig - stamen - root - stem A:
Ans: stem
(Q).
Answer the following question given this paragraph: Have you ever experienced heartburn? Heartburn is actually a condition caused by stomach acid, rather something in your heart. The stomach produces HCl, which is a necessary component of digestion. However, excessive amounts of stomach acid can cause a great deal of discomfort. Various factors can cause the overproduction of acid, mostly related to the types (and amounts) of food and beverages that are being consumed. Caffeine and other oils in coffee (even decaf) will increase HCl production in the stomach. Smoking cigarettes and drinking alcohol also increase the formation of stomach acid. Q: What is a common condition caused by stomach acid? Choices: - arthritis - headache - sunburn - heartburn A:
(A).
heartburn
Ques:Answer the following question given this paragraph: Identify evidence for electroweak unification. The quarks in a particle are confined, meaning individual quarks cannot be directly observed. Are gluons confined as well? Explain. Q: The quarks in a particle are confined, meaning individual quarks cannot be what? Choices: - separated - changed - hypothesized - directly observed A:

Ans:directly observed
Answer the following question given this paragraph: Flying birds are divided into 29 orders. The most common orders include landfowl, waterfowl, shorebirds, diurnal and nocturnal raptors, parrots, and perching birds. Q: How many orders can flying birds be divided into? Choices: - 31 - 44 - 19 - 29 A:
29
