Q: Our sun is on the main sequence, like most stars, and it is classified by what colorful name? Read this paragraph and choose the correct option from the provided answers: We have a main sequence star nearby. Our Sun is on the main sequence, classified as a yellow dwarf. Our Sun has been a main sequence star for about 5 billion years. As a medium-sized star, it will continue to shine for about 5 billion more years. Most stars are on the main sequence. Choices: - white dwarf - blue dwarf - red dwarf - yellow dwarf A:
yellow dwarf

Q: What is a strombolian eruption named for? Read this paragraph and choose the correct option from the provided answers: This is a strombolian eruption. This type of eruption was named for Mt. Stromboli in Italy. Strombolian eruptions spew lava into the air. But these eruptions do not have a massive explosion. They create lava flows. Choices: - an ice cleaner - a country - mt. st. helens - mt. stromboli A:
(Answer)
mt. stromboli

Ques: Q: Inside the nasal area of the skull, the nasal cavity is divided into halves by the what? Read this paragraph and choose the correct option from the provided answers: Inside the nasal area of the skull, the nasal cavity is divided into halves by the nasal septum. The upper portion of the nasal septum is formed by the perpendicular plate of the ethmoid bone and the lower portion is the vomer bone. Each side of the nasal cavity is triangular in shape, with a broad inferior space that narrows superiorly. When looking into the nasal cavity from the front of the skull, two bony plates are seen projecting from each lateral wall. The larger of these is the inferior nasal concha, an independent bone of the skull. Located just above the inferior concha is the middle nasal concha, which is part of the ethmoid bone. A third bony plate, also part of the ethmoid bone, is the superior nasal concha. It is much smaller and out of sight, above the middle concha. The superior nasal concha is located just lateral to the perpendicular plate, in the upper nasal cavity. Choices: - cerebral cortex - cytoplasm - cell wall - nasal septum A:
Ans: nasal septum

(Q).
Q: What is formed when a monomer of glucose and a monomer of fructose are joined in a dehydration reaction to form a glycosidic bond? Read this paragraph and choose the correct option from the provided answers: Figure 3.7 Sucrose is formed when a monomer of glucose and a monomer of fructose are joined in a dehydration reaction to form a glycosidic bond. In the process, a water molecule is lost. By convention, the carbon atoms in a monosaccharide are numbered from the terminal carbon closest to the carbonyl group. In sucrose, a glycosidic linkage is formed between carbon 1 in glucose and carbon 2 in fructose. Choices: - fructose - sulfate - chloride - sucrose A:
(A).
sucrose

Ques:Q: Which bone is derived from the fusion of four very small coccygeal vertebrae? Read this paragraph and choose the correct option from the provided answers: The body can also respond effectively to short-term exposure to cold. One response to cold is shivering, which is random muscle movement that generates heat. Another response is increased breakdown of stored energy to generate heat. When that energy reserve is depleted, however, and the core temperature begins to drop significantly, red blood cells will lose their ability to give up oxygen, denying the brain of this critical component of ATP production. This lack of oxygen can cause confusion, lethargy, and eventually loss of consciousness and death. The body responds to cold by reducing blood circulation to the extremities, the hands and feet, in order to prevent blood from cooling there and so that the body's core can stay warm. Even when core body temperature remains stable, however, tissues exposed to severe cold, especially the fingers and toes, can develop frostbite when blood flow to the extremities has been much reduced. This form of tissue damage can be permanent and lead to gangrene, requiring amputation of the affected region. Choices: - cranium - clavicle - femur - coccyx A:

Ans:coccyx

Ques:Q: Group 16 is called what? Read this paragraph and choose the correct option from the provided answers: Group 16 is called the oxygen group. The first three elements in this group are nonmetals. They are followed by one metalloid and one metal. All the elements in the oxygen group have six valence electrons, and all are reactive. Oxygen (O), for example, readily reacts with metals to form compounds such as rust. Oxygen is a gas at room temperature. The other four elements in group 16 are solids. Choices: - noble gases - the acid group - metalloids - the oxygen group A:

Ans:
the oxygen group
