Q: How much time does the moon take to complete one revolution around the earth? Read this paragraph and choose the correct option from the provided answers: Choices: - one year - one day - one week - one month A:
one month

Q: When continental crust is pulled apart, it breaks into blocks that are separated by what? Read this paragraph and choose the correct option from the provided answers: When continental crust is pulled apart, it breaks into blocks. These blocks of crust are separated by normal faults. The blocks slide up or down. The result is alternating mountain ranges and valleys. This topography is known as basin-and-range ( Figure below ). The area near Death Valley, California is the center of a classic basin-and-range province ( Figure below ). Choices: - layers - levels - holes - faults A:
(Answer)
faults

Ques: Q: Upwelling mantle at the mid-ocean ridge pushes plates in which direction? Read this paragraph and choose the correct option from the provided answers: Plates move for two reasons. Upwelling mantle at the mid-ocean ridge pushes plates outward. Cold lithosphere sinking into the mantle at a subduction zone pulls the rest of the plate down with it. Choices: - eastward - inward - westward - outward A:
Ans: outward

Q: What term refers to change in position over time? Read this paragraph and choose the correct option from the provided answers: Velocity is defined as change in position over time. Can you see that would be the slope of this graph? (slope = rise over run and in this case the 'rise' is position and the 'run' is time). Find the instantaneous speed at sec. Choices: - Position Replacement - acceleration - Direction Replacement - velocity A:
(A).
velocity

Ques:Q: Which process breaks down glucose to extract energy for cell metabolism? Read this paragraph and choose the correct option from the provided answers: Glycolysis You have read that nearly all of the energy used by living things comes to them in the bonds of the sugar, glucose. Glycolysis is the first step in the breakdown of glucose to extract energy for cell metabolism. Many living organisms carry out glycolysis as part of their metabolism. Glycolysis takes place in the cytoplasm of most prokaryotic and all eukaryotic cells. Glycolysis begins with the six-carbon, ring-shaped structure of a single glucose molecule and ends with two molecules of a three-carbon sugar called pyruvate. Glycolysis consists of two distinct phases. In the first part of the glycolysis pathway, energy is used to make adjustments so that the six-carbon sugar molecule can be split evenly into two three-carbon pyruvate molecules. In the second part of glycolysis, ATP and nicotinamide-adenine dinucleotide (NADH) are produced (Figure 4.13). If the cell cannot catabolize the pyruvate molecules further, it will harvest only two ATP molecules from one molecule of glucose. For example, mature mammalian red blood cells are only capable of glycolysis, which is their sole source of ATP. If glycolysis is interrupted, these cells would eventually die. Choices: - photosynthesis - meiosis - mitosis - glycolysis A:

Ans:glycolysis

Q: The properties of the alkali metals are similar to each other as expected for elements in the same what? Read this paragraph and choose the correct option from the provided answers: The properties of the alkali metals are similar to each other as expected for elements in the same family. The alkali metals have the largest atomic radii and the lowest first ionization energy in their periods. This combination makes it very easy to remove the single electron in the outermost (valence) shell of each. The easy loss of this valence electron means that these metals readily form stable cations with a charge of 1+. Their reactivity increases with increasing atomic number due to the ease of losing the lone valence electron (decreasing ionization energy). Since oxidation is so easy, the reverse, reduction, is difficult, which explains why it is hard to isolate the elements. The solid alkali metals are very soft; lithium, shown in Figure 18.3, has the lowest density of any metal (0.5 g/cm3). The alkali metals all react vigorously with water to form hydrogen gas and a basic solution of the metal hydroxide. This means they are easier to oxidize than is hydrogen. As an example, the reaction of lithium with water is: 2Li(s) + 2H 2 O(l) 2LiOH(aq) + H 2(g). Choices: - class - branch - farm - family A:
family
