Answer the following question given this paragraph: Something that is elastic can return to its original shape after being stretched or compressed. This property is called elasticity . As you stretch or compress an elastic material like a bungee cord, it resists the change in shape. It exerts a counter force in the opposite direction. This force is called elastic force . The farther the material is stretched or compressed, the greater the elastic force becomes. As soon as the stretching or compressing force is released, elastic force causes the material to spring back to its original shape. You can watch a demonstration of elastic force at this URL:. Q: What property means that something can return to its original shape after being stretched or compressed? Choices: - viscosity - homeostasis - friction - elasticity A:
elasticity
Answer the following question given this paragraph: Contour lines are lines of equal elevation. Contour intervals are the difference in elevation between two contour lines. Q: What is the term for the difference in elevation between two contour lines? Choices: - height - design interval - mapping interval - contour interval A:
contour interval
Q: Answer the following question given this paragraph: Hemoglobin Hemoglobin is a large molecule made up of proteins and iron. It consists of four folded chains of a protein called globin, designated alpha 1 and 2, and beta 1 and 2 (Figure 18.7a). Each of these globin molecules is bound to a red pigment molecule called heme, which contains an ion of iron (Fe2+) (Figure 18.7b). Q: Hemoglobin is a large molecule made up of proteins and iron. it consists of four folded chains of a protein called this? Choices: - peptide - histone - insulin - globin A:
A: globin
Question: Answer the following question given this paragraph: Homeostasis refers to the balance, or equilibrium within the cell or a body. It is an organism's ability to keep a constant internal environment. Keeping a stable internal environment requires constant adjustments as conditions change inside and outside the cell. The adjusting of systems within a cell is called homeostatic regulation. Because the internal and external environments of a cell are constantly changing, adjustments must be made continuously to stay at or near the set point (the normal level or range). Homeostasis is a dynamic equilibrium rather than an unchanging state. The cellular processes discussed in this lesson all play an important role in homeostatic regulation. More concerning homeostasis will be presented in additional concepts. Q: What is the name of the process that refers to the balance or equilibrium within the cell or a body? Choices: - static - hypothesis - determinants - homeostasis A:
Answer: homeostasis

Answer the following question given this paragraph: Springs like the ones in Figure below also have elastic force when they are stretched or compressed. And like stretchy materials, they return to their original shape when the stretching or compressing force is released. Because of these properties, springs are used in scales to measure weight. They also cushion the ride in a car and provide springy support beneath a mattress. Can you think of other uses of springs?. Q: What causes an elastic force in springs? Choices: - velocity - momentum - freezing - stretching or compressing A:
**Answer**
stretching or compressing

Answer the following question given this paragraph: Climate is found in zones around the planet. Warm tropical climates are mostly found near the Equator. Glaciers are mostly found nearer the poles. Wegener assumed that these things were true in the ancient past. Q: What type of climate is found mostly near the equator? Choices: - warm subtropical - hot dessert - cool tropical - warm tropical A:
(Answer)
warm tropical
