Answer the following question given this paragraph: Curvatures of the Vertebral Column The adult vertebral column does not form a straight line, but instead has four curvatures along its length (see Figure 7.20). These curves increase the vertebral column's strength, flexibility, and ability to absorb shock. When the load on the spine is increased, by carrying a heavy backpack for example, the curvatures increase in depth (become more curved) to accommodate the extra weight. They then spring back when the weight is removed. The four adult curvatures are classified as either primary or secondary curvatures. Primary curves are retained from the original fetal curvature, while secondary curvatures develop after birth. Q: What feature of the spine helps with flexibility and strength? Choices: - shape - angle - arrangement - curves A:
curves

Answer the following question given this paragraph: Nuclear fission is the splitting of the nucleus of an atom into two smaller nuclei. This type of reaction releases a great deal of energy from a very small amount of matter. For example, nuclear fission of a tiny pellet of uranium-235, like the one pictured in Figure below , can release as much energy as burning 1,000 kilograms of coal!. Q: What do you call the splitting of the nucleus of an atom into two smaller nuclei? Choices: - critical fission - nuclear fusion - cell division - nuclear fission A:
(A).
nuclear fission

Ques:Answer the following question given this paragraph: Upwelling also takes place along the Equator. Winds blow the surface water north and south. This leaves a void that deep water can upwell into. The nutrients rise to the surface and support a great deal of life in the equatorial oceans. Q: Deep water filling a void caused by surface winds blowing water north and south is known as? Choices: - downwelling - surface current - divergence - upwelling A:

Ans:
upwelling
