Answer the following question given this paragraph: Earth's magnetic poles have switched places repeatedly in the past. As you can see in the Figure below , each time the switch occurred, Earth's magnetic field was reversed. The magnetic field is the region around a magnet over which it exerts magnetic force. We think of today's magnetic field direction as "normal," but that's only because it's what we're used to. You can watch a simulation of a magnetic field reversal at this URL: http://www. pbs. org/wgbh/nova/earth/when-our-magnetic-field-flips. html. Q: The earth's magnetic poles have done what repeatedly in the past? Choices: - rotated - stayed the same - demagnetized - switched places A:
(Answer)
switched places

Answer the following question given this paragraph: Intrinsic Pathway The intrinsic pathway (also known as the contact activation pathway) is longer and more complex. In this case, the factors involved are intrinsic to (present within) the bloodstream. The pathway can be prompted by damage to the tissues, resulting from internal factors such as arterial disease; however, it is most often initiated when factor XII (Hageman factor) comes into contact with foreign materials, such as when a blood sample is put into a glass test tube. Within the body, factor XII is typically activated when it encounters negatively charged molecules, such as inorganic polymers and phosphate produced earlier in the series of intrinsic pathway reactions. Factor XII sets off a series of reactions that in turn activates factor XI (antihemolytic factor C or plasma thromboplastin antecedent) then factor IX (antihemolytic factor B or plasma thromboplasmin). In the meantime, chemicals released by the platelets increase the rate of these activation reactions. Finally, factor VIII (antihemolytic factor A) from the platelets and endothelial cells combines with factor IX (antihemolytic factor B or plasma thromboplasmin) to form an enzyme complex that activates factor X (StuartPrower factor or thrombokinase), leading to the common pathway. The events in the intrinsic pathway are completed in a few minutes. Q: What term is also known as the contact activation pathway? Choices: - central pathway - internal pathway - identical pathway - intrinsic pathway A:
(A).
intrinsic pathway
Ques:Answer the following question given this paragraph: Figure below shows those distances correctly. In the upper left are the orbits of the inner planets and the asteroid belt. The asteroid belt is a collection of many small objects between the orbits of Mars and Jupiter. In the upper right are the orbits of the outer planets and the Kuiper belt. The Kuiper belt is a group of objects beyond the orbit of Neptune. Q: Which planet is the kuiper belt closest to? Choices: - Mars - Jupiter - Venus - neptune A:

Ans:neptune
Answer the following question given this paragraph: Soil scientists measure the percentage of sand, silt, and clay in soil. They plot this information on a triangular diagram, with each type of particle at one corner ( Figure below ). Q: What kind of scientists measure percentages of sand, silt, and clay? Choices: - texture scientists - amount scientists - petro scientists - soil scientists A:
soil scientists
