Q: Answer the following question given this paragraph: Plasma Anticoagulants An anticoagulant is any substance that opposes coagulation. Several circulating plasma anticoagulants play a role in limiting the coagulation process to the region of injury and restoring a normal, clot-free condition of blood. For instance, a cluster of proteins collectively referred to as the protein C system inactivates clotting factors involved in the intrinsic pathway. TFPI (tissue factor pathway inhibitor) inhibits the conversion of the inactive factor VII to the active form in the extrinsic pathway. Antithrombin inactivates factor X and opposes the conversion of prothrombin (factor II) to thrombin in the common pathway. And as noted earlier, basophils release heparin, a short-acting anticoagulant that also opposes prothrombin. Heparin is also found on the surfaces of cells lining the blood vessels. A pharmaceutical form of heparin is often administered therapeutically, for example, in surgical patients at risk for blood clots. Q: What do you call any substance that opposes coagulation? A:

OPTIONS:
- dissolvent
- antibodies
- toxin
- anticoagulant

A: anticoagulant

Answer the following question given this paragraph: Only the top 200 meters or so of water receive enough sunlight for photosynthesis. This part of the water is called the photic zone. Below 200 meters, there is too little sunlight for photosynthesis to take place. This part of the water is called the aphotic zone. In this zone, food must come from other sources. It may be made by chemosynthesis, in which microorganisms use energy in chemicals instead of sunlight to make food. Or, food may drift down from the water above. Q: What is the top part of water able to receive enough sunlight for photosynthesis called? A:

OPTIONS:
- thymic zone
- synthesis zone
- fantasmic zone
- photic zone

Answer: photic zone

Problem: OPTIONS:
- work
- energy
- speed
- time
Q: Answer the following question given this paragraph: Electrical energy consumed can be determined by multiplying power by time . Recall the equations for mechanical and thermal energy/work . An important idea is the efficiency of an electrical device: the fraction of electrical energy consumed that goes into doing useful work , expressed as a percentage. Q: Electrical energy consumed can be expressed as the product of power multiplied by what else? A:
Answer: time

Problem:OPTIONS:
- neutralization
- acceleration
- homeostasis
- equilibrium

Answer the following question given this paragraph: Imagine you are stranded in a rowboat in the middle of the ocean. Suddenly, your boat springs a small leak, and you need to bail out water. You grab a bucket and begin to bail. After a few minutes, your efforts against the leak keep the water to only about half an inch, but any further bailing doesn't change the water level; the leak brings in as much water as you bail out. You are at equilibrium. Two opposing processes have reached the same speed, and there is no more overall change in the process. Chemical reactions are like that as well. Most of them come to an equilibrium. The actual position of the equilibriumwhether it favors the reactants or the productsis characteristic of a chemical reaction; it is difficult to see just by looking at the balanced chemical equation. But chemistry has tools to help you understand the equilibrium of chemical reactionsthe focus of our study in this chapter. So far in this text, when we present a chemical reaction, we have implicitly assumed that the reaction goes to completion. Indeed, our stoichiometric calculations were based on this; when we asked how much of a product is produced when so much of a reactant reacts, we are assuming that all of a reactant reacts. However, this is usually not the case; many reactions do not go to completion, and many chemists have to deal with that. In this chapter, we will study this phenomenon and see ways in which we can affect the extent of chemical reactions. Q: What is the term for when two opposing processes reach the same speed, resulting in no overall change? A:
****
A: equilibrium

Problem:OPTIONS:
- patterns
- spheres
- groups
- squares

The square contains the chemical symbol for the element, the atomic number, and the atomic weight . The atomic weight of an element is a weighted average of its isotopes. Q: The periodic table of elements is divided into what? A:
****
A:
squares
