Answer:
For example, an atom with 6 of 8 electrons in its outer shell will try to gain 2 electrons so its outer shell is full. Ionic bonding occurs when one element donates an electron (or electrons) to another so that both elements will have a full outer shell. As the attractions bring the atoms together, electrons from each atom are attracted to the nucleus of both atoms, which “share” the electrons. The sharing of electrons between atoms is called a covalent bond, which holds the atoms together as a molecule.

Answer: In part (A), Pgas>Patm, as evidenced by the column of mercury being "pushed up" in the manometer on the side of Patm - in this case, you'll need to add (the amount it's "pushed up") to atmospheric pressure (i.e., 764 mm Hg). You state that you tried to subtract 40.0 from 764.0: Look at the graphic again (I hold it's 7 cm - or 70 mm - Hg) and try adding that number to 764 mm Hg instead of 40 mm Hg.

Answer:
A drug treatment that reduces the risk of relapse to 0
Answer:
The answer to this question lies in the number of steps, and substances, that are needed in order to yield ATP from ADP. While in anaerobic glycolysis pyruvic acid and lactic acid will yield their energy so that ADP can be re-synthetized into ATP, producing 2 molecules of ATP from that simple chain of reaction, aerobic glycolysis depends on the presence of oxygen, and several more chemical steps, chemical reactions, in order to finally yield all the ATPs it can yield.
Explanation:
When we are talking about intense training, like a sudden sprint, we are talking about the body needing ATP as fast as it possibly can get it so the muscles can move. Because of this immediacy, the body resorts first to its stores in muscle tissue and in the liver, to feed the anaerobic processes for ATP formation. The other process, called the Lactic Acid system, is the second of the anaerobic processes and its benefit is that while not requiring oxygen to produce ATP, it will use the stores of glycogen in the muscle and the liver, and through the chemical reactions of enzymes, it will produce enough ATP to power the exercise for at least a few minutes, without having to resort to the aerobic system. The number of steps taken to yield ATP are much lesser, and thus much more immediate, than in aerobic glycolysis.
Answer: d. Confounding
Explanation:
In the context of a scientific study such as this one, a confounding factor is one that has influence on both the exposure and event variable(s), which may lead to over- or underestimation of the direct relationship between them (if any).
For instance: In this example, researchers may have had reason to believe that male gender is associated with both higher risk of obesity (the exposure variable) and adult-onset asthma (the event variable). If gender is not taken into account, one may claim that the finding of an association between obesity and asthma is simply an artifact due to the high proportion of male patients (likely to present with both). <em>Controlling</em> for that variable (such as by matching, as in this example) allows researchers to test for this hypothesis.
