Answer the following question given this paragraph: To predict the relative stabilities of metal complexes with different ligands. One of the most important properties of metallic elements is their ability to act as Lewis acids that form complexes with a variety of Lewis bases. A metal complex consists of a central metal atom or ion that is bonded to one or more ligands (from the Latinligare, meaning "to bind"), which are ions or molecules that contain one or more pairs of electrons that can be shared with the metal. Metal complexes can be neutral, such as Co(NH3)3Cl3; positively charged, such as [Nd(H2O)9]3+; or negatively charged, such as [UF8]4. Electrically charged metal complexes are sometimes called complex ions. A coordination compound contains one or more metal complexes. Coordination compounds are important for at least three reasons. First, most of the elements in the periodic table are metals, and almost all metals form complexes, so metal complexes are a feature of the chemistry of more than half the elements. Second, many industrial catalysts are metal complexes, and such catalysts are steadily becoming more important as a way to control reactivity. For example, a mixture of a titanium complex and an organometallic compound of aluminum is the catalyst used to produce most of the polyethylene and polypropylene "plastic" items we use every day. Finally, transition-metal complexes are essential in biochemistry. Examples include hemoglobin, an iron complex that transports oxygen in our blood; cytochromes, iron complexes that transfer electrons in our cells; and complexes of Fe, Zn, Cu, and Mo that are crucial components of certain enzymes, the catalysts for all biological reactions. Metal complexes are so important in biology that we consider the topic separately in Section 23.6 "Transition Metals in Biology". Q: Hemoglobin is responsible for transporting what within our blood? A:
OPTIONS:
- water
- nitrogen
- dioxide
- oxygen
oxygen

Answer the following question given this paragraph: Flatworms do not have a respiratory system. Instead, they have pores that allow oxygen to enter through their body. Oxygen enters the pores by diffusion. Q: By what process does oxygen enter the pores of flatworms? A:
OPTIONS:
- absorption
- filtration
- permeation
- diffusion

Answer: diffusion

Question: Answer the following question given this paragraph: Q: Composed largely of the polysaccharide chitin, the exoskeleton provides an effective barrier defense against most what? A:
OPTIONS:
- parasites
- white blood cells
- vaccines
- pathogens
Answer: pathogens

input with options: Answer the following question given this paragraph: A: Both boxes have the same volume because they are the same size. However, the books have greater mass than the feathers. Therefore, the box of books has greater density. Q: What third property is different if two boxes have the same volume but one has greater mass? A:
OPTIONS:
- oxygen
- output
- diameter
- density
output: density

Problem: OPTIONS:
- color
- mass
- weight
- steepness
Q: Answer the following question given this paragraph: A: Variables might include factors relating to the ramp or to the object. An example of a variable relating to the ramp is its steepness. An example of a variable relating to the object is the way it movesit might roll or slide down the ramp. Either of these variables could be manipulated by the researcher, so you could choose one of them for your manipulated variable. Q: An example of a variable relating to the ramp is its what? A:
Answer:
steepness
