Answer the following question given this paragraph: The retina is a membrane lining the back of the eye. The retina has nerve cells called rods and cones that change images to electrical signals. Rods are good at sensing dim light but can't distinguish different colors of light. Cones can sense colors but not dim light. There are three different types of cones. Each type senses one of the three primary colors of light (red, green, or blue). Q: What do you call the membrane lining the back of the eye? A:
OPTIONS:
- cornea
- stimulation
- aperture
- retina
retina

Answer the following question given this paragraph: 22.3 Magnetic Fields and Magnetic Field Lines Magnetic fields can be pictorially represented by magnetic field lines, the properties of which are as follows: 1. The field is tangent to the magnetic field line. Field strength is proportional to the line density. Field lines cannot cross. Field lines are continuous loops. Q: An infection may be intracellular or extracellular, depending on this? A:
OPTIONS:
- pollen
- microbes
- bacteria
- pathogen

Answer: pathogen

Question: Answer the following question given this paragraph: Water is an amazing molecule. It has a very simple chemical formula, H 2 O. It is made of just two hydrogen atoms bonded to one oxygen atom. Water is remarkable in terms of all the things it can do. Lots of things dissolve easily in water. Some types of rock can even completely dissolve in water! Other minerals change by adding water into their structure. Q: What is the common term for the chemical formula h 2 0? A:
OPTIONS:
- hydrogen
- air
- oxygen
- water
Answer: water

input with options: Answer the following question given this paragraph: Reactions and Compounds of Nitrogen Like carbon, nitrogen has four valence orbitals (one 2s and three 2p), so it can participate in at most four electron-pair bonds by using sp3 hybrid orbitals. Unlike carbon, however, nitrogen does not form long chains because of repulsive interactions between lone pairs of electrons on adjacent atoms. These interactions become important at the shorter internuclear distances encountered with the smaller, second-period elements of groups 15, 16, and 17. (For more information on internuclear distance, see Chapter 7 "The Periodic Table and Periodic Trends", Section 7.2 "Sizes of Atoms and Ions" and Chapter 8 "Ionic versus Covalent Bonding", Section 8.2 "Ionic Bonding". ) Stable compounds with NN bonds are limited to chains of no more than three N atoms, such as the azide ion (N 3). Nitrogen is the only pnicogen that normally forms multiple bonds with itself and other second-period elements, using overlap of adjacent np orbitals. Thus the stable form of elemental nitrogen is N 2, whose NN bond is so strong (DNN = 942 kJ/mol) compared with the NN and N=N bonds (DNN = 167 kJ/mol; DN=N = 418 kJ/mol) that all compounds containing NN and N=N bonds are thermodynamically unstable with respect to the formation of N2. In fact, the formation of the NN bond is so thermodynamically favored that virtually all compounds containing NN bonds are potentially explosive. Again in contrast to carbon, nitrogen undergoes only two important chemical reactions at room temperature: it reacts with metallic lithium to form lithium nitride, and it is reduced to ammonia by certain microorganisms. (For more information lithium, seeChapter 21 "Periodic Trends and the ". ) At higher temperatures, however, N2 reacts with more electropositive elements, such as those in group 13, to give binary nitrides, which range from covalent to ionic in character. Like the corresponding compounds of carbon, binary compounds of nitrogen with oxygen, hydrogen, or other nonmetals are usually covalent molecular...
