Problem: OPTIONS:
- thallus
- manubrium
- cortex
- cerebrum
Q: Answer the following question given this paragraph: In intelligent mammals, such as primates, the cerebrum is larger compared to the rest of the brain. A larger cerebrum allows primates to develop higher levels of intelligence. Primates have the ability to learn new behaviors. They also engage in complex social interactions, such as fighting and play. Q: What part of the brain is largest in intelligent mammals? A:
Answer: cerebrum

Problem:OPTIONS:
- it fluctuates
- it increases
- it stabilizes
- it gets lower

Answer the following question given this paragraph: At higher latitudes, the Sun's rays are less direct. The farther an area is from the Equator, the lower its temperature. Q: The farther an area is from the equator, what happens to the temperature? A:
****
A: it gets lower

Answer the following question given this paragraph: The carbon monoxide molecule is correctly represented by a triple covalent bond between the carbon and oxygen atoms. One of the bonds is a coordinate covalent bond , a covalent bond in which one of the atoms contributes both of the electrons in the shared pair. Q: In what kind of bond does one atom contribute both of the electrons in the shared pair? A:
OPTIONS:
- a valence bond
- a metallic bond
- an ionic bond
- a covalent bond
a covalent bond

Answer the following question given this paragraph: Pipettes are small, but important tools in many biology labs. Micropipettes, such as the ones shown here, are calibrated to measure very small amounts of liquids. For example, 100 microliters (100 L) is about half the volume of your little finger tip; or even 1 L, which is much smaller than a drop of water. Q: What kind of pipettes are suitable for measuring very small amounts of liquids? A:
OPTIONS:
- clutch pipettes
- macropipettes
- frozen pipettes
- micropipettes

Answer: micropipettes

Question: Answer the following question given this paragraph: A whole molecule may also have a separation of charge, depending on its molecular structure and the polarity of each of its bonds. If such a charge separation exists, the molecule is said to be a polar molecule (or dipole); otherwise the molecule is said to be nonpolar. The dipole moment measures the extent of net charge separation in the molecule as a whole. We determine the dipole moment by adding the bond moments in three-dimensional space, taking into account the molecular structure. For diatomic molecules, there is only one bond, so its bond dipole moment determines the molecular polarity. Homonuclear diatomic molecules such as Br2 and N2 have no difference in electronegativity, so their dipole moment is zero. For heteronuclear molecules such as CO, there is a small dipole moment. For HF, there is a larger dipole moment because there is a larger difference in electronegativity. When a molecule contains more than one bond, the geometry must be taken into account. If the bonds in a molecule are arranged such that their bond moments cancel (vector sum equals zero), then the molecule is nonpolar. This is the situation in CO2 (Figure 7.27). Each of the bonds is polar, but the molecule as a whole is nonpolar. From the Lewis structure, and using VSEPR theory, we determine that the CO2 molecule is linear with polar C=O bonds on opposite sides of the carbon atom. The bond moments cancel because they are pointed in opposite directions. In the case of the water molecule (Figure 7.27), the Lewis structure again shows that there are two bonds to a central atom, and the electronegativity difference again shows that each of these bonds has a nonzero bond moment. In this case, however,. Q: Why do homonuclear diatomic molecules have zero dipole moment? A:
OPTIONS:
- no electrical attraction
- no activation energy
- at homeostasis
- no difference in electronegativity
Answer: no difference in electronegativity

input: OPTIONS:
- air
- trees
- land
- ocean Now, answer this question: Answer the following question given this paragraph: Mollusks live in most terrestrial, freshwater, and marine habitats. However, the majority of species live in the ocean. They can be found in both shallow and deep water and from tropical to polar latitudes. They have a variety of ways of getting food. Some are free-living heterotrophs. Others are internal parasites. Mollusks are also eaten by many other organisms, including humans. Q: Where do the majority of species live? A:
A:
output:
ocean
