Answer the following question given this paragraph: Latitude is the distance north or south of the Equator. It's measured in degrees, from 0 to 90. Several climate factors vary with latitude. Q: What is used to measure, in degrees, the distance north or south of the equater? Choices: - elevation - equator - magnitude - latitude A:
latitude

Answer the following question given this paragraph: Phospholipids As its name suggests, a phospholipid is a bond between the glycerol component of a lipid and a phosphorous molecule. In fact, phospholipids are similar in structure to triglycerides. However, instead of having three fatty acids, a phospholipid is generated from a diglyceride, a glycerol with just two fatty acid chains (Figure 2.23). The third binding site on the glycerol is taken up by the phosphate group, which in turn is attached to a polar "head" region of the molecule. Recall that triglycerides are nonpolar and hydrophobic. This still holds for the fatty acid portion of a phospholipid compound. However, the head of a phospholipid contains charges on the phosphate groups, as well as on the nitrogen atom. These charges make the phospholipid head hydrophilic. Therefore, phospholipids are said to have hydrophobic tails, containing the neutral fatty acids, and hydrophilic heads, containing the charged phosphate groups and nitrogen atom. Q: A phospholipid is a bond between the glycerol component of a lipid and what else? Choices: - chlorine molecule - elemental molecule - oxygen molecule - phosphorous molecule A:
(Answer)
phosphorous molecule
Ques: Answer the following question given this paragraph: A grain of pollen is a tiny male gametophyte enclosed in a tough capsule (see Figure below ). It carries sperm to an ovule while preventing it from drying out. Pollen grains can't swim, but they are very light, so the wind can carry them. Therefore, they can travel through air instead of water. Q: What can be described as a tiny male gametophyte enclosed in a tough capsule? Choices: - seed - cell - dna - grain of pollen A:
Ans: grain of pollen
(Q).

(A).
the operon
Ques:Answer the following question given this paragraph: The ions in ionic compounds are arranged in rigid three-dimensional patterns called crystal lattices. The crystal lattice that is formed is a characteristic property of a given compound. Q: The ions in ionic compounds are arranged in rigid three-dimensional patterns called what? Choices: - core lattices - lattice groups - pattern lattices - crystal lattices A:

Ans:crystal lattices
Question: Answer the following question given this paragraph: Q: What is the study of the vital statistics of populations and how they change over time? Choices: - sociology - ethnography - anthropology - demography A:
Answer:
demography
