Ques: Answer the following question given this paragraph: Immovable joints allow no movement because the bones at these joints are held securely together by dense collagen. The bones of the skull are connected by immovable joints. Q: The bones of the skull are connected by what type of joints? Choices: - semi-mobile - pivoting - adjustable - immovable A:
Ans: immovable

Ques: Answer the following question given this paragraph: A unit cell is the smallest portion of a crystal lattice that shows the three-dimensional pattern of the entire crystal. A crystal can be thought of as the same unit cell repeated over and over in three dimensions. The Figure below illustrates the relationship of a unit cell to the entire crystal lattice. Q: What is the smallest portion of a crystal lattice? Choices: - ionic cell - function cell - element cell - unit cell A:
Ans: unit cell

Ques: Answer the following question given this paragraph: hydrophilic heads are directed outward, in contact with the water. Each micelle may contain thousands of lipid molecules. Polar lipids may also form a monolayer, a layer one molecule thick on the surface of the water. The polar heads face into water, and the nonpolar tails stick up into the air. Bilayers are double layers of lipids arranged so that the hydrophobic tails are sandwiched between an inner surface and an outer surface consisting of hydrophilic heads. The hydrophilic heads are in contact with water on either side of the bilayer, whereas the tails, sequestered inside the bilayer, are prevented from having contact with the water. Bilayers like this make up every cell membrane (Figure 17.6 "Schematic Diagram of a Cell Membrane"). Figure 17.5 Spontaneously Formed Polar Lipid Structures in Water: Monolayer, Micelle, and Bilayer. Q: When something is described as "hydrophilic", you can determine something about how it interacts with what? Choices: - hydrogen - air - iron - water A:
Ans: water

Ques: Answer the following question given this paragraph: The water cycle includes the ocean, atmosphere, ground, and living things. During the water cycle, water keeps changing state by processes such as evaporation, transpiration, condensation, and precipitation. Q: Precipitation, evaporation, transpiration, and condensation are part of what cycle? Choices: - life cycle - air cycle - cold cycle - water cycle A:
Ans:
water cycle
