Answer the following question given this paragraph: Electron Microscopes In contrast to light microscopes, electron microscopes use a beam of electrons instead of a beam of light. Not only does this allow for higher magnification and, thus, more detail (Figure 3.3), it also provides higher resolving power. Preparation of a specimen for viewing under an electron microscope will kill it; therefore, live cells cannot be viewed using this type of microscopy. In addition, the electron beam moves best in a vacuum, making it impossible to view living materials. In a scanning electron microscope, a beam of electrons moves back and forth across a cell's surface, rendering the details of cell surface characteristics by reflection. Cells and other structures are usually coated with a metal like gold. In a transmission electron microscope, the electron beam is transmitted through the cell and provides details of a cell's internal structures. As you might imagine, electron microscopes are significantly more bulky and expensive than are light microscopes. Q: What powerful microscopes use a beam of subatomic particles instead of a beam of light? A:

OPTIONS:
- complex microscopes
- scientific microscopes
- nuclear microscopes
- electron microscopes

Answer: electron microscopes

Answer the following question given this paragraph: Q: The fact that water in a reservoir is elevated above the ground means that it has what kind of energy? A:

OPTIONS:
- excessive
- nuclear
- kinetic
- potential

Answer: potential

Answer the following question given this paragraph: inner aspect of the atlas, where it is held in place by a ligament. Rotation at this joint allows you to turn your head from side to side. A second pivot joint is found at the proximal radioulnar joint. Here, the head of the radius is largely encircled by a ligament that holds it in place as it articulates with the radial notch of the ulna. Rotation of the radius allows for forearm movements. Q: Which common type of diabetes is also known as noninsulin-dependent or adult-onset diabetes? A:

OPTIONS:
- type 1
- gestational diabetes
- juvenile diabetes
- type 2

Answer: type 2

Answer the following question given this paragraph: CHAPTER REVIEW 4.1 Types of Tissues The human body contains more than 200 types of cells that can all be classified into four types of tissues: epithelial, connective, muscle, and nervous. Epithelial tissues act as coverings controlling the movement of materials across the surface. Connective tissue integrates the various parts of the body and provides support and protection to organs. Muscle tissue allows the body to move. Nervous tissues propagate information. The study of the shape and arrangement of cells in tissue is called histology. All cells and tissues in the body derive from three germ layers in the embryo: the ectoderm, mesoderm, and endoderm. Different types of tissues form membranes that enclose organs, provide a friction-free interaction between organs, and keep organs together. Synovial membranes are connective tissue membranes that protect and line the joints. Epithelial membranes are formed from epithelial tissue attached to a layer of connective tissue. There are three types of epithelial membranes: mucous, which contain glands; serous, which secrete fluid; and cutaneous which makes up the skin. Q: What science is the study of the shape and arrangement of cells in tissue? A:

OPTIONS:
- methodology
- cellology
- genetics
- histology

Answer:
histology
