Answer the following question given this paragraph: When using a microscope we do not see the entire extent of the sample. Depending on the eyepiece and objective lens we see a restricted region which we say is the field of view. The objective is then manipulated in two-dimensions above the sample to view other regions of the sample. Electronic scanning of either the objective or the sample is used in scanning microscopy. The image formed at each point during the scanning is combined using a computer to generate an image of a larger region of the sample at a selected magnification. When using a microscope, we rely on gathering light to form an image. Hence most specimens need to be illuminated, particularly at higher magnifications, when observing details that are so small that they reflect only small amounts of light. To make such objects easily visible, the intensity of light falling on them needs to be increased. Special illuminating systems called condensers are used for this purpose. The type of condenser that is suitable for an application depends on how the specimen is examined, whether by transmission, scattering or reflecting. See Figure 26.20 for an example of each. White light sources are common and lasers are often used. Laser light illumination tends to be quite intense and it is important to ensure that the light does not result in the degradation of the specimen. Q: When using a microscope we do not see the entire extent of the sample. depending on the eyepiece and objective lens we see a restricted region which we say is this? Choices: - tunnel vision - focal point - peripheral view - field of view A:
field of view
Q: Answer the following question given this paragraph: Cartilage: There are three cartilage types: 1. hyaline cartilage 2. fibrocartilage (fibrous cartilage) 3. elastic cartilage Hyaline cartilage: most widespread cartilage type, in adults forms articular surfaces of long bones, rib tips, rings of trachea, and parts of skull. Mostly collagen, name refers to glassy appearance. In embryo, bones form first as hyaline cartilage, later ossifies. Found in tracheal rings. Few collagen fibers. Fibrous cartilage: have lots of collagen fibers. Found in intervertebral discs, pubic symphesis. Grades into dense tendon and ligament tissue. Elastic cartilage: springy and elastic. Found in internal support of external ear and in epiglottis, yellow when fresh. Chondrocites (cartilage cells) rely on diffusion for nutrients, as cartilage has no direct blood supply, and no enervation (nerves). Can be loaded with calcium salts. Q: Comprised mainly of collagen and associated with long bones and the skull, hyaline is the most widespread type of what? Choices: - enzymes - tissue - cytoplasm - collagen A:
A: collagen
Question: Answer the following question given this paragraph: Cell division is relatively simple in prokaryotic cells. The two cells divide by binary fission. Green and orange lines indicate old and newly-generated bacterial cell walls, respectively. Eventually the parent cell will pinch apart to form two identical daughter cells. Left, growth at the center of bacterial body, such as in Bacillus subtilis and E. coli . Right, apical growth from the ends of the bacterial body, such as in Corynebacterium diphtheriae . Q: Eventually the parent cell will pinch apart to form two identical types of what cells? Choices: - brother cells - father cells - son cells - daughter cells A:
Answer: daughter cells

Answer the following question given this paragraph: Unlike corals, jellyfish spend most of their lives as medusae. They live virtually everywhere in the ocean. They are typically carnivores. They prey on zooplankton, other invertebrates, and the eggs and larvae of fish. Q: Unlike corals, jellyfish spend most of their lives as what? Choices: - infants - pupae - cercariae - medusae A:
**Answer**
medusae
