Q: Answer the following question given this paragraph: 9.2 | DNA Replication By the end of this section, you will be able to: Explain the process of DNA replication Explain the importance of telomerase to DNA replication Describe mechanisms of DNA repair When a cell divides, it is important that each daughter cell receives an identical copy of the DNA. This is accomplished by the process of DNA replication. The replication of DNA occurs during the synthesis phase, or S phase, of the cell cycle, before the cell enters mitosis or meiosis. The elucidation of the structure of the double helix provided a hint as to how DNA is copied. Recall that adenine nucleotides pair with thymine nucleotides, and cytosine with guanine. This means that the two strands are complementary to each other. For example, a strand of DNA with a nucleotide sequence of AGTCATGA will have a complementary strand with the sequence TCAGTACT (Figure 9.8). Q: During which phase does dna replication occur in the cell cycle? Choices: - resting - gap - mitosis - synthesis A:
A: synthesis

Q: Answer the following question given this paragraph: Skin is made up of two layers, the epidermis and the dermis. Q: What are the two layers of the skin? Choices: - dermis and epithelial - sebaceous and salivary - epithelial and endometrial - epidermis and dermis A:
A: epidermis and dermis

Q: Answer the following question given this paragraph: An important concept in biology is that form follows function. In other words, the structure of an organism, or part of an organism, depends on its function. Apply this concept to plants, and explain why plants have different types of cells and tissues. Q: What concept can be applied to biology, because the structure of an organism, or part of an organism, depends on its function? Choices: - motion follows function - attachment follows function - form follows use - form follows function A:
A: form follows function

Q: Answer the following question given this paragraph: 4.3 | Connective Tissue Supports and Protects By the end of this section, you will be able to: Identify and distinguish between the types of connective tissue: proper, supportive, and fluid Explain the functions of connective tissues As may be obvious from its name, one of the major functions of connective tissue is to connect tissues and organs. Unlike epithelial tissue, which is composed of cells closely packed with little or no extracellular space in between, connective tissue cells are dispersed in a matrix. The matrix usually includes a large amount of extracellular material produced by the connective tissue cells that are embedded within it. The matrix plays a major role in the functioning of this tissue. The major component of the matrix is a ground substance often crisscrossed by protein fibers. This ground substance is usually a fluid, but it can also be mineralized and solid, as in bones. Connective tissues come in a vast variety of forms, yet they typically have in common three characteristic components: cells, large amounts of amorphous ground substance, and protein fibers. The amount and structure of each component correlates with the function of the tissue, from the rigid ground substance in bones supporting the body to the inclusion of specialized cells; for example, a phagocytic cell that engulfs pathogens and also rids tissue of cellular debris. Q: Connective tissues typically have three characteristic components in common: cells, large amounts of amorphous ground substance, and what else? Choices: - antioxidants - hormones - white blood cells - protein fibers A:
A: protein fibers
