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:
protein fibers

Answer the following question given this paragraph: In addition to these organs, the male reproductive system consists of a series of ducts and glands. Ducts include the vas deferens and ejaculatory ducts. They transport sperm from the epididymis to the urethra in the penis. Glands include the seminal vesicles and prostate gland . They secrete substances that become part of semen. Q: The vas deferens and ejaculatory ducts are part of what system? Choices: - female adaptive system - female reproductive system - male circulatory system - male reproductive system A:
(Answer)
male reproductive system
Ques: Answer the following question given this paragraph: Q: Most of the gray matter is on the surface of the brain, surrounding what other type of matter? Choices: - blue - dark matter - corrugated - white A:
Ans: white
(Q).
Answer the following question given this paragraph: Shape of Proteins Just as a fork cannot be used to eat soup and a spoon cannot be used to spear meat, a protein's shape is essential to its function. A protein's shape is determined, most fundamentally, by the sequence of amino acids of which it is made (Figure 2.26a). The sequence is called the primary structure of the protein. Q: A protein's shape is determined, most fundamentally, by the sequence of what type of acids? Choices: - lipids - acetic - lactic - amino A:
(A).
amino
Ques:Answer the following question given this paragraph: 29.4 Reptiles The amniotes are distinguished from amphibians by the presence of a terrestrially adapted egg protected by amniotic membranes. The amniotes include reptiles, birds, and mammals. The early amniotes diverged into two main lines soon after the first amniotes arose. The initial split was into synapsids (mammals) and sauropsids. Sauropsids can be further divided into anapsids (turtles) and diapsids (birds and reptiles). Reptiles are tetrapods either having four limbs or descending from such. Limbless reptiles (snakes) are classified as tetrapods, as they are descended from four-limbed organisms. One of the key adaptations that permitted reptiles to live on land was the development of scaly skin containing the protein keratin, which prevented water loss from the skin. Reptilia includes four living clades: Crocodilia (crocodiles and alligators), Sphenodontia (tuataras), Squamata (lizards and snakes), and Testudines (turtles). Q: The amniotes are distinguished from amphibians by the presence of a terrestrially adapted egg protected by what? Choices: - hard shell - yolk - albumen - amniotic membranes A:

Ans:amniotic membranes
Ques:Answer the following question given this paragraph: Maps can often be used to measure distance. The map in the Figure below shows the route from Jordan's house to his school. You can use the scale at the bottom of the map to measure the distance between these two points. Q: What can often be used to measure distance? Choices: - histograms - models - graphs - maps A:

Ans:
maps
