Ques:Q: The afferent arterioles service about 1.3 million of what in each kidney? Read this paragraph and choose the correct option from the provided answers: Nephrons and Vessels The renal artery first divides into segmental arteries, followed by further branching to form interlobar arteries that pass through the renal columns to reach the cortex (Figure 25.9). The interlobar arteries, in turn, branch into arcuate arteries, cortical radiate arteries, and then into afferent arterioles. The afferent arterioles service about 1.3 million nephrons in each kidney. Choices: - dendrites - axons - neurons - nephrons A:

Ans:nephrons

Ques:Q: Ionic, molecular, covalent, and metallic are major types of what state of matter? Read this paragraph and choose the correct option from the provided answers: Summary The major types of solids are ionic, molecular, covalent, and metallic. Ionic solids consist of positively and negatively charged ions held together by electrostatic forces; the strength of the bonding is reflected in the lattice energy. Ionic solids tend to have high melting points and are rather hard. Molecular solids are held together by relatively weak forces, such as dipoledipole interactions, hydrogen bonds, and London dispersion forces. As a result, they tend to be rather soft and have low melting points, which depend on their molecular structure. Covalent solids consist of two- or three-dimensional networks of Saylor URL: http://www. saylor. org/books. Choices: - gas - liquid - plasma - solids A:
