Q: The number of moles of solute in 1 kg of solvent is defined as what? Read this paragraph and choose the correct option from the provided answers: An alternative way to define the concentration of a solution is molality, abbreviated m. Molality is defined as the number of moles of solute in 1 kg of solvent. How is this different from molarity? Would you expect a 1 M solution of sucrose to be more or less concentrated than a 1 m solution of sucrose? Explain your answer. What are the advantages of using solutions for quantitative calculations?. Choices: - singularity - pollenation - kilocalorie - molarity A:
molarity

Ques: Q: Like sharks, nearly the entire human skeleton during a specific pre-birth developmental stage is made of what connective tissue? Read this paragraph and choose the correct option from the provided answers: Cartilage Cartilage is a connective tissue with a large amount of the matrix and variable amounts of fibers. The cells, called chondrocytes, make the matrix and fibers of the tissue. Chondrocytes are found in spaces within the tissue called lacunae. A cartilage with few collagen and elastic fibers is hyaline cartilage, illustrated in Figure 33.14. The lacunae are randomly scattered throughout the tissue and the matrix takes on a milky or scrubbed appearance with routine histological stains. Sharks have cartilaginous skeletons, as does nearly the entire human skeleton during a specific pre-birth developmental stage. A remnant of this cartilage persists in the outer portion of the human nose. Hyaline cartilage is also found at the ends of long bones, reducing friction and cushioning the articulations of these bones. Choices: - chloroplasm - phloem - collagen - cartilage A:
Ans: cartilage
