Ques:Answer the following question given this paragraph: Hormonal Regulation of Metabolism Catabolic and anabolic hormones in the body help regulate metabolic processes. Catabolic hormones stimulate the breakdown of molecules and the production of energy. These include cortisol, glucagon, adrenaline/epinephrine, and cytokines. All of these hormones are mobilized at specific times to meet the needs of the body. Anabolic hormones are required for the synthesis of molecules and include growth hormone, insulin-like growth factor, insulin, testosterone, and estrogen. Table 24.1 summarizes the function of each of the catabolic hormones and Table 24.2 summarizes the functions of the anabolic hormones. Q: Catabolic and anabolic hormones in the body help regulate these? Choices: - brain signals - hormone levels - nutrient levels - metabolic processes A:

Ans:metabolic processes

Ques:Answer the following question given this paragraph: The majority of solids are crystalline in nature. A crystal is a substance in which the particles are arranged in an orderly, repeating, three-dimensional pattern. Particles of a solid crystal may be ions, atoms, or molecules, depending on the type of substance. The three-dimensional arrangement of a solid crystal is referred to as the crystal lattice . Different arrangements of the particles within a crystal cause them to adopt several different shapes. Q: The majority of solids are what in nature? Choices: - gases - complex - liquids - crystalline A:

Ans:
crystalline
