Some glands affect multiple functions in the body, and other glands are more specialized. consider these endocrine glands: adrenals, liver, pancreas, pituitary, salivary, and thyroid. the table categorizes these glands according to the functions they regulate. (functions are listed in the top row.) which labels should replace the numbers to correctly complete the table? 1 digestion 3 growth adrenals pancreas pituitary 4 pituitary salivary adrenals pancreas 2 number 1 is behavior, 2 is pituitary, 3 is metabolism, and 4 is thyroid. number 1 is behavior, 2 is thyroid, 3 is metabolism, and 4 is pancreas. number 1 is metabolism, 2 is adrenals, 3 is behavior, and 4 is liver. number 1 is metabolism, 2 is liver, 3 is behavior, and 4 is pituitary.

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
