Research the composition of blood and of urine. if you had to provide a recipe for making blood and for making urine, what would the ingredient lists look like? be as specific as possible. are there items in the blood that should not show up in urine?

Composition of urine: 95% water, 5% electrolytes and solutes.

Composition of blood: 55% plasma, 45% RBCs and <1% WBCs and platlets.

Blood cells and proteins are not present in urine.

Explanation:

Composition of urine: 95% water, 5% electrolytes and solutes. The solutes include end products of nitrogenous metabolites and substances from various drugs.  

Composition of blood: 55% plasma, 45% RBCs and <1% WBCs and platlets.

Urine does not contain the blood cells (RBCs, WBCs and platlets) and the protein. The blood cells and proteins are not filtered at glomerulus and hence, are not added to urine.

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.

looks like the answer is     c     to me!
