lab, we used Benedict's reagent to test for one particular reducing sugar: glucose. Benedict's reagent starts out aqua-blue. As it is heated in the presence of reducing sugars, it turns yellow to orange. The "hotter" the final color of the reagent, the higher the concentration of reducing sugar.
Answer: pressure is called atmospheric pressure, or air pressure. It is the force exerted on a surface by the air above it as gravity pulls it to Earth. Atmospheric pressure is commonly measured with a barometer. ... Meteorologists describe the atmospheric pressure by how high the mercury rises.
Explanation: i hope this helps you. i learned this last year :)

he use the shadows of the earth to see its round shape
Animals don’t need to absorb sunlight in order to live. Only plants have chloroplasts to absorb the rays from the sun which is required for them to live and grow
Chymotrypsin is permanently inhibited by TPCK. Additionally inhibits certain cysteine proteases, including ficin, papain, caspase, and bromelain. For the chemical labeling of active histidine in enzyme analysis, TPCK is chosen. Because the enzyme has a preference for aromatic amino acid residues at the active site, the phenylalanine moiety is attached to the enzyme (as in chymotrypsin, in which it binds to the Histidine-57 residue in the active site).
[1] Neither zymogens nor trypsin are inhibited by it.
In the crystal structure of the complex solved in 2010, TPCK is seen covalently bonded in the active site of Caspase 3.
[2] With the chlorine removed, the chloromethyl group interacts with the cysteine in the active site to form a covalent connection.
