Answer: Option C.
Enzymes lowers activation energy required for a given reaction.
Explanation:
Enzymes are biological catalysts that are produced by living organisms which speed up the rate of chemical reaction.
Enzymes lower the activation energy of a given reactions. As the activation energy is lowered, the reaction becomes faster. Enzymes speed up the rate of reaction by lowering the activation energy.
Answer:
less dense than frozen water..
Explanation:
frozen h2o is heavier, weighs more...
A pH less than 7 is acidic. A pH greater than 7 is basic. The pH scale is logarithmic and as a result, each whole pH value below 7 is ten times more acidic than the next higher value. For example, pH 4 is ten times more acidic than pH 5 and 100 times (10 times 10) more acidic than pH 6.
The R-COOH. Unbranched hydrocarbon chain with carboxyl at one end.
Answer:
Agglutination test of antigen-antibody
Explanation:
Immunologic tests or methods are used to identify the presence of antibodies to a pathogen in the specimens of the patient.
Agglutination tests is an immunologic test used to identify the microbes in the specimens of the patient. In the agglutination test, a specimen such as red blood cells are taken which are then coated with antigen, if antibody forms clumps with antigen, it shows visible clumping of bacterial cells against the particular antibody.
Hence, the correct option is Agglutination test of antigen-antobody.
