Answer:
Enzymes function best at specific pH and temperatures.
Explanation:
An enzyme can be defined as a biological catalyst that typically lowers the activation energy of a biological reaction. When the activation energy of a reaction is low, the rate of the reaction would be faster. Therefore, an enzyme speeds or catalyzes the rate of a reaction by lowering its activation energy.
Also, if the conditions are not optimal for an enzyme, it limits the ability of an enzyme to bind or be joined with its substrates.
Hence, the correct statement about enzymes is that enzymes function best at specific pH and temperatures. An increase in temperature increases or speeds up the rate of a reaction while low temperature limits or reduces the rate of a reaction. The optimal temperature for enzymes in the human body is around 37 degrees celsius.
The correct option is C.
Both DNA and RNA are made up of four nitrogenous bases. The nitrogenous bases that are found in DNA are adenine, guanine, cytosine and thymine. The nitrogenous bases that are found in RNA are adenine, guanine, cytosine and uracil.
Answer:
Only one chromosome from each pair randomly passed to the s*x cells during meiosis and leads to differences between the siblings.
<span>The correct answer is C. The Fed lowers interest rates several months into a recession. It's a lag because they could've done it sooner and helped with the recession sooner but decided not to and thus they created a lag in monetary policy of a federation. It's like if the congress refused to help with the recession for no reason for a few months.</span>
