Why do you think weather scientists use percentages instead of saying “it will definitely rain today”?
grigory [225]

Answer:

Right now, I am in college for climatology, but before I decided on climatology, I was taking classes in Meteorology, the study of weather. So, I will answer your question. All meteorologists like to be right, but since the weather is so spontaneous, it is really hard to be right. Meteorologists use percentages because it helps them be professional. Also, because, different parts of the region where they are may or may not get the rain. I don't know where you are from, but I will use my hometown. In McAlester, Oklahoma, there may be a 70% chance of rain, but in another part of the region at Tulsa, Oklahoma ( which is 91 miles north of McAlester) there may be a 40% chance of rain. The difference in the percentages can vary from how stable the environment is, altitude, location, and terrain. That is two of the reasons why Meteorologists use percentages to predict weather.

Choose the CORRECT statement about enzymes below.
Papessa [141]

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.
