Persian windmill blades were vertical, like propellers,  while European ones were horizontal, like egg-beaters.

<u>Explanation: </u>

A windmill is a functioning engine sort of thing. This transforms energy from the wind into rotational energy. For this reason this requires vanes called sails or blades. The very first windmills featured with long vertical shafts with blades designed like rectangles who lived in ninth-century Persia.

Six to twelve sails were produced of those windmills. The sails had been coated with matting reed or fabric. They differed greatly from the European editions. In 13th century China a similar nature of vertical shaft windmill with rectangular blades was found used for irrigation. Overall around 60 AD vertical axle windmills had been found in eastern Persia. In the 1180s northwestern Europe developed horizontal axle windmills. It is the form that is often employed today.

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.
