Reaction time is the length of time that passes between perceiving a problem and beginning to do something about it. Depending on the driver's physical and chemical state, it can vary from a fraction of a second to several seconds. Note that this has nothing to do with the skill of the driver, and does not imply that the action taken will necessarily be appropriate or properly executed.
The time marked 'X', is the second lag phase where the enzymes are setting up or changing to utilize the second or not preferred carbon source.
Delayed reaction time can hurt other parts of your body by not allowing you to move out of danger in time. For instance, a slow reaction may lead to you being stung by an insect.
Reaction time in the body comes from the brain and the nerves. The brain sends signals to the body which are carried by the nerves.

Yes, the reaction distances increases with speed while reaction time stays the same. for example the two-second rule.
The reaction time is the same whatever speed you are travelling at. It differs from one person to another but is approximately 0.1 second.
In absolute terms, no. If the reaction hasn't had any time to occur there is no reaction time to report.OTOH, you could say yes if the reaction time is
because when we know the setting time of cement we easily identified that where can we use the cement according to there setting time.
One fourths of a second....still pretty slow though :/
The time it takes for a reaction to occur is a function of the reaction rate constant and the amount of reactants. However, how long it takes for a reaction of occur completely depends on the type of reaction it is -- what the order of the reaction is. A first or second order reaction reaction will occur much faster earlier on, but slows down significantly once the reactants are depleted. The rate of a zero order reaction is constants regardless of the concentration of the reactants.
It varies from field to field. In computers, it refers to the amount of time (typically measures in milliseconds [1/1000th of a second), microseconds [1/1,000,000th of a second], nanoseconds [1/1,000,000,000th of a second] and sometimes picoseconds [1/1,000,000,000,000th of a second] For example, a 1 GHz CPU has a reaction time of 1/1,000,000,000th of a second, or 1 nanosecond, give or take based on various other influences. (A Hertz is a measurement of frequency per second. 1 Hz = once a second. 1kHz = 1,000 times a second, etc.)
No, it takes approximately three-quarters of a second for most humans to step on the brake from the time they recognize the need to do so. Some top atheletes can reduce the time to two-thirds of a second.
