Answer:
0.00004524 minute
Explanation:
The enzyme is Catalase, and it speeds up the rate of reaction by 700 times than what it was supposed to be.
If the already sped up rate of reaction is 1.9 seconds, then the initial reaction ought to have taken
1.9/700 seconds and that is 0.0027143 second.
We're asked to convert to minute, we then have
0.0027143/60 which is equal to 0.0000452381 minute.
Since we're asked to round off to 4 significant figure, we have 0.00004524 minute.
Answer:
The answer is "frequency with which they are activated".
Explanation:
Frequency refers to the number of consecutive repetitive events per unit time. It is measured in hertz (Hz), equivalent to a single event per second. The time is the number of one cycle in a recurrent event, and so the duration is the same for the frequency, hence the frequency at which they are triggered is a key determinant of the brain's connections to be eliminated and maintained.
If you don't have much of a reason it's just because you're a teenager, that's one of the symptoms :)
(really though, scientifically)

It is a spongy structure, filled with blood vessels that come from the mother by way of the lining of the uterus, and then connects with the baby by the umbilical cord
