This is true. The nervous system produces chemicals that affect our body at a rapid pace and the effects are usually short term and are designed for situations that are out of the ordinary. The endocrine system works slower and in the long run and there's not that much rapid effect that happens in stressful situations that the endocrine system solves or resolves. The hormones produced by the endocrine system are a constant that keeps being produced and they balance our body functions.

N=N0e^-kt
N0 = initial amount of C-14 (at time t = 0)
N = amount of C-14 at time t
t = time, in years
k = 0.0001
N/N0 = e^-kt
we know N/N0 is 0.63
so we have:
0.63 = e^-kt
we can take the ln of both sides, leaving us with:
ln0.63 = -kt
t = ln0.63 / -(0.0001)
t = 4620 years
hope this helps with your thing!

There are no various sorts of bacterial provinces in Anna's example. Just Serratia marcescens was discovered in light of the fact that the microorganisms in the specimen all had a similar shape and size. Microbiologists need to detach bacterial provinces from an example to have the capacity to take a gander at what sorts of microscopic organisms are in the example.
