Answer: Half life
Explanation: Half life is the amount of time taken to reduce the original concentration of the reactant to half of its value.
Rate law expression for first order kinetics is given by:
where,
t= time taken for the decay
k = rate constant
t = time taken for decay process
a = initial amount of the reactant
a - x = amount left after decay process
for half life:
a-x =
The correct answer is:

I say b but I’m not sure
Answer: C
An operon is a function portion of a DNA strand that contains a cluster or genes that are controlled under one promoter. This is found in an bacteria or cell and controls protein synthesis. It helps conserve the energy of the cell by only producing proteins when necessary.
