The advantageous proteins that build larger molecules help prolong life life. If there is better survival and reproduction, it is more likely to pass onto the next generation. If it continues to be advantageous, the sequence of them change to support the life of the current species.
Answer:
The half-life (t1/2) is the time taken for the activity of a given amount of a radioactive substance to decay to half of its initial value. The mean lifetime (τ, “tau”) is the average lifetime of a radioactive particle before decay. The decay constant (λ, “lambda”) is the inverse of the mean lifetime
