Answer:

Option A, occurs at a constant rate

Explanation:

It becomes easy to determine the age of any radioactive substance when the rate of decay is constant and its starting and presents mass is known.

For example - if we know that the mass of a radioactive substance is 100 Kg few years back , but its present mass is 10 Kg. Then if we know the value of rate of decay, we can easily determine the age of substance based on the logarithmic equation as given below

A_t= A_0*e^{kt}

Where A_t is the mass of radioactive substance at time t

A_0 is the mass of radioactive substance at time t=0

t is the time in years and

k is the decay constant.

Hence, option A is correct.

vichka [17]
The correct answer is resistance stage.

Hans Selye was a very important endocrinologist working in the field of biological stress. He developed the General Adaptation Syndrome (GAS) which is a model describing an animal's response to stress. GAS is comprised of three stages; the alarm, the resistance and the exhaustion stage.

During the resistance stage, the body's glands produce and secrete several hormones which protect the individual from the perceived stressor. Some of the hormones produced at this stage are the glucocorticoids.
