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.

Prokaryotes are the most primitive organism that exists on earth. They have the simplest form of body organization and they do not perform complex tasks.

The eukaryotic cell has nucleus in it and they have more complex machinery in their body to perform various tasks accordingly.

The nucleus of the prokaryotes are not enclosed in the nuclear membrane and it is dissolve in the cytoplasm. It lacks true nucleus.
