Answer:
This is due to bio magnification.
Explanation:
When there is a gradual increase in concentration toxins(pesticides) in the tissues of organisms progressively in the food chain,the term for describing this is called -bio magnification.
The progressive multiplication in the concentration of these toxins may be due to non-biodegradable nature of the toxins,which are absorbed into the tissues of mostly the producers from the environment faster than they could metabolized by the body.
.Therefore these could not be removed by the producers, during excretion and respiration,and hence build up progressively upwards in the consumers.
A typical example is the phytoplankton which absorb toxins from sea water and accumulate this in the body.The build could not be ,metabolize by the body system,and is transferred to the zooplankton along the food chains when they feed on the phytoplanktons- this is Bio magnification.

By repeating an experiment many times, scientists increase confidence in the results. So, the correct option is (A).
What is an experiment?An experiment is defined as a procedure which is carried out to support or disprove a hypothesis. It determines the efficacy or potential of something previously unusable. It provides insight into cause and effect by demonstrating what results when a particular factor is manipulated.
An experiment is defined as a type of empirical study that involves manipulation of an independent variable, measurement of a dependent variable, and control of extraneous variables. This extraneous variable is any variable other than the independent and dependent variables.
The best approach when conducting a scientific experiment is to test repeatedly and make sure the experiment can be repeated.
Thus, by repeating an experiment many times, scientists increase confidence in the results. So, the correct option is (A).
