Ways to bring a change

Assertion : According to Hardy - Weinberg Equilibrium , the frequency an allele remains the same generation after generation. Reason : The only way to bring about a change in by natural selection.

Pollution can brings about change in

A change of 8mA in the emitter current brings a change if 7.9 mA in the collector current. The change in base current required to have the same change in the collector is

A change of 8.0mA in the emitter current brings a change of 7.9mA in the collector current. How much change in the base current is required to have the same change 7.9mA in the collector current?Find the values of (alpha) and (beta) .
