C. Over many generations, the characteristics of these kinds of organisms also change

Family programmes help to reduce the rates of poverty, over population etc.
<h3><u>Explanation:</u></h3>
Family programming is a scientific approach to initiate a control over the reproduction of eligible couples in a particular population. Family plannings are initiated by the government as well as should be adopted by the couples in order to maintain a very healthy relationship as well a healthy population.
Family planning helps to reduce the poverty, hunger, epidemics, sexually transmitted diseases like AIDS etc and improves the maternal health, infant health, reduces maternal mortality rates, infant mortality rate, neonatal mortality rate etc. This uses the basic contraceptive methods as well as different other factors like when to take a baby and all.
Answer:
the answer is A. E. coli B
Explanation:
The multiplicity of infection (MOI) refers to the ratio between the numbers of viruses used to infect <em>E. coli</em> cells and the numbers of these <em>E. coli </em>cells. Benzer carried out several experiments in order to define the gene in regard to function. Benzer observed that <em>E. coli </em>strains with point mutations could be classified into two (2) complementary classes regarding coinfection using the restrictive strain as the host. With regard to his experiments, Benzer observed that rII1 and rII2 mutants (rapid lysis mutants) are complementary when they produce progeny after coinfect E. coli K (where neither mutant can lyse the host by itself). The rII group of mutants studied by Benzer does not produce plaques on <em>E. coli</em> K strains that carry phage λ (lysogenic for λ), but they produce plaques on <em>E. coli</em> B strains. This study showed that rIIA and rIIB are different genes and/or cistrons in the rII region.
