Mutations rII1 and rII2 are known to fall into the rIIA and rIIB cistrons (genes) respectively. Cells of E. coli B are infected
viktelen [127]

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.

If the net force an object at rest is zero the object will remain at rest. <br> True or false
FromTheMoon [43]

True

Explanation:

If the net force on an object at rest is zero, the object will remain at rest. This is one of the postulates of newton's law of motion.

 Newton's first law of motion states that "an object will continue in its state of rest or uniform motion unless if it is acted upon by an external force. "

  • If no net force acts on a body, it will forever remain at rest.
  • The force on a body causes its motion and acceleration.
  • A body will continue in uniform motion if no external force acts on it.
