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.
7. b and 8. c i attached the photo for u to see how i did it
When forests have been cut down, new native trees can be planted
Answer:
most of them require food and oxygen
Explanation:
the plants take the food from the underground and the animals take there food not from the underground but they still eat, so the need food. the oxygen ist normally, when you put plants in a place where is no oxygen they will die, the animals need oxygen too. If you put an animal in a room/place where is no oxygen they will die
Other organisms such as an autotroph
