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.

vaieri [72.5K]

Answer:

Neuroscientists conducted research with taxicab drivers in London and found that taxicab drivers, who are required to have a tremendous amount of spatial and geographic knowledge, had a larger <u>hippocampus</u> than other drivers.

Option D.hippocampus

Explanation:

Hippocampus is concerned with following important functions:

  • Storage of new information in the memory (converting short memories into long memories)
  • Comparing sensory information with what the brain expects about the world
  • Enabling us to form spatial memories for investigating the environment

As the geographic knowledge and spatial knowledge is being stored in the hippocampus, the taxi driver surely have greater hippocampus than other drivers.

Why is growth and reproduction of a cell cycle?
vovangra [49]

Answer:

In addition, a larger cell is less efficient in moving nutrients and waste materials across the cell membrane. - Asexual reproduction is the production of genetically identical offspring from a single parent. During the cell cycle, a cell grows, prepares for division, and divides to form two daughter cells.
