3) Don't go to places where you doubt the presence of X-Ray Radiations.

4) If not needed, Don't do CT scan.

Distance and shielding can protect a person from X Ray radiation. An example could be how X Ray technicians go into a room that’s away from you whenever you get an x ray at a hospital. Distance is effective because it can reduce exposure. Hope this helped!

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.

Why must most antibiotics be given some time to take effect on a disease-causing population of bacteria?
Eva8 [605]
The correct answer is d. "Regeneration" means "forming new cells," and signifies that the disease-causing bacteria cells are multiplying. When there are more of these cells, there is a higher chance for antibiotic resistance (making it take longer for the antibiotics to work). Once there is a smaller concentration of these bacterial cells, the antibiotics become more effective.

AlexFokin [52]

GMOs have been changing the way that pesticides are used in agriculture. Herbicide-tolerant genetically modified (GM) crops have led to an increase in herbicide usage while insecticide-producing GM crops have led to a decrease in insecticides.
