No they don't
For example humans. Technically humans are place below a wild predators such as sharks in trophic levels.
But the fact is we can eat sharks. So , organisms don't always stay in the same level
Answer:
A) Glucose and Oxygen
Explanation:
Photosynthesis takes in water and carbon dioxide and converts it to glucose and oxygen.
Answer:
Aseptic technique is important in the microbiology laboratory health care industry because it reduces the contamination risk that can have serious implications on the health of a person.
If aseptic procedures are not performed in the Microbiology laboratory and health care industry then there would be chances of getting the disease because in health care industries pathogenic samples from patients are processed which can be transferred in the employee while processing if correct aseptic technique is not used.
Aseptic procedures include wearing lab coats and other protective suits while working which cover all body and give protection from entry of pathogens. Sterilization of surface where work is going on, proper sterilization of all pathogenic cultures.
Therefore aseptic procedures are important to avoid contamination in the microbiology laboratory.
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.
