What is the process where organisms that are better suited to their environment reproduce and pass on their genes more successfu
maxonik [38]

Answer:

Natural selection

Explanation:

Natural populations have variations. Organisms of a population have various genetic traits. Some of these genetic variations make the organisms better suited to the prevailing environmental conditions. These organisms are more likely to produce more progeny. Over generations, the frequency of the beneficial genetic traits increases in the population due to the higher reproductive success of the organisms with these genetic traits.

This process of differential fitness of organisms of a population where the organisms with adaptive genetic traits have survival and reproductive benefits is called natural selection.

Streptomyces griseus produces the antibiotic Streptomycin, which inhibits protein synthesis by binding to ribosomes and preventi
VLD [36.1K]

Answer:

See the answer below.

Explanation:

Antibiotic-producing bacteria are generally known to have a mechanism that enables them to be resistant to their own antibiotics. The mechanism that enables them to be resistant to their own antibiotic depends largely on the mode of action of the antibiotic substance.  

Some of the popular mechanisms used by bacteria to counter their own antibiotic substance include a mutation in the target gene, production of enzymes that inactivate the antibiotic compounds, or efflux of the compounds.

<u>In the case of </u><u><em>Streptomyces griseus</em></u><u>, the inactivity of streptomycin has been linked with the production of a phosphatase inhibitor that prevents streptomycin from getting access to the target site. Hence, the organism is not harmed by its own antibiotic.</u>
