Natural selection is the mechanism responsible for the antibiotic resistance of E. coli.
Natural selection is a mechanism that favors the adaptation of organisms to survive in their environment, thrive and reproduce.
In the context of antibiotic resistance, antimicrobial substances exert selective pressure on microbes that encourages the evolution of resistance.
Those capable of resisting the effects of antibiotics survive and reproduce, while the vulnerable either die or have their growth inhibited.
The excessive and inappropriate use of antibiotics favors selection for antibiotic resistance in bacteria.
E. coli is characterized by having Gram negative bacilli, it represents the greatest risks of zoonotic transfer of resistance.
In general, and when a treatment is short, there is an elimination of sensitive saprophytic strains of E. Coli and an enormous predominance of resistant strains.
Bacteria also acquire antimicrobial resistance through vertical or horizontal transfer of genetic information.
Therefore, we can conclude that resistance to antibiotics in E. coli is due to the process of natural selection since it evolves to resist the action of an antimicrobial agent.

Explanation:
Describe the processes of metabolism and photosynthesis
Carbon dioxide is converted into sugars in a process called carbon fixation; photosynthesis captures energy from sunlight to convert carbon dioxide into carbohydrate. ... These nutrients are oxidized to produce carbon dioxide and water, and to release chemical energy to drive the organism's metabolism.

The flow of genetic information in molecular biology follows the following path, A) DNA is translated into protein B) DNA is transcribed into RNA which is translated into protein C) DNA is translated into RNA which is transcribed into protein D) RNA is transcribed into protein
Answer:
The Correct answer is DNA is transcribed into RNA which is translated into protein
Explanation:
The genetic information is unidirectional, from DNA to proteins. First, DNA is transcribed into an intermediary RNA molecule is known as transcription (TC), a further messenger RNA molecule (mRNA) is translated into a corresponding sequence of amino acids (translation). This concept of information flow is known as the central dogma of molecular biology.

A person lives on the Tropic of Capricorn. What is the altitude of Polaris?
O 23 1/2"
O 90°
O 66° 33"
O 15°
O 30°
O 45°
The correct answer as to what the altitude of Polaris would be for a person that lives on the Tropic of Capricon is 23° 1/2".
Polaris is a star and the altitude of any star is its height above the horizonThe Polaris is otherwise known as the North star as an indication that it is directly located overhead the north pole. Thus, it may not be visible once one moves South of the equator. The tropic of Capricon is located approximately 23° 1/2" South of the equator. In other words, the latitude of the Tropic of cancer is approximately 23° 1/2".Hence, the altitude of the Polaris at an altitude of 23° 1/2" will also be 23° 1/2", although it will most likely remain invisible.A person that lives on the Tropic of Capricon is approximately on latitude 23° 1/2". Since the altitude of a star is its height above the horizon, the altitude of Polaris from the Tropic of Capricon would, therefore, be 23° 1/2"

Compare types of models. Which model of the human digestive system is most detailed?
A. Photograph of digestive system
B. Dissected pig
C. Artist drawing
D. 2D computer-generated model
The model of the Human digestive system that is most detailed is ( B ) : Dissected Pig
Pigs and Human have similar internal organs and the locations of each organ in both mammals are similar as well, therefore from the options the closest model that is most detailed as regards to the Human digestive system is a dissected pig.
A photograph of the digestive system does not provide a detailed model, also an artist drawing cannot provide as much detail as needed. A 2d computer-generated model will only present the digestive system in 2 dimensions hence it is not detailed enough as well.
Hence the most detailed model is a Dissected pig model.

Explanation:
Viruses and bacteria can infect human cells. Bacteria are living organisms, while viruses are not. How do you think the treatment for viral and bacterial illnesses differ? How do you think they affect healthy body cells? Explain your response.
Answer:
hope it helps
Explanation:
1) antibiotic drugs can kill bacteria however, they are not effective against viruses
2) some bacteria's help to digest foods and speed up enzyme reactions. Some bacteria cells destroy disease causing cells
The treatment for viral and bacterial illnesses differs primarily due to the fundamental differences in their nature and characteristics. Bacteria are living organisms that can be targeted by antibiotics, whereas antiviral medications are used to treat viral infections.
Both bacteria and viruses can affect healthy body cells, with bacteria directly invading cells and causing damage, while viruses rely on host cells for replication and can induce damage during the process.
Bacteria and viruses can both cause damage to host cells. Bacteria can directly invade and damage cells through mechanisms such as releasing toxins or inducing inflammation.
Viruses require host cells to reproduce. They invade host cells, hijack cellular machinery to replicate themselves, and subsequently cause damage to the infected cells during the process.
