This refers to a trait that should be able to be treated with antibiotics but instead the trait has built up a resistance to this trait, sometimes this will even make the trait stronger. This can become fatal if the trait is resistant to all antibiotics available

Antibiotic resistance is the ability of a microorganism to withstand the effects of an antibiotic. It is a specific type of drug resistance. Antibiotic resistance<span> evolves naturally via natural selection through random mutation, but it could also be engineered by applying an evolutionary stress on a population.</span>

Kruka [31]

Answer:

The correct answer is B high levels of lactose and high levels of cyclic AMP.

Explanation:

Lac operon contain 3 regulatory genes and 3 structural genes.In presence of lactose the repressor molecule that is encoded by Lac I gene cannot bound to the operator region.

        Bacause the lactose interact with the repressor and change its conformation so that it cannot repress the expression of the structural genes of lac operon.

  On the other hand cyclic AMP is a positive regulator of  lac operon .The interaction of cyclic AMP with the promoter region of lac operon stimulates the binding of RNA polymerase in the promoter region to boost the expression of structural genes of lac operon such as Lac Z,Lac Y and Lac A.

Art [367]

The amount of sagebrush would increase, which would lead to an increased population of jackrabbits, as sagebrush their food source. As the amount of jackrabbits increase, it gets easier for coyotes to hunt for them which in return, increases their survival rate/population.

What is unusual about Earth’s mantle being exposed?
cluponka [151]

Answer:

There is no actual way that the mantle could be...'exposed' or 'seen'. But scientists have managed to find multiple ways to analyze the mantle and it's actual existence by using multiple devices. The mantle is basically a 2,900 kilometers (1,802 miles) thick blocks of rocks and minerals underneath the crust(or the surface of the earth) , and makes up a whopping 84% of Earth's total volume.

Hey There

how are you

the answer to your question is

Acute time limited




Stressors can assume a number of patterns in relation to time. They may be classified as acute time-limited, chronic intermittent, or chronic sustained. An acute time-limited stressor is one that occurs over a short time and does not recur. A chronic intermittent stressor is one to which a person is chronically exposed intermittently; chronic sustained is continuous. PTSD is characterized by a severe stress response secondary to experiencing previous trauma.


thank you
