Answer:
The correct option is D. Drug-resistant populations of microbes arise when exposure to drugs selectively kills sensitive cells, allowing overgrowth of resistant cells.
Explanation:
Drug- resistance can be described as a mechanism through which an organism can overcome the effect of a drug.
Usually, exposure of a drug again and again to a population of microbes will make the microbes resistant to that drug. The cells of the microbes undergo some change to overcome the effect of that particular drug.
A population of drug-resistant microbes might occur when the sensitive microbes get killed by the drug and resistant strains remain alive.
Answer:It could increase the levels of dust mites
Explanation: duh pay attention in class DUH
A black asphalt road, because darker surfaces attract more sunlight, and asphalt is not a smooth surface (has gravel), and surfaces that are not smooth will also attract more sunlight. There, a black asphalt road will be hotter
The Answer is B because distance in that question refers to the distance from the object to the center of the earth
Answer:
The answer is reciprocal chromosomal translocation
Explanation:
The Philadelphia chromosome (Ph) is the truncated chromosome 22 generated by the reciprocal translocation t(9;22)(q34;q11) and was first identified in 1960 in a patient with CML [3]. Translocation of the proto-oncogene tyrosine-protein kinase (ABL1) gene located on chromosome 9 to the breakpoint cluster region (BCR) gene located on chromosome 22 results in a BCR-ABL1 fusion gene on the Ph [4, 5]. Three BCR-ABL1 fusion gene hybrids encode BCR-ABL1 protein isoforms p210, p190, and p230, which have persistently enhanced tyrosine kinase (TK) activity. These aberrantly activated kinases disturb downstream signaling pathways, causing enhanced proliferation, differentiation arrest, and resistance to cell death [6, 7]. Tyrosine kinase inhibitors (TKIs) targeting the BCR-ABL1 protein are the most successful targeted therapy for Ph-positive leukemia.
