True. Some bacterial cells are resistant to a variety of antimicrobials because they actively pump the drugs out of the cell.
A significant resistance mechanism in Gram-negative bacteria is drug efflux. It expel solutes from the cell. Antimicrobials and metabolites are just a few of the hazardous compounds that Efflux pumps help bacteria remove from their interior environments so they can regulate it.
The main efflux systems in Gram-negative bacteria are members of the RND superfamily and typically consist of an outer membrane protein channel, a periplasmic protein, and a cytoplasmic membrane pump. The most common example is MFS (such as Bmr and Blt in Bacillus subtilis) and the ABC transporters.

Answer:B. is false
Explanation:
Once RNA polymerase and its related transcription factors are in place, the single-stranded DNA is exposed and ready for transcription. ... Three of the four nitrogenous bases that make up RNA — adenine (A), cytosine (C), and guanine (G) — are also found in DNA.
Answer:
Tt Rr WW
Explanation:
Given:
1. tall (T) is dominant to short (t)
2. red flowers (R) is dominant to white flowers (r)
3. wide leaves (W) is dominant to narrow leaves (w)
4. Also, a tall, red, wide-leaved plant is crossed to a short, white, narrow-leaved plant
To find: genotype (with correct arrangement of alleles) of a tall, red, wide-leaved parent
Solution:
Genotype (with correct arrangement of alleles) of a tall, red, wide-leaved parent is Tt Rr WW
