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.

The answer is c (I think)
The two DNA strands are held together by hydrogen bonding between the bases on the different strands; therefore, all the bases are on the <u>inside of the double helix</u>, and the sugar-phosphate backbones are on the <u>outside.</u>
<u></u>
The two strands are held collectively via hydrogen bonds between pairs of bases: adenine pairs with thymine, and cytosine pairs with guanine.
Covalent bonds arise inside every linear strand and strongly bond the bases, sugars, and phosphate groups (each within each thing and between additives).
Hydrogen bonds occur among the two strands and contain a base from one strand with a base from the second in complementary pairing.

Explanation:
Answer:
Bar and lexical.
Explanation:
Bar and lexical are the name of two different types of scales that are found on maps. Bar scales are used more frequently in the maps because they represent or show the distance ratio visually instead of in words, while on the other hand, lexical scales may be expressed in words, as a ratio, or as a fraction. Examples are 1:10,000 or 1/10,000. Using map scales is very important in the real world if you want to find out the distance you are traveling.
