Which of the following is the best definition of a saturated fatty acid?
Oksi-84 [34.3K]
The best choice would be C.

A saturated fatty acid is a basic unit of lipid that consists of only single carbon to carbon bonds.

Saturated fatty acids have been “saturated” with hydrogen ions and only have single carbon to carbon bonds, unlike unsaturated fatty acids that have both single and double bonds and have kinks and aren’t straight.

Saturated fatty acids are solid in room temperature(animal fats) and unsaturated fatty acids are liquid in room temperature(oils/plant fats).

Does the stomach only does chemical digestion to break down food?
bonufazy [111]
In the stomach, food undergoes chemical and mechanical digestion. Peristaltic contractions (mechanical digestion) churn the bolus, which mixes with strong digestive juices that the stomach lining cells secrete (chemical digestion). As food travels from your mouth into your digestive system, it's broken down by digestive enzymes that turn it into smaller nutrients that your body can easily absorb. This breakdown is known as chemical digestion.

Not one of the ways that bacteria have adapted to become resistant to antimicrobial agents.
Dominik [7]

Answer:

Explanation:

An antimicrobial agent is a natural or synthetic chemical that kills or inhibits the growth of microorganisms. Bacteria have a mechanism of transferring genomic material called <em>horizontal gene transfer</em><em>, the movement of genes between cells that are not direct descendants of one another</em>. Horizontal gene transfer allows cells to quickly acquire new characteristics and drives metabolic diversity. <u>One of the characteristics usually acquired is the resistance to antibiotics</u>.

Three mechanisms of genetic exchange are known in prokaryotes:

(1) transformation, in which free DNA released from one cell is taken up by another; (2) transduction, in which DNA transfer is mediated by a virus; and (3) conjugation, in which DNA transfer requires cell-to-cell contact and a conjugative plasmid in the donor cell.

Examples of genes transferred by transducing bacteriophages include multiple antibiotic resistance genes among strains of <em>Salmonella enterica </em>serovar <em>Typhimurium</em>, Shiga-like toxin genes in <em>Escherichia coli</em>, virulence factors in <em>Vibrio cholerae</em>, and genes encoding photosynthetic proteins in cyanobacteria.

Conjugative plasmids use a mechanism to transfer copies of themselves and the genes they encode, such as those for antibiotic resistance, to new host cells.
