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.
Basically it will just regenerate its body and continue being a starfish no matter how much you cut from a starfish it will regenerate
Answer:
transpiration is the process by which plants loses water vapour to the atmosphere
Risk factors and prevention of diabetes mellitus
Explanation:
It is to enable clients to prevent illness is one of an
important nursing function. The nurse should most appropriately educate the
family about the risk factors and prevention of diabetes mellitus. Knowledge of
the medications used to treat diabetes is not necessary at this time and does
not help meet the family's needs. The severity of the client's disease does not
have an impact on the family's health. Knowledge of the cellular metabolism of
glucose is not necessary for the family's health.
