"C" Climate change, because if the past time had more hurricanes than in these times, then the weather has changed. .
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.
The lining attached to the lungs is called the visceral pleurae.
<span>Mollusks are sometimes hard to classify because there are not a lot of characteristics they all share.
</span>True
Mollusks are not a very diverse group; there are very few body plans.
False
<span>Generally, mollusks have a soft body and most have a shell.
</span>True
<span>Gastropods and bivalves are types of arthropods.
</span>False
<span>Cephalopods are the smartest types of invertebrates.
</span>Lol that's sooo False
<span>Octopuses have been known to figure out latches and escape their tanks.
</span>True
<span>Snails and slugs are bivalves.
</span>False
Answer:
B. inhibit the germination of Clostridium botulinum endospores.
Explanation:
Nitrite is used in meat curing, which is produced commercially as sodium nitriteand it is has been responsible for the preservation and characteristic color/ flavor of the cured meats. Cured meat products contain curing salts, usually salt (sodium chloride) and either nitrites or nitrates. The function of nitrite in processed meat is : (1) to stabilize the color of the lean tissues. Sodium nitrite, is most commonly used for curing (although in some products such as fermented ones, sodium nitrate is used too, because of the long aging period); pocessed meats like as bacon, ham, sausages etc.
These compounds help to prevent the growth of harmful bacteria. add a salty flavor. Clostridium botulinum produces heat-resistant endospores that are commonly that are able to survive under adverse conditions. Clostridium botulinum is commonly associated with bulging canned food; bulging, misshapen cans are due to an internal increase in pressure caused by gas produced by this bacteria.
