Answer:
plasmid
Explanation:
Plasmids are small circular double or singe stranded DNA molecules that are distinct from the main chromosomal DNA. They are used in genetic engineering as vectors for replication of foreign DNA or proteins using bacteria as a host organism. The DNA strand is integrated into the plasmid DNA to form a recombinant plasmid that is then transformed into the host.
Plasmids are ideal vectors because of the following characteristics:
- High copy number per cell
- Multiple cloning sites
- Have an origin of replication
- Have antibiotic resistance gene
There are also diffrent types of plasmids:
- Degradative
- Virulence
- Resistance
- Fertility
- Col plasmid

Answer:
True: D. Simple steps like handwashing and not working with food when sick can help prevent foodborne.
Explanation:
It is false that most foodborne illness is not preventable, they are actually easy to prevent if we follow some recomendations, such as handwashing. Also, not most foodborne illness is caused by vectors, we have 3 categories of: biological hazards, chemicals hazards and physical hazards. It is false that safe handling involves many complicated procedures that require advanced education and training, it is pretty easy. Just by following four steps you get a perfect handwashing.
Cohesion means cohesionrefers to the sticking together of alike molecules, such as water molecule being attracted to another water molecule.
<span>The presence of rigid cell wall that gives the block like structure to the plant cells which is not the case with the animal cells which has soft membranes. Another reason for this kind of maintenance of plant cell shape is that the network of fibers that are present in the cytoplasm called as Cytoskeleton.</span>
