Answer and Explanation:
Some pathogens and pests usually survive and reproduce even when they are exposed to the antibiotics and pesticides repeatedly. These instances show that within the population soe individuals possess the gene for resistance or acquire it through mutation hence survives the chemical. Those that survive transmit this characteristic to their offsprings thus establishing a new population of resistant forms.
Answer:
It is necessary because of the base pairing between the desired gene and plasmid
Explanation:
Restriction enzymes are enzymes that recognize the specific DNA sequence-restriction site, double-stranded cut DNA and produce ends with a single-stranded overhang. The overhangs of the plasmid can stick together with overhangs of gene of interest by complementary base pairing. Joining of ovarhangs is done by the enzyme DNA ligase.
Answer:
They can probably wait to get gas until the next exit.
Explanation:
Easy peasy
Answer:
isotonic: two solutions having the same osmotic pressure across a semipermeable membrane
hypertonic: shrink. solution is one in which the concentration of solutes is greater inside the cell than outside of it
hypotonic: swell. solution is one where the concentration of solutes is greater outside the cell than inside it
