One advantage of genetic engineering is the production of valuable proteins: recombinant DNA made possible the use of bacteria to produce proteins of medical importance such as genetically engineered human insulin which is of great importance.
Another advantage is the production of vaccines. Vaccines produced by genetic engineering offer an advantage that the microbial strains from which proteins are extracted do not contain complete viruses and thus there is no risk of accidental inoculation with live virus.
Answer:
After the aphotic zone, there's complete darkness. From 1,000 meters below the surface, all the way to the sea floor, no sunlight penetrates the darkness
Explanation:; and because photosynthesis can't take place, there are no plants, either.
Answer:
b
Explanation:
nitrogen will slowly go down due to not having enough organic matter
The balanced equation is
<span>8SO2 + 16H2S ----> 3S8 + 16H2O
</span>so
77g SO2 / 64g/mole = 1.203moles of SO2
<span>77g H2S / 34g/mole = 2.26moles of H2S
</span>now
<span>1.203 moles SO2 yields 3/8x amount that is = 0.456moles of S8
</span>so
<span>2.06moles H2S yields 3/16x amount = 0.386moles of S8
</span>hence
H2S = produce only 0.386moles of S8 = 98.98g S8
hope it helps
