I think the answer is two
Aspects such as genetic engineering have allowed for
engineering of transgenic organisms such as bacteria to produce bioproducts
such as insulin to addresses medical disorders
such as diabetes. Another is the innovation of whole-genome sequencing that allows researchers
to determine genetic predisposition of a particular person to particular diseases.
I would say B, because as you can see from the explanation of what a luster is described is. B matches the classifications
The viruses that lie dormant in host cells until ready to multiply use : Lysogenic cycle
During the lysogenic cycle the virus do not kill the host. It integrate it's dna with the host's so it could lie dormant until it ready to multiply
Hope this helps
Colder air masses are temped Polar or Arctic. While warmer air masses are termed Tropical. Continental and Superior air masses are dry while maritime monsoon air masses are moist. Weather fronts separate air ,asses with different density (Temperature and/or Moisture) characteristics.
