Answer:
Sensitization.
Explanation:
Hypersensitive reaction may be defined as the exaggerated or hyper response of the immune system. Hypersensitive reactions can occur due to auto immunity and allergies.
Type I hypersensitive reaction is mainly mediated by IgE antibodies. The sensitization towards particular stimuli like pollen grains may exaggerate the Type I hypersensitive reaction.
Thus, the correct answer is option (1).
DNA replication initiates at specific points, called origins, where the DNA double helix is unwound. A short segment of RNA, called a primer, is then synthesized and acts as a starting point for new DNA synthesis. An enzyme called DNA polymerase next begins replicating the DNA by matching bases to the original strand.

Air pollution is toxins in the air that are usually created by humans activites
Answer:
Faunal succession
cross-cutting relationships
superposition
Explanation:
Relative dating helps determine geological events by observing rocks.
Faunal succession is a method that uses sedimentary rocks for dating by observing the plant and animal fossils in them.
Cross-cutting relationships show that the layer that cuts across other layers are younger than the layers that they cut through.
Superposition states that younger layers are formed on top of the older layers. So if you are looking at the layers beneath the Earth, the ones that are in the bottom are older and as time pass younger layers form on top of them.
