Answer:
D. the law of crosscutting relationships
Explanation:
The law of cross-cutting relationships can help explain the age of the rock as it relates to the surrounding rock.
This law is one of the premise of relative dating. The relationship between the intrusion and rock body or country rock is used to discern their age.
- When intrusions cross-cuts the host rocks, they are usually younger.
- The host rock must haven emplaced before the intrusion sets in
- The intrusion utilizes weak planes within the rock body to cool and solidify.
- Now, when they are emplaced, then a vein or other intrusive bodies forms.

Answer:
B.carries and allows expression of a foreign gene of interest.
Explanation:
Plasmids are the low molecular weight extrachromosomal DNA molecules that are able to replicate themselves independent of chromosomal DNA due to the presence of "ori" (origin of replication).
Plasmids serve as vectors in recombinant DNA technology as some of their genes can be replaced with the gene of interest to create recombinant plasmids.
The restriction enzymes that create the sticky ends and DNA ligases facilitate the insertion of the foreign gene into the plasmids.
The host cells are made competent to take up the recombinant plasmids. Once inside the host cell, the recombinant plasmids replicate themselves and express the gene of interest that they carry.
