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.
I’m not too sure I think it’s A
applications of biotechnology in the field of agriculture and medicine are:
Antibiotics are created from the plants for human and animal use. An antibiotic protein in stock feed is more cost-effective than traditional antibiotic production.
It helps in the production of genetically modified crops that produce crops with desired characteristics.
Gene therapy is used for the diagnoses of diseases like cancer and Parkinson’s disease.
Genetic testing is another technique that is used to diagnose any genetic diseases in theparents.
DNA fingerprinting is used in the identification of criminals and solving paternity disputes.

Answer:
Choose distinct parallel lines.
Explanation:
They represent two parallel lines. The slopes are going to be the same in each line . Put the x value on the opposite side of the equal sign.
y = - 5x + 3 The slope is - 5
10x + 2y = - 6 Subtract 10x from both sides
2y = - 10x - 6 Divide by 2
y = -10x/2 - 6/2
y =-5x - 3
That minus three is the problem. You have 2 different y intercepts. That means that you have 2 parallel lines.
