Answer: Traditionally in medicine, a vector is an organism that does not cause disease itself but which spreads infection by conveying pathogens from one host to another. Species of mosquito, for example, serve as vectors for the deadly disease Malaria. A vector is a living organism that transmits an infectious agent from an infected animal to a human or another animal. Vectors are frequently arthropods, such as mosquitoes, ticks, flies, fleas and lice. brainliest
Explanation:
If a bacterium cannot use citrate agar will not change its color (stays green). On the other hand, if bacteria have the ability to use citrate, the medium will change its color from green to blue.
This happens because citrate agar contains pH indicator such as bromothymol blue which transforms from green to blue in alkaline conditions.
The correct sequence is:
a) Antibiotics: These antimicrobial drugs used to treat and prevent bacterial infections.
b) Antibiotic resistance: This sort of resistance occurs when bacteria are fully developed into the body and are able to defeat the drugs which designed to kill them. When certain bacteria become resistant, the antibiotics are unable to fight them, and hence they increase and affect the body.
c) Binary fission: Binary fission is a sort of asexual reproduction in prokaryotes such as bacteria. It is found in unicellular eukaryotes like Amoeba and Paramecium.
d) Conjugation: It is the transfer of genetic material between bacterial cells by the direct or bridge-like connection between cells.
e) Mutations: is a permanent alteration in the DNA sequence resulting in a gene, such that the sequence differs from the sequence found in human beings.
f) DNA replication: is the biological process that occurs in all living organisms to produce two identical replicas of DNA from a DNA molecule.
g) Genetic recombination: During this process, offspring are produced with the combinations of traits that are different from the traits found in either parent.
h) Genetic variation: It’s the variation in the DNA sequence in each of human genomes, making every human being unique in terms of hair color, skin color or the shape of their faces.<span>

Explanation:
Answer:
Recombinant DNA is a technology scientists developed that made it possible to insert a human gene into the genetic material of a common bacterium. This “recombinant” micro-organism could now produce the protein encoded by the human gene. ... There, the recombinant bacteria use the gene to begin producing human insulin.
