Answer:
a virus, because it requires a host cell to reproduce
Explanation:
- a bacterium, because it is contagious
-
a fungus, because it infects livestock
-
a protist, because it is microscopic
-
a virus, because it requires a host cell to reproduce
The correct answer would be <u>a virus because a virus is the only microbe that cannot reproduce on its own without a host</u>. A virus utilizes the genetic mechanism of its host to reproduce either lytically or lysogenically.
<u>In lytic cycle</u>, the virus utilizes the genome system of the host to produce more viruses that eventually leave or lyses the host to become independent viral particles, killing the host in the process.
<u>In lysogenic cycle</u>, the virus inserts its genome into that of the host and uses the host's replication machinery to replicate its genome. The virus then waits for the defense mechanism of the host to become weakened before multiplying and lysing the host.
Although errors might happen during the transcription or translation process, the fact that amino acids are being coded by a number of different codons would offset the error. This would offset the transcription and translation errors because there are a number of codons present so even though a wrong match or pairing of the letters would happen, another type of codon having those letters would be present which results to not becoming an issue or being a bad type of mutation. It would basically decrease chances of a transcription or a translation process would cause an erroneous type of protein formed.
The answer is ("B" - is the foundation of the scientific method.)
