Answer:
The thoracic cavity is "Superior" to the abdominopelvic cavity. Superior ... If an incision cuts the heart into right and left parts, a "Sagittal" plane of section was used
Explanation:
The thoracic cavity is mainly located in the chest region which also have neck and the diaphragm in it. In the thoracic cage the thoracic organs are safely placed. The thoracic cavity lies above the abdominopelvic region. The sagittal plane is the vertical plane which runs from the front to back of the body. The sagittal plane helps in splitting of two equal halves like the left and right one.
The genetic code<span> is called a </span>universal code<span> because all known organisms use the same four nucleotide bases; organism differ according to the arrangement of the nucleotide bases. The four nucleotide bases are adenine , thymine, cytosine and guanine. Three bases form an amino acid, also known as a codon</span>

Answer:
D. The virus uses the host cell to make new viral parts.
Explanation:
The virus is an organism that is incapable of replicating on its own without a living host cell. It needs to infect a living cell in order to reproduce. The infection cycle of a virus is the replication cycle. Viruses employ two major infection cycles: LYTIC or LYSOGENIC cycles.
In the lytic cycle, the virus initially attaches to specific receptor sites on the host cell membrane. It then penetrates the host cell and incorporate its genetic material into the host cell's genome. It employs the host's ability to express its genes and replicate to express its genes and make new proteins. At the end of the LYTIC cycle, new viral particles (virions) are produced and released by lysis of the host cell.
