All living things are made up of more than one cell
Answer:
Release or egress
Explanation:
Virus can reproduce only within a host cell, this cycle of infection begins with the <em>attachment</em>, where the virus attaches to a specific receptor site on the host cell, after this comes the<em> entry,</em> in the case of enveloped virus, the envelope can fuse directly with the cell membrane to enter the cell, they can also enter through endocytosis. After entering the cell the virus initiates a <em>replication and assembly </em>mechanism depending on its genome, finally, the last stage of viral replication is the <em>release or egress </em>of the new virions produced in the host organism, some viruses can be released when the host cell dies, but some can leave infected cells by budding through the membrane without directly killing the cell.

1) Because we are constantly discovering new species of organisms, the system of classification is growing.
2) In order for scientists to write, learn, and retrieve data about organisms, there most be an organized filing system in place.
Answer:
The vector, that is , the bacterium is encoded by the antibiotic resistance gene.
Explanation:
A recombinant organism is the organism that its genetic makeup has been altered, this means , the organism contains different combination of alleles, that can't be found in either of the parents. This is usually done by deliberately introducing new genetic materials or elements.
The offspring produced by these altered organisms also possess the new genetic material that was initially introduced to the altered organisms.
Bacteria have been the most desired organism for this act, because they are easy to grow and nurture.
Answer:
Option A, Viruses contain either DNA or RNA.
Explanation:
Virus is a non-living microscopic molecule that requires a host to live in and reproduce. All the viruses have nucleic acid either in the form of DNA or RNA. DNA or RNA is genetic material that is enclosed with in a membrane known as capsid. Capsid is also made up of protein. They are extremely small, even smaller than a normal cell and only consist of package of nucleic acid and protein.
Hence, option A is correct
