Answer: Cytotoxic T cells
Explanation:
A Cytotoxic T cell is a cell whose activation is mainly aimed at destroying cells that are infected by virus. It is a type of white blood cells that destroys cancerous cells or cells that are impaired especially by viruses. A Cytotoxic cell is also known as T-killer cells, Cytolytic T cells, T lymphocyte.
Cytotoxic T cells destroy target cells by prearranged apoptoses.
Cancer cells are the best target to amplify the most within first 2 hours. Highly oncogenic retroviruses are recombinants of viral and host genes.
Retroviruses are viruses with RNA rather than DNA in their genomes that infect cancer cells. Reverse transcriptase is an enzyme that is used to integrate into the DNA of the host cells. It is enhanced to a greater extent the more cell replication takes place. More retroviruses are then produced by the cell, infecting further cells. Many diseases, including AIDS and various types of cancer, are linked to retroviruses.
Low-incidence cancer-causing retroviruses lack inserted host information. Instead, it seems that they alter the expression of potentially carcinogenic host genes, which in turn results in cancer. Retroviruses incorporate proviral DNA into the chromosomal DNA of their host during the course of their regular life cycle. Integrations take place across numerous locations. Although most integrations are benign, some can cause cancer. Many of these seem to encode tyrosine phosphorylating protein kinases.

<span>Parasympathetic nervous system
</span><span>
The nervous system has three general functions: a sensory function, an interpretative function and a motor function. 1. Sensory nerves gather information from inside the body and the outside environment. The nerves then carry the information to the central nervous system (CNS). 2. Sensory information brought to the CNS is processed and interpreted. 3. Motor nerve cells convey information from the CNS to the muscles and glands of the body. The nervous system is responsible for coordinating all of the body's activities.</span>
<span>The answer is general senses. These are the senses which
are professed by reason of the receptors distributed all over the body such as temperature,
touch, and starvation, instead of knotted to a particular structure, like the
special senses - sight or hearing.</span>
