Answer:
see below :)
Explanation:
There are three types of ecosystems; freshwater, ocean, and terrestrial.
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.

Answer:
The correct answer is d the positive feed back reduces change in the the system
Explanation:
In an biochemical reaction when the released product stimulate the release and activation of the same product and act together to exibit their biological function, then this type of regulation is called positive feedback.
The positive feed back mechanism leads to increased change in the system that"s why it is named so.
For example during blood clotting platelets molecules are released to form clots to stop bleeding. one activated platelet can stimulates the activity of other platelets which then join together to form a group for generating further blood clots.
