Answer:
They transcribe RNA to DNA using reverse transcriptase.
Explanation:
<u>Retrovirus</u>
A type of virus that uses RNA as its genetic material. After infecting a cell, a retrovirus uses an enzyme called reverse transcriptase to convert its RNA into DNA. The retrovirus then integrates its viral DNA into the DNA of the host cell, which allows the retrovirus to replicate. HIV, the virus that causes AIDS, is a retrovirus.
Retroviruses have an enzyme, called reverse transcriptase, that gives them the unique property of transcribing their RNA into DNA after entering a cell.
Question 1. i would say psychology took so long to be recognized because people only thought the problem was in their physical body not their minds and they thought if you just fixed your physical body then your would be fine
<span>Combustion reaction is a chemical reaction where compounds and oxidants produce heat and new product during their reaction. The reaction between a HC (hydrocarbon) and O (oxygen) to produce CO2 (carbon dioxide) and H2O (water) is a standard form of a combustion reaction. Therefore,the correct answer would be A.
It is the combustion of gas (Methane, CH4) when it encounters oxygen (2O2). Methane will burn forming C02 gas and H20 gas.</span>
A theory is an explanation that ties together many hypothesis.
- A well considered explanation for observations of the natural world that has been developed through the scientific method and that combines numerous facts and hypotheses is known as a theory.
- A scientific hypothesis offers a suggested resolution based on data, as opposed to an educated assumption.
- A thorough explanation of a significant aspect of nature that is supported by data acquired through time is referred to be a theory. Predictions concerning occurrences that have not yet been observed can also be made by scientists using theories. A scientific theory is a well-supported explanation of a particular phenomenon in the natural world that is based on a body of facts that have been repeatedly verified via observation and investigation.
- In that they are guiding principles that can be utilized to forecast behavior, scientific laws are comparable to scientific hypotheses.
Therefore, theory is the correct answer.

Answer:
B. Molecular Systematics
Explanation:
First, let's review a few definitions. DNA, deoxyribonucleic acid: an extremely long macromolecule that is the main component of chromosomes and is the material that transfers genetic characteristics in all life forms, constructed of two nucleotide strands coiled around each other in a ladderlike arrangement with the side pieces composed of alternating phosphate and deoxyribose units and the rungs composed of the purine and pyrimidine bases adenine, guanine, cytosine, and thymine: the genetic information of DNA is encoded in a sequence of the bases and transcribed as the strands unwind and replicate. Molecular systematics is a scientific discipline that uses nucleic acids or other molecules to infer. evolutionary relationships between different species.
