Answer:
The hypothesis that states that viruses originated from more complex cells is called the regressive hypothesis.
Explanation:
The regressive hypothesis -also called <u>degenerative hypothesis</u>- raises the possibility that viruses originally were cells that behaved as symbionts or parasites of other cells, and this condition of dependence could have originated the disappearance of genes, becoming structures formed by nucleic acid inside a viral capsid (virus).
Some evidence gathered to support this theory suggests that some bacteria, such as rickettsia, need to parasitize a cell in order to replicate, just as viruses do.

Answer:
Bioluminescence is the production and emission of light by a living organism. It is a form of chemiluminescence. Bioluminescence occurs widely in marine vertebrates and invertebrates, as well as in some fungi, microorganisms including some bioluminescent bacteria, and terrestrial arthropods such as fireflies.
Explanation:
The question is incomplete as it does not have the attached DNA gel which has been attached.
Answer:
No
Explanation:
In the given question, the DNA of the boy was compared with the DNA samples of his father and mother.
The DNA if these people were collected and PCR was performed to duplicate the DNA. These DNA samples were then analysed on the Gel electrophoresis in which the bands were visualized with the UV light.
In the band, we observe that the size of the DNA fragments was not similar to the DNA sample of the women but a band was of similar size to the father.
Since the bands are of different size of the boy when compared to the mother, therefore, the women are not the mother of the boy.
Thus, No is the correct answer.
Given what we know, we can confirm that both gamma rays and x-rays can be used to slow the decay process in foods.
<h3>What are gamma rays and x-rays?</h3>
- Both of these are forms of ionizing radiation.
- Applying these to food is known as food irradiation.
- What this accomplishes, is that the food that is irradiated will have its chemical bonds altered, slowing the decay process.
Therefore, since both gamma rays and x-rays offer ionizing radiation to the food, which affects the chemical bonds and allows the food to have a longer shelf life, we can confirm that they can be used to slow the decay process in foods.
