Answer:
support and regulate the bodies homeostatis
Explanation:
Homeostatis is a type of mode your body goes into when it has no food for a prolonged period of time your body essentially eats your own fat to live

Answer: D) retroviruses
Explanation:
Retroviruses are a type of virus that converts its genetic material into DNA using a special enzyme, called reverse transcriptase. The DNA is then able to integrate into the DNA of the host cell. Once integrated, the virus can make additional viral particles using the components of the host cell.
Retroviruses which cause cancer at low incidence do not contain host information inserted. Rather, they tend to cause cancer via the expression mutation of potentially oncogenic host genes. Retroviruses incorporate proviral DNA into their host's chromosomal DNA during their natural life-cycle. Provirus DNA promoter affect regulatory gene expression over.
Hence, the correct option is D.
1. Energy from the Sun ejects electrons from chlorophyll and splits water molecules to yield hydrogen ions.
Pigments inside the photosystems absorb light energy. Energy is transferred to reaction center, where electron is boosted at higher level. Electron is then passed to an acceptor molecule, replaced with an electron from H2O. and O2 is released.
2. Electrons move down the electron transport chain, releasing energy that pumps hydrogen ions into the thylakoid space
Electron releases energy because it goes from a higher to a lower energy level.
3. The concentration of hydrogen ions in the thylakoid space increase
Released energy of electrons drives pumping of hydrogen ions from the stroma into the thylakoid interior, building a proton gradient.
4. Hydrogen ions diffuse across the thylakoid membrane into the stroma through ATP synthase.
The only way for hydrogen ions to move down the gradient is through ATP synthase.
5. ATP synthase uses the energy released as hydrogen ions move from regions of high concentration to regions of low concentration to make ATP.
ATP synthase is an enzyme that use proton gradient to make ATP from ADP and Pi.
Answer:
Being endothermic
Explanation:
Humans are not cold-blooded and we don't photosynthesise so only the second option applies to humans;
We produce heat internally within our bodies so we are endotherms, i.e. warm-blooded;
We shiver and have thermogenesis through metabolism to generate heat to keep body temp up and also sweating and physiological mechanisms to cool out bodies down.
