The majority of life on the planet is based on a food chain which revolves around sunlight, as plants make food via photosynthesis.. Chemosynthesis occurs in bacteria and other organisms and involves the use of energy released by inorganic chemical reactions to produce food
Fossils are formed when a plant or animal dies in a watery environment and is buried in mud and silt. Soft tissues quickly decompose leaving the hard bones or shells behind. Over time sediment builds over the top and hardens into rock.
I will support the notion that the human body is made up of the four types of macromolecules which can be seen below:
<h3>What is a Macromolecule?</h3>
These are referred to the large molecules which are involved in the biochemical activities of the body and examples include protein, lipid etc.
All cells in the body however contain all the macromolecules because Protein acts as the building block for the cells while carbohydrates are usually stored in cells as glycogen. Lipids form part of the membrane and nucleic acids such as DNA are present in all parts of the body.

The correct answer for the question that is being presented above is this one: "Yes, because the observed changes in histone modifications are consistent with reduced transcription." The results shown in Figure 19.5 prove conclusively that histone modifications are causing reduced Hnf4a gene transcription because <span>the observed changes in histone modifications are consistent with reduced transcription.</span>
