Explanation:
The cellulose make stems, leaves and branches. So it play an important role in building of tissues. So it give the shape to plant. The molecules of cellulose have hydroxyl group that form hydrogen bonding with other cellulose and prrovide support to plant.
Sedimentary rocks do not undergo heating it’s metamorphic rocks that do.
Answer:
The correct statements are:
- Sensors in the brain detect a lack of oxygen.
- The muscles in his body need more energy and therefore more oxygen.
The amount of oxygen in air and atmospheric pressure decreases with increase in altitude.
So, when Jon hikes up the hill he faces two problems; lack of oxygen in the air and decrease in atmospheric pressure.
Decreased atmospheric pressure makes it difficult for the lungs to breathe in the air and lack of oxygen decrease the blood oxygen level.
In addition, physical activity like hiking increases the oxygen demand of the body.
Due to these factors the respiratory system struggles to meet the oxygen demand of the body. The brain detect the same and triggers the respiratory and circulatory system to work more in order to meet the oxygen demand.
It causes the shortness of breath or heavy breathing, high blood pressure, tiredness, dizziness etc.
Once the bloold stop circulating through the body, a decomposition process start, five stages take the body from fresh to dry or remains, one the stages is Bloat, and that is a process where the body begins liquefying the tissues and transforming proteins and carbs into gases such as methane, nitrogen, carbon dioxide and hydrogen sulfide, producing at first, distention of the stomach, spreading through the whole body. The increase of gas pressure combined with the presence of liquids, give the body a bloat look and all that elements are forced to leave the body through natural orifices, or because of the weak conditions of the skin, they may break it to scape the body.
