When dissolved in water, hydrogen ions are released from acids and hydroxyl ions are released from bases Good luck!
1) Since plants are a renewable resource and oil is not, we will eventually run out of the materials needed to make traditional plastic, but we will not run out of what we need to make plant-based plastic.
2) Farming has a much lower carbon footprint than oil extraction and processing does.
3) Plant-based plastic can be biodegradable.
During photosynthesis, plants use carbon dioxide and water to make sugar and oxygen. Some of this sugar, which is found in a variety of hydrocarbons, is recycled within the chloryphll.
the higher the altitude, the lower the oxygen available.
The answer is an envelope.
A virus is an infectious agent that can replicate only inside a host cell. When it is outside the cell, it consists of genetic material coated with protein capsid. Some viruses also have an envelope which covers capsid. The function of the envelope is to identify and bind some receptor sites on the host membranes. After fusing with the cell membrane, it allows to capsid and genetic material to enter the cell and infect it.
