I. Each carbon atom can form single bonds with up to four other carbon atoms. II. Each carbon atom can form double bonds with up to two other carbon atoms. III. Carbon atoms can join together to form chains or rings. IV. A single molecule of some compounds can contain thousands of carbon atoms.
Answer:
All the given choices
Explanation:
Carbon is a very interesting element which is the backbone of most organic compounds.
Organic compounds are made up of carbon. Carbon forms a wide range of compound due to the following properties;
- An atom of carbon has 4 valence electrons and can bond with 4 other carbon.
- Carbon can form single, double and triple covalent bonds.
- They can join together to form rings or chains.
Process of photosynthesis makes glucose. Excess glucose is stored as starch, or made into cellulose in cell walls.
The hero changes from being happy to depressed or unhappy
Answer:
It could lead to the changes in the earths surface because it could open up geysers in the crater, causing the earths surface to change.
This layer is called the cell wall.
The cell wall is located outside the cell membrane and provides the cells with structural support and protection. It gives cells rigidity and strength, offering protection against mechanical stress.
In most cells, it is flexible, meaning that it will bend rather than hold a fixed shape, but has a lot of tensile strength which is necessary to be able to withstand internal osmotic pressure.
Cell walls are found in plants, bacteria, fungi, algae and some archaea.
