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.
Dispersal helps different species to increase their range of places, thereby helping to increase their population size in different regions. Dispersal also helps to avoid crowding of diseases of a single location as species move to different locations.
<h3>What is dispersal?</h3>
- Dispersal is the act of distributing things over a large area. It is when the individuals or seeds move from one site to their growing site.
- Dispersal can be active (move by oneself) or passive (require dispersers).
- Seed dispersal is the mechanism of transport of plant seeds to new sites for germination and the establishment of new individuals and colonies.
- This depends upon the effectiveness of the seed dispersers.
- Seed dispersal occurs by wind, water, animals, bats, explosions or gravity of the earth.
- Dispersal of seeds is very important for the survival of plant species.
- If the plants of same type grow too closely, they have to compete with each other for light, water and nutrients from the soil.
- Seed dispersal allows plants to spread out from a wide area and avoid competing with one another for the same resources.

1. No conversions. The greatest advantage of SI is that it has only one<span> unit for each quantity ( a type of measurement). This means that it is never necessary to convert from one unit to another (within the system) and there are no conversion factors for students to memorize.
2. </span><span>No fractions. SI uses decimals exclusively, eliminating clumsy fractions and mixed numbers.</span>
