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.

Answer:
Biosphere is the one of the sphere of geological sphere of the earth such as geosphere, hydrosphere and atmosphere. It is deal with the interaction and existence of the living organisms.
In this model it can be seen that there are human, fishes, and vegetation of plants are living organisms so living organisms in the hydrosphere (fishes), geosphere (plants) and anthrosphere (human) should be label as biosphere instead of atmosphere or with atmosphere.
 
        
             
        
        
        
Answer:
<em>They differ from both parents and also from each other. This occurs through a number of mechanisms, including crossing-over, the independent assortment of chromosomes during anaphase I, and random fertilization. When homologous chromosomes form pairs during prophase I of meiosis I, crossing-over can occur.</em>

It gives a better foundation for the top part of your vertebrae (that are smaller), as it is bigger, it can support the rest of your vertebrae better.
