The genetic code is the set of rules by which information encoded in genetic material (DNA or RNA sequences) is translated into proteins (amino acid sequences) by living cells. Those genes that code for proteins are composed of tri-nucleotide units called codons, each coding for a single amino acid.
Photosynthesis and cellular respiration are opposites
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.

The correct answer is: 2.metaphase.
Mitosis is a process of cell division and it is separatd into phases.
• Interphase-DNA replication (two identical full sets of chromosomes),
• Prophase-chromosomes composed of two sister chromatids with identical genetic information,
• Metaphase- chromosomes line up along the centre of the cell,
• Anaphase- chromatids are pulled apart by the mitotic spindle (one chromatid to one pole and the other chromatid to the opposite pole),
• Telophase- a full set of chromosomes at each pole of the cell.
