Answer:
The transfer of mature pollen grain from anther of the flower to the stigma of the same flower of the same [species is called self pollination.
Generally, the transfer of pollen grains by wind,animals,and water to stigmas is called pollination. It is a means of vegetative propagation which ensures reproduction.
Therefore during self pollination, the same genes are distributed from one generation to another. Thus genetic purity is ensured. It also ensured reproductive success. because there is little chance of the pollen grain getting lost in transit. It is also certain a particular plant would always breed true.
Additionally it prevent the process of transfer of genes in some transgenic crops( rice, maize) where through genetic engineering some genes are introduced in their genome.
The only negative effect is lack of genetic diversity. Therefore after a period of time the plants get weak and prone to diseases and infection. Because of poor resistant from lack of variation.

Answer:
Basic science of hatching of egg into chick is incubation.
Explanation:
Incubation is the process of keeping eggs at suitable temperature and under suitable conditions, so that it can develop.
The answer is <span>0.5 m/s².</span>
The formula that will be used is
F = m · a
where
F - the force of the object,
m - the mass of the object,
a - the acceleration of the object.
It is given:
m = 1,200 kg
F = 600 N
a = ?
F = m · a
⇒ a = F ÷ m = 600 N ÷ 1,200 kg = 0.5 m/s²
