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.
Explanation:
Using things such as the internet. For example, if a scientist wanted feedback, he could turn to an org of other scientists across the globe and get their help.
my but need filtering lol
Answer:
The correct answer would be option D, Can help make sense of difficult problems.
Explanation:
In simple words, simulation is the Model. Simulation is the imitation of some procedure or method or process or situation. We can say it deception as well. Simulation is used as a method of analysis. When there are complex situations or processes that need to be tested before launching into the general public or to be used in the scientific researches or anything, Simulation is used. Simulation imitates the situation, checks for any errors, experiments the inputs and see the outputs of the process, method, system, etc, which they have developed. So A scientist uses simulation because it can help make sense of difficult problems.
