Advantages and disadvantages of nuclear power stations
Generating electricity using nuclear reactors carries high risk but offers large rewards. In operation, a very small amount of nuclear fuel will consistently generate a very large amount of electricity and generate very little polluting material. However, the financial costs of building and decommissioning a nuclear power station are very large, and the waste produced will remain radioactive - hazardous to humans and the environment - for thousands of years.
Produces no polluting gases. Waste is radioactive and safe disposal is very difficult and expensive.
Does not contribute to global warming.Local thermal pollution from wastewater affects marine life.
Very low fuel costs. Large-scale accidents can be catastrophic.
Low fuel quantity reduces mining and transportation effects on environment. Public perception of nuclear power is negative.
High technology research required benefits other industries.Costs of building and safely decommissioning are very high.
Power station has very long lifetime.Cannot react quickly to changes in electricity demand.
One example could be a Catfish, hope i could help out.
Answer:
The apical meristem, also known as the “growing tip,” is an undifferentiated meristematic tissue found in the buds and growing tips of roots in plants. Its main function is to trigger the growth of new cells in young seedlings at the tips of roots and shoots and forming buds

Please rate me 5 star and thank me
Sorry the answer took so long hope this help :)
Answer:
Less biological relevant model and reduce cell to cell interaction.
Explanation:
The two main disadvantages of a 2D model of the digestive system is that it is less biological relevant model and reduce cell to cell interaction. The 2D model does not show high resemblance to reality and this model also fail to show the interactions of two cell surfaces with each other. In short, this model, does not give us complete knowledge about any biological system.
