Answer:
With the appropriate security measures nuclear power, as well as other energy sources, can be used safely.
Explanation:
Nuclear energy, as well as other energy sources, can be dangerous if we do not take the appropriate prevention and protection measures. <u>Nuclear power has one of the lowest levels of fatalities per unit of energy generated, as well as low levels of air pollution-related deaths and allows the reduction of carbon dioxide emissions compared to other energy sources.</u> <em>Since its commercialization, in the 70s, the number of nuclear power accidents is very low compared to the number of accidents of other energy sources, having that </em><em>coal mining is the most dangerous energy activity in history.</em><em> </em>
I think that without the correct security considerations, all the energy sources can be dangerous, but if we take security measures as using protection barriers, controlling the reactivity of nuclear power plant, making regularly quality and prevention test control, as well as other measures, we can have the benefits of the nuclear power without worrying too much for danger.
Therefore, with the appropriate security measures nuclear power, as well as other energy activities, can be used safely.

Answer:
Examples of storage polysaccharides - <u>starch and glycogen</u> and structural polysaccharides - <u>cellulose and chitin</u>
Explanation:
Polysaccharides are the complex carbohydrate polymers, composed of monosaccharide units that are joined together by glycosidic bond.
In other words, polysaccharides are the carbohydrate molecules that give monosaccharides or oligosaccharides on hydrolysis.
The examples of storage polysaccharides are starch and glycogen. The examples of structural polysaccharides are cellulose and chitin.
