Answer:
Temperature is usually uniform throughout a cell (Ans. C)
Explanation:
Heat or thermal energy is a kinetic energy. That is connected with the random movements present in the atoms. Temperature is usually uniform throughout the cell so the most cell can not harness heat to perform work.
Heat is a type of energy which is transfer from one body to another body due to the temperature difference.
It can only perform work if it is transferred from one source which is warmer to a body which is cooler. The temperature in living organisms is usually kept very constant due to the process of homeostasis.
Answer: 1.building storm cellars and wind-resistant structures.
3.using more radars and satellites in the area.
A tornado is a storm of wind. In tornado the high speed wind takes the form of a cone that destroys anything that comes in it's path. The following techniques can help in reducing the effects of tornadoes:
1. building storm cellars and wind-resistant structures: This will provide support and protection to the building against high speed wind currents during an event of tornado.
3.using more radars and satellites in the area: This will help in identification of origin of wind producing tornado in a region so as to create awareness about the coming calamity. This will allow people to relocate to safer place and can take preventive measures.
