3. Nuclear power station or plants obtain heat required to heat water to produce steam from nuclear fission reactions (physical process) which entails the splitting of atoms of uranium in the nuclear reactor. The uranium fuel consists of small, hard ceramic pellets that are packaged in to long vertical tubes and are inserted into the reactor. The steam produced then turns turbines to produce electricity. Therefore the correct answer is C.
10. Nuclear fission reactions are physical processes that involves splitting of radioactive isotopes to form other stable atoms coupled with production of energy. Chemical reactions on the other hand are reactions involving rearrangements of atom structure to form other substances (products). Nuclear fission reactions are not affected by the environmental factors such as temperature while chemical reactions are affected by these changes, therefore increase in temperature affects chemical reactions but doesn't affect nuclear reactions. Therefore, the correct answer is A
Answer: In places of hot climate it is advised that the outer wall of houses be painted white because white color reflects heat and the houses do not heat up too much.
Larva, pupa, and egg are insects life cycle
Spore, seed, fruit, and cone are animal life cycle
