Question

Define following terms.
i) Solar photovoltaic effect ii) Health iii) Twins ​

Answer 1

1. The photovoltaic effect is the generation of voltage and electric current in a material upon exposure to light. It is a physical and chemical phenomenon. The photovoltaic effect is closely related to the photoelectric effect.
2. Health, according to the World Health Organization, is "a state of complete physical, mental and social well-being and not merely the absence of disease and infirmity". A variety of definitions have been used for different purposes over time
3. Twins are two offspring produced by the same pregnancy. Twins can be either monozygotic, meaning that they develop from one zygote, which splits and forms two embryos, or dizygotic, meaning that each twin develops from a separate egg and each egg is fertilized by its own sperm cell.
