  • c)
    conidia and conidiophores
  • d)
    all of the above
Correct answer is option 'C'. Can you explain this answer?

 Conidiophore - Erect fungal filament on which conidia are formed is called conidiophore.

 Conidia - Conidia are formed in chain. Each conidium forms new fungal filament (mycelium) by germination.

       
  Hence, conidia and conidiophores are genetically identical  (option c).

The common name of any species is much simpler than its scientific name. However, the scientific name is more acceptable to biologists all over the world in scientific studies than common names. This is because different countries have different languages and different name for the single species. This would create confusion. Hence, use of scientific names has an advantage over the common name

    Planck's law of radiation
  • b)
    Rayleigh jeans law

    Wien's law
  • d)
    Stefan's law of radiation
Correct answer is option 'C'. Can you explain this answer?

Raza Great answered  •  5 hours ago
Wien's law states that when the temperature of a black body radiator increases, the overall radiated energy increases and the peak of the radiation curve moves to shorter wavelengths. λT=b where T is the temperature and λ corresponds to the wavelength around which maximum energy radiated

What happens to the dispersive power of prism when the prism is immersed in water.?

Testigo Sãkshï Erudito answered  •  16 hours ago
Μ = refractive index of glass of prism wrt to air or water as the case may be. Refractive index of glass wrt water is less than wrt to air. Hence angle of deviation is less. Hence dispersive power is less.
Glass prism works on the principle that lights with different colours travels with different speed in solid and liquid medium. So when a glass prism is dipped in water the light that reach
