The speed of a longitudinal wave will not be affected by the temperature of its surrounding. Base on the formula for the wave speed (applicable on longitudinal wave), wave speed ( speed in m.s 2) is equal to the distance of a wave (wavelenth in meter) travel over a unit of time (seconds) or wave speed is equal to distance of a wave times the frequency (hertz), temperature is not included in calculating the wave speed.
Answer:
Why Redi and Pasteur refute the theory of spontaneous generation.
The answer is '<span>Exaptation</span>'. This term describes the change in the function of a trait developed during evolution, i.e., a trait that evolved to fulfil one function, eventually serves to fulfil another function for which it was not originally evolved. It is thought that this is common in animal anatomy and behaviour. For example, bird feathers may have initially evolved for temperature regulation, but later were adapted for flight.
Answer: The DNA of the organism in that area.
Explanation:
Phosphate is found in the DNA of the organism. If the food is contaminated with the radioactive phosphate then it can be examined by the DNA of the organism that had food contaminated with phosphate.
The DNA of the organism consists of the nitrogenous bases, ribose sugar and phosphate.
The traced amount of phosphate can be found in it only.
