The distinction between sponges and other animal phyla is based mainly on the absence versus the presence of

We know that 0 K = - 273 deg C , or more accurate: - 273.15 deg C ( an absolute zero ): If we want to transform Celsius degrees to Kelvin, we have just to add 273 to the temperature that we have in degrees Celsius( C + 273 = K ). In this case we know that person`s temperature is 40 degrees C. 40 + 273 = 313 K. D ) 313 K.
