Question

We can get the smell of perfume several metres away​

Answer 1

Explanation:

When perfume is released it quickly changes into vapour. The kinetic energy of gas molecules is high & the rate of diffusion is high. Hence we can smell the perfume sitting several metres away.

Answer 2

Answer:

Urination of adults, as well as infants, is controlled by the neural circuit which is very complex and highly distributed as it involves pathways at many levels of the brain, spinal cord and the peripheral nervous system and is mediated by multiple neurotransmitters.
