In humans, we have nutrients or food, oxygen and water for us to survive. These are stimuli, eyes need light as a stimuli for it see and function. Nasal receptors needs smell as stimuli caused by molecular reactions of an object as a stimuli. And others.
Explanation: Wave velocity (m/s) =Wavelength (m) * Frequency (Hz) Example calculation. I found this by using calculation of wavelength times frequency and the answer will be your velocity.
Food is made up of cells. those cells contain theyre own DNA without it they wouldnt exist. and when we consume it from other organisms it dies and breaks down and doesnt enter the blood stream
