As your body gets older, it is less able to produce vital nutrients naturally, so it is recommended that adults take multi vitamins, to help offset the loss in vitamins and minerals.
Mainly because our lungs are made to intake air, and if we where to inhale water we would drown. oxygen can only be obtained from the air because our lungs would be able to expell the excess stuff from air easier than in water. hope i helped.
Water
The electrons stripped from glucose first end up forming oxygen as cellular respiration proceeds with the electron transport chain (step). Eventually, the oxygen is combined with the hydrogen ions initially released or split from glucose by the dehydrogenase enzyme. The reaction between oxygen and hydrogen ends up forming water.
<u>Answer:</u>
You try to pick up a shell in the water but it isn't where it appears to be is an example of diffraction
<u>Explanation:</u>
Diffraction refers to the light bending that happens as the light passes about the edge of some object. How much bending takes place is found by the size of wavelength of light relative to that of opening. If the opening is larger than the wavelength of light, then bending will not be noticeable.
Since, light gets diffracted due to water hence the shell kept inside the water appears to be at a different position than where it actually is
