Answer:
In the electromagnetic spectrum, the visible spectrum is the part, which is perceptible to the human eye. The electromagnetic spectrum in this array of wavelengths is known as simply light or the visible light. A general human eye will react towards the wavelengths in the range between 380 to 740 nm. A human eye sees the sky as blue that comes in the wavelength 490 nm because of the scattering of the visible light by the particles in the atmosphere. This concludes that 490 nm is the sole wavelength, which is reaching the eye.
Epiglottis
The epiglottis is a flap of cartilage the covers the entrance to the throat protecting the lungs from obstruction. It moves when we swallow to allow food in.
I also believe the answer is A.
G. cause if you just do a ratio everything adds up.
Alcohol fermentation produces carbon dioxide gas as a by-product, and this is why alcohol fermentation is more suitable for baking. Alcohol fermentation occurs when breads are made. The carbon dioxide gas is what creates tiny air bubbles within the dough and makes bread be the light consistency we are used to. In contrast, bread made without yeast (alcohol fermentation) is very flat.
