Light speed in water is 2.25 times 10^5 m/s so the index of refraction is higher than the index of refraction of light in a vacuum which is 1.0. (speed in vacuum for light is 300,000 km/s)
Index of refraction of light in water is 3.0 time 10^5 m/s divided by 2.25 times 10^5 m/s = 1.33.
Hope this is what you wanted.
Bird flu is a relatively new disease. Hope this helps!
<span>It binds itself to the receptors present on the surface of the cell membrane, which activates the enzymes present inside cell. Then It passes through the cell membrane and attaches itself to a receptor protein present in the cytoplasm.
It passes on the signal to the secondary messengers inside the cell, which activate the receptors on the cell membrane.</span>
Predator prey relationship, is just basically when the predator eats the prey. Like for example if cheetah eats the zebras, through time zebras can become less of a population. But then think of this, if there was NO prey zebras could over populate and there may not be enough places for them to live or enough food. Hope that helped...
