Answer:
Explanation:
Electromagnetic waves all travel at the speed of light when in vacuum, and essentially this same speed in normal air. Since wave speed is product of frequency and wavelength, c = f λ and λ = c/f = (3.00 x 108 m/s) / (7.5 x 1014 Hz) = 4.00 x 10-7 m = 400 x 10-9 m = 400 nm.
I’d say, Humans have the ability for rational thought
Hope it works. Good luck :)
It would be B. XY, XY, XY, XY, XX, XX, XX because the male gamete is Y, meaning 4 of these kittens are male, and 3 are female because they lack a Y gamete.
