Answer;
-Frequency
Explanation
-Wave frequency is the number of waves that pass a fixed point in a given amount of time. The SI unit for wave frequency is the hertz (Hz), where 1 hertz equals 1 wave passing a fixed point in 1 second. A higher-frequency wave has more energy than a lower-frequency wave with the same amplitude.
-The speed of a wave is dependent on four factors: wavelength, frequency, medium, and temperature. Wave speed is calculated by multiplying the wavelength times the frequency. Since speed is constant within the same medium, a high frequency has a short wavelength and vice-a-versa

Answer:
Option d: black 75%, white 25%
Explanation:
The cross is between a homozygous black and a heterozygous black guinea pig
Parents gen. BB x Bb
F1 generation BB Bb Bb bb
The probability of an offspring with the same phenotype as its parents is
Genotype: BB - 25% and Bb - 50%, bb-25%
Phenotype: black 75%, white 25%
