If a sound wave speeds up and its frequency does not change, what happens
to the wavelength?

Wave speed, frequency and wavelength in refraction

Explanation:

Although the wave slows down, its frequency remains the same, due to the fact that its wavelength is shorter. When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases.

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.

colors do exist. the color of the sky is actually violet; humans percieve the color of the sky as blue.
