The frequency increases.
Here's an easy way to think about this. The wavelength is the distance from crest to crest, or trough to trough -- equivalently, it's the distance the wave travels in one period. This means that the speed of the wave is the wavelength divided by the period, or <span><span>v=<span>λT</span></span><span>v=<span>λT</span></span></span> . But the frequency is just the reciprocal of the period, so <span><span>v=λf</span><span>v=λf</span></span>. Clearly, if v increases and the frequency stays the same, the wavelength must increase by an equivalent factor.
<span>Mutations sometimes improve the chances of survival for an animal.
But rather rarely. Advantageous mutations do happen, but neutral and harmful mutations are way more common.

answer is : b. the universe ♡
Weaker gel concentration could make the lines on the graphs closer together
They have kingdom, class, and phylum, I’m kind of confused about the answer because of that.
