Answer:
It's B: As the frequency of a wave increases, the shorter its wavelength is.
Explanation:
Thanks
Running up a tree after running straight is a change in direction thus, although the speed is same 30mph, the velocity is different. Now, in choice B, the cat is slowing down after having escaped from the dog. This is also a change in velocity (because the speed decreases).When the cat is sitting still the whole time, its velocity is 0.0mph the entire time. That means the velocity doesn't change <span>And when the cat is running around the house, the cat is changing direction (thus velocity is different).
(This is relevantly a circular motion, and acceleration is a non-zero constant, and thus veloicty of course isn't same).</span>
Exoskeleton
Exoskeleton is a evolutionary innovation. This is operated by muscles attached to it and acts as an armor. Other than support this is an adaptive mechanism to provide protection against predators. In vertebrates, it is considered as the dermal bone that developed via membranous ossification. Fishes retained their exoskeleton in the form of their scales. However, in some organisms terrestrial evolution allows the loss of exoskeleton and formed a more mobile endoskeleton,
The answer should be B if I help you out pls mark me as a brain less
