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>
Answer:
Cancer is basically a disease of uncontrolled cell division. Its development and progression are usually linked to a series of changes in the activity of cell cycle regulators. For example, inhibitors of the cell cycle keep cells from dividing when conditions aren’t right, so too little activity of these inhibitors can promote cancer. Similarly, positive regulators of cell division can lead to cancer if they are too active. In most cases, these changes in activity are due to mutations in the genes that encode cell cycle regulator proteins.
