Russ makes the diagram below to organize his notes about how newton’s first law describes objects at equilibrium. A venn diagram shows 2 intersecting circles, with the left circle labeled dynamic equilibrium and the right circle labeled static equilibrium. There is an x in the intersecting section. Which label belongs in the region marked x? has a net force of zero has a velocity of zero is moving with a constant velocity is slowing down and coming to rest.

Snakes, dogs, and humans have a vertebral column. snakes and dogs have tails, and humans have vestigial tailbones. dogs and humans have limbs, but snakes do not. most reptiles lay eggs, but a few give birth to live young. what do these structures suggest about the evolutionary pattern between the three organisms? 1. snakes and dogs are more closely related than snakes and humans. 2. snakes and humans are more closely related than humans and dogs. 3. dogs and humans are more closely related than snakes and humans. 4. dogs, snakes, and humans share a common ancestor. 5. the early ancestor of snakes and dogs is the same, and the early ancestor of humans is different.
