Answer the following question given this paragraph: Amphibians were the first animals to have true lungs and limbs for life on land. However, they still had to return to water to reproduce. That's because their eggs lacked a waterproof covering and would dry out on land. The first fully terrestrial vertebrates were amniotes. Amniotes are animals that produce eggs with internal membranes. The membranes let gases but not water pass through. Therefore, in an amniotic egg, an embryo can breathe without drying out. Amniotic eggs were the first eggs that could be laid on land. Q: What were the first animals to have true lungs and limbs for life on land? A:

OPTIONS:
- birds
- mammals
- reptiles
- amphibians

Answer: amphibians

Answer the following question given this paragraph: Figure 10.18 The first image shows how helicopters store large amounts of rotational kinetic energy in their blades. This energy must be put into the blades before takeoff and maintained until the end of the flight. The engines do not have enough power to simultaneously provide lift and put significant rotational energy into the blades. The second image shows a helicopter from the Auckland Westpac Rescue Helicopter Service. Over 50,000 lives have been saved since its operations beginning in 1973. Here, a water rescue operation is shown. (credit: 111 Emergency, Flickr). Q: Helicopters store large amounts of rotational energy of what type in their blades? A:
OPTIONS:
- magnetic
- seismic
- thermal
- kinetic
kinetic
