According to this phyletic lineage, Cambrian (542 to 488 million years ago) and Silurian (443 to 416) are younger than Triassic (251 to 199), whereas Jurassic (199.6 to 145.5), Cretaceous (145 to 65), and Neogene ( 23 to 2.6) came later.
Answer: Wind energy can harm migrating birds.
Explanation: Cost doesn't make it controversial, and the first two make me laugh!
I think structure however I am not sure so keep that in mind.
54. Amphibians are cold-blooded animals, meaning they do not have a constant body temperature but instead take on the temperature of their environment. They have moist, scaleless skin that absorbs water and oxygen, but that also makes them vulnerable to dehydration (loss of bodily fluids).
55. The first and foremost characteristic of the reptiles is that are cold blooded. They are able to regulate their inner body temperature to the temperature of the environment. They have scaly skins but absence of hair or fur. The scales of the reptiles develop as a surface cells filled with Keratin.
56. Characteristics of Birds. Birds are endothermic and, because they fly, they require large amounts of energy, necessitating a high metabolic rate. As with mammals, which are also endothermic, birds have an insulating covering that keeps heat in the body: feathers.
