"The incredible diversity of pterosaurs is perhaps best expressed in one of the prehistoric flying reptile's most intriguing and mysterious features: the head crest."
What evidence from the text supports the idea that the diversity of pterosaurs is best
expressed in their head crests?
A "Many pterosaurs had flesh-and-bone crests atop their skulls - dramatic
anatomical characteristics whose purpose is still debated by paleontologists."
B "Akin to a rooster's comb, peacock's crown, or the frill on some lizards!
necks, pterosaur crests were prominent anatomical features found across many
species."
C "Pterosaurs crests are thought to have been fairly ubiquitous, appearing in
many groups of pterosaurs from the Triassic (252-201 million years ago)
through the Jurassic (201–145 million years ago) and Cretaceous (145-66
million years ago) periods."
D "Among pterosaur species known to have had crests, there is an amazing
range of shapes and sizes."

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.

Which explanation is true about what happens to a ray of light when it strikes a mirror? a. a light ray is transmitted toward a mirror at a certain angle. the light ray is then reflected by the mirror at an equal angle but in the opposite direction of the transmitted ray. b. an incident ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then reflected at an angle equal to the angle of incidence but on the opposite side of the perpendicular line. c. a reflecting ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then refracted at an angle equal to the angle of the reflecting ray and on the same side of the perpendicular line. d. an incident ray strikes a mirror at an angle with a line parallel to the mirror. the light ray is then transmitted at an angle equal to the angle of incidence but on the opposite side of the parallel line. you so much! : -d take the time to try and answer correctly.
