Hello!
In order for an animal to be a vertebrate, it must have a backbone. As can clearly be seen in any image of a sponge, it is a highly asymmetrical simple animal and does not have a backbone. Therefore, a breadcrumb sponge is not a vertebrate, or is an invertebrate.
I hope this helped!
Frost action or frost shattering?
The answer would be (B) Mediterranean. The Mediterranean climate stays between 60 and 30 degrees year round, and rarely dips below freezing. We can rule out tundra because it says below freezing year round. We can also rule out the highlands because the further up in elevation you go, the colder it gets. And finally, we can rule out the humid continental because its seasons are polar opposites. The humid continental has hot summers and freezing cold winters.

Answer:
Seismic tomography
Explanation:
Seismic tomography is a technique for imaging the subsurface of the Earth with seismic waves produced by earthquakes or explosions. P-, S-, and surface waves can be used for tomographic models of different resolutions based on seismic wavelength, wave source distance, and the seismograph array coverage. The data collected can be represented in a 3D image for further investigation.
