In contrast to their grazing, scavenging, and filter-feeding cousins, squid are molluscs that have evolved for a life of active hunting in
the open ocean. Describe TWO external and TWO internal
adaptations that cephalopods have (but gastropods and bivalves
lack) that are specifically for this predatory, open water lifestyle.

Which statement correctly describes a way that mutations increase the likelihood that a species will survive in a changing environment

Subduction zones form when an oceanic plate collides with another oceanic plate or continental plate. the continental crust is lighter and less dense than oceanic crust. continental crust's density is approximately 2.7 grams per cubic centimeter. oceanic crust is thinner and the average density is about 3.3 cubic centimeters. when the two crustal plates converge the oceanic plate always bends and subducts beneath a continental plate. once the oceanic crust subjects, the rocks are subjected to changes in heat and pressure. because of this, we would expect to find rocks in the area of a subduction. a) clastic b) igneous c) metamorphic d) sedimentary

Creating new things to solve problems and improve life depends on the close interaction of which two fields?
