Kelly created a short animated film on the life cycle of a butterfly. each stage showed various activities of the insect, such as eating, molting, and an embryo growing inside an egg. one stage caused a dramatic change in the organism’s body structure. which stage would this be?

The pupa or chrysalis stage

Explanation:

The pupa or chrysalis is the last step that will lead to transforming a caterpillar into a butterfly, which is the previous step to the adult stage. At that time the caterpillar stops eating, and begins to look for a safe place to pupate, usually near the place where it has lived, among the branches of the plant that has served as a guest, or in its surroundings.

Caterpillars use different formulas to create chrysalis buds, depending on the family to which they belong.

the earth’s crust is broken into separate pieces called tectonic plates (fig. 7.14). recall that the crust is the solid, rocky, outer shell of the planet. it is composed of two distinctly different types of material: the less-dense continental crust and the more-dense oceanic crust. both types of crust rest atop solid, upper mantle material. the upper mantle, in turn, floats on a denser layer of lower mantle that is much like thick molten tar.

each tectonic plate is free-floating and can move independently. earthquakes and volcanoes are the direct result of the movement of tectonic plates at fault lines. the term fault is used to describe the boundary between tectonic plates. most of the earthquakes and volcanoes around the pacific ocean basin—a pattern known as the “ring of fire”—are due to the movement of tectonic plates in this region. other observable results of short-term plate movement include the gradual widening of the great rift lakes in eastern africa and the rising of the himalayan mountain range. the motion of plates can be described in four general patterns:

collision: when two continental plates are shoved together

subduction: when one plate plunges beneath another (fig. 7.15)

spreading: when two plates are pushed apart (fig. 7.15)

transform faulting: when two plates slide past each other (fig. 7.15)

sumerians were polytheistic, meaning they believed in many different gods. so, the best answer is c.
