Answer:
Conceptual.
Explanation:
Conceptual method includes a diagrammatic representation of biological life cycle. It helps in better understanding of the life cycle of an organism. Betty is also using conceptual method to illustrate the life cycle of butterfly. The diagrams show various stages of growth of butterfly in a picture form. This enables the students to easily understand the phenomena.
I would have to say no. There are metamorphic rocks, igneous rocks, and sedimentary rocks. Igneous rocks are rocks that have solidified from magma or lava upon cooling, like lava rocks. Sedimentary rocks are rocks from smaller sediments, such as sandstone being made from, well, sand. Metamorphic rocks are the result of preexisting rocks in a response to changes in the environment. This includes changes in pressure, air temperature, mechanical stress, as well as taking away or adding chemical components. Metamorphic can be from igneous, sedimentary, or any other metamorphic rocks. Hopefully this help (with the added bonus that I explained all three type of rocks.
